Tomato vaccine against COVID-19
27.08.2021

At a time when the whole world is fighting the Corona Virus pandemic, scientists from Uzbekistan have begun to grow a tomato vaccine against COVID-19.

The first edible vaccines produced in Uzbekistan will mature in two months, uznews.uz writes.

According to the Sevimli TV channel Zamon, a person who eats such a tomato is vaccinated against a coronavirus infection.

“We introduced the coronavirus into the plant cell by cloning. After the patient eats the "vaccinated tomato", it enters the human body, and antibodies are released from the tomato cells, "says one of the scientists of the Center for Genomics and Bioinformatics of the Academy of Sciences of the Republic of Uzbekistan.

It is known that the scientists of the Center have been developing this edible vaccine since January of this year.

How do you like this news? Would you prefer to eat a tomato or get vaccinated?

Growing in the soil - reducing greenhouse investment
20.08.2021

If you want to reduce the investment of your greenhouse, then growing in the ground may be the best solution for you. So you can grow all crops, protecting them from frost, wind, hail and / or excessive sun exposure.

Some plants are specially grown in the soil, such as chrysanthemums and bulbs (tulip, onion, etc.). They can be planted directly into the ground, or in boxes and / or on racks for easy care and harvesting.

Often, in garden centers, greenhouses are used to keep plants in the winter, so just leave them on the ground, without any cover or additional growing systems.

Therefore, to reduce costs at the start of greenhouse production, you can start with growing in the ground, and later the greenhouse can be equipped with the necessary hydroponic systems.

All your life you have dreamed of a greenhouse business and you don't know where to start? Call, we will help you!

The main pests in greenhouses
13.08.2021

The main task when growing indoors is to create the most comfortable conditions for plants, close to natural ones. Heat, light, humidity, air circulation ... At the same time, with such conditions, we also create an ideal breeding ground for the development of pests. The most common greenhouse pests are: aphids, fungal midges, thrips, whiteflies, root aphids and mites.

Aphids are a typical greenhouse pest that feeds on a variety of plants, piercing leaf cells and sucking out nutrients. Carrier of plant viruses, secretes honeydew waste products that can be found on leaves. When the plant is heavily infested, in addition to translucent wet spots, the leaves may turn yellow. stains become an ideal breeding ground for mold or fungal diseases.

Thrips are serious greenhouse pests that feed on a wide variety of plants, piercing the surface cells of leaves and sucking out cell contents with their stylets. As a rule, they feed on buds and new leaves. Bronze or silvery leaf scars and tiny black spots of fecal excrement are visible on heavily damaged leaves.

Whiteflies are white, soft-bodied winged insects of a triangular shape, often found in clusters on the underside of leaves. Whiteflies suck sap from plant stems and leaves. Due to large populations, the leaves may turn yellow, dry, or fall off. Like aphids, whiteflies secrete a sweet liquid called honeydew, so the leaves can be sticky or covered in black mold.

Root aphid - Extracts sugar-rich juice from roots, bulbs and rhizomes. Minor root aphid infestations do not cause significant damage to plants, but as populations increase, root wounds can become entry points for root disease pathogens. Plant roots cannot absorb nutrients and therefore may lack nutrients in the leaves. Plants often lose growth, are smaller and may wilt, especially in hot weather. Root aphids do not move quickly, so infections are often limited to a few plants and spread slowly at first.

Fungal flies are small flies that develop in the growing environment. Adults are 3 mm long, with long legs and antennae. The larvae mainly feed on fungi, algae and decaying plants, as well as plant roots. Wet culture media containing large amounts of peat moss are especially attractive to adult females. Plants infested with numerous mushroom mosquito larvae may experience stunted growth.

Spider mite - It feeds on various types of plants, sucking the contents of plant cells through a pair of sharp stylets. Spider mites are tiny (about 0.5 mm long) arachnids with 8 legs and a creamy appearance. Spider mite populations can grow exponentially in a very short period of time. Eggs are laid in clusters on the underside of the leaves. The initial stage of colonization usually begins in the lower third of the plant. The lesion initially appears as pinpoint or yellowish-reddish-brown spots on the leaves, which are arranged in accordance with the groups of colonies usually found on the underside of the leaf. The leaves turn yellow at first, and at high drying density they dry out and die off.

All of these pests cause incredible damage to your plants, and ultimately to your crops and economy. In order not to start the situation, it is necessary to monitor and diagnose the presence of insects.

Some tips on how to grow in a greenhouse in summer
06.08.2021

During some of the hottest and driest summer months, your plants need extra care. Namely: watering, feeding, pest control and shading are key components of successful glass growing.

Watering. Do not allow the soil to dry out; watering should be carried out before the plants begin to feel a lack of moisture. Best of all is evening watering. Extremely hot and sunny weather may require re-watering in the morning and at noon, but be careful not to splash on leaves or fruits. This can damage and burn the leaves. Do not water the plants with too cold water! A sharp temperature drop for plants is always stress.

Top dressing. Do not neglect plant nutrition, especially such as tomatoes, cucumbers, peppers and eggplants. Establish a regular feeding schedule, for example, always apply it along with the appropriate fertilizer on the same evening every week.

Remember that you are creating this extremely important warm and humid atmosphere that many pest species also love. If “unwanted guests” have already appeared in your greenhouse, treat the pests with appropriate biological pesticides. Always read the instructions carefully before processing plants and store the concentrated product in a cool place, out of direct sunlight and out of reach of children.

Shading is one of the important systems in the greenhouse at any time of the year, especially in summer. This is the main protection against direct sunlight. Have you noticed that it will always be a little cooler in a shaded greenhouse than in an unprotected one?

Airing. Keep doors and windows open to allow good circulation of fresh air. The automatic window opening system will help to minimize your participation in the control of this process.

We will help you create the most comfortable conditions for plants in the greenhouse! And you, in turn, will get an excellent and tasty harvest!

Are vegetables from the greenhouse as tasty as from the garden?
29.07.2021

Have you ever seen barely pink tomatoes on the shelves in the store? You buy them, go home and cut them for salad. Taste and understand that there is almost no taste! Have you been in similar situations?

In fact, this is usually the case: there are farmers in Turkey or Morocco who grow tomatoes specifically for export. They select the appropriate variety of tomato for export, which is well transported. Such varieties are usually less sweet at first and harder than usual.

In order for a tomato to be on the road for a long time (a week or even two), and even to lie on the shelf for a few days, it is plucked completely green. The color, reaching, he "gains" on the road. And now this tomato, not fully ripe in the greenhouse and not gaining enough sugar, came to the shelf from which you took it.

Compare this tomato with the one grown on a farm near you. Of course, this tomato will cost more, because the greenhouse needs to be heated and lit. But the taste is rich, the tomato is useful, fragrant and delicious.

So let's grow delicious tomatoes in Ukraine all year round! After all, there is always a demand for tasty products.

How? - we will help in this.

The effect of clear and diffuse glass covering on cucumber fruit yield
09.07.2021

Using proper greenhouse covering materials can provide a more suitable environment for plant growth in Saudi Arabia. The effects of three different greenhouse covering materials, clear glass, polycarbonate and diffuse tempered glass were used to evaluate its effect on cucumber productivity, water, and energy use efficiency.

Results show that either water or light use efficiency was higher in compartments covered with diffused or clear glass than polycarbonate compartments. In consequence, the fruit yield of cucumber plants/m2 was significantly higher (58%) in clear and diffuse glass greenhouses as opposed to polycarbonate greenhouses. In terms of the effect of cultivar or plant density, no significant differences in cucumber yield were found. The use of different covering materials did affect the environmental data of greenhouses. Less light was transmitted through polycarbonate cover than clear or diffuse glass.

The photosynthesis active radiation (PAR) was 996, 1703, 1690 mol/m2/d, while the electricity consumption was 2.97, 3.44, and 2.88 kWh under polycarbonate, clear glass, and diffuse glass, respectively. Meanwhile, diffuse glass compartment revealed 16% lower of water consumption than other covering materials. In this respect, it could be concluded that using diffuse glass, as a greenhouse cover material, has a strong positive influence on crop productivity under Saudi Arabia climate,  write https://www.hortidaily.com

PERSPEKTA uses all these coating materials to build greenhouses of your choice.

We will be happy to put all your ideas into practice!

What to do if there is too much light in the greenhouse?
02.07.2021

There is a lot of direct sunlight in the summer months. If plants are not protected, photosynthesis and other plant growth processes stop. When the temperature of the environment and plant tissues becomes very high, all the water consumed by the plant is used to cool the plant tissue. In this case, the plants do not work to bear fruit, but to survive. As a result, you will not receive a harvest, which means a profit.

To create a comfortable climate that will save your income, a number of systems are used, the main of which is the curtain system. For different types of crops at different stages of the growing season it is necessary to reduce the intensity of sunlight and the heat to which the crops are exposed. This is especially important in nurseries and when planting seedlings.

With the help of curtains you can adjust the lighting, temperature, humidity and save a lot of heat. Special greenhouse fabrics are used, which perform the following functions: reduction of overheating and reduction of heat consumption, light scattering.

The curtain system evenly scatters sunlight on the surface and inside the plants, accelerating their growth and promoting the development of healthy and homogeneous products.

And also creates a favorable shade and allows light to penetrate deep under the entire surface of the plant. As a result, the process of photosynthesis is improved and the yield in the whole greenhouse is increased.

Fogging system for humidifying and cooling greenhouses
25.06.2021

Controlling the microclimate in greenhouses is an important part of efficient production and consistent yields. Together with lighting, temperature, nutrients and CO2, humidity plays a decisive role in creating an ideal and stress-free climate. Especially in hot weather, cooling is very important to maintain the required microclimate and the proper development of plants.

In combination with curtains to reduce the air temperature in summer, we recommend an evaporative cooling and humidification system, also called "fogging" and "fogging systems". In our opinion, this is the most effective system for our regions that exists today. The system cools the temperature inside the greenhouse to 7 ° C.

How it works? Water is supplied to the air in the form of a pressurized mist through special high-pressure nozzles. The water mist immediately evaporates and removes heat energy from the air, so that the air temperature decreases and the humidity increases.

The high pressure mist system helps the plants stay in balance with the water supply of the root system and the rate of evaporation through the leaves - the stomata remain more open. This increases crop productivity and reduces irrigation and energy costs.

By creating the ideal greenhouse climate you can help your plants grow stress-free and produce great yields!

Growing delicious tomatoes with LED lighting
18.06.2021

Getting really tasty vegetables is one of the most important growing goals.

 Research shows that tomatoes grown under LED lighting taste great. Thanks to the higher light intensity, with the help of LEDs, conditions are created to further improve the taste.

The choice of tomato variety plays an important role, but the growing conditions that affect taste and aroma are equally important, since consumers make their choice based on these parameters.

How do you find the right spectrum for additional lighting?

There are several spectra that can have a beneficial effect on the taste of tomatoes. For example, blue light is known to have an interesting effect. Increased blue light levels have been shown to have a positive effect on taste and smell. Another light spectrum is far red, which can enhance the flavor of the fruit. However, distant red can cause undesirable effects such as increased stem length. In doing so, blue light can do the opposite and shorten the length of the stem. By combining blue and far red, you can get the best of both spectra: improved flavor without extra plant pulling.

So, as a result of studies that compared various combinations of spectra, the most delicious tomatoes turned out to be using the standard red, blue and blue spectrum, optimized for tomatoes.

In general, LEDs can provide more hours of illumination and higher light intensity in the greenhouse, as well as help to achieve a higher yield.

Growing on hanging trays
11.06.2021

Different equipment is used to grow different plants with the help of hydroponics in the greenhouse.

The use of hanging trays allows you to create the most comfortable microclimate for plants in the greenhouse. Vegetables are grown on hanging trays: tomatoes, cucumbers, sweet peppers, eggplants, etc., as well as strawberries. This method is most common in Europe, because it uses automated placement and collection.

Suspended trays are deployed individually along the length of the greenhouse using a special molding machine. This is done in order to minimize the number of joints. The minimum quantity or even absence of connecting seams allows to proceed "Not drunk" by plants drainage water without obstacles. In a closed loop system, this water is purified and reused for irrigation. Thus, the cost of water and mineral fertilizers is reduced.

Note that previously the same trays for growing vegetables were placed on stands. Today, steel supports for trays are used mainly for growing gerberas and roses.

Why can't you grow tomatoes and cucumbers together?
28.05.2021

Can crops such as tomatoes and cucumbers be grown together? As a rule, these two crops are not advised to grow side by side, and there are reasons for this. This is due to different crop requirements for humidity, temperature and care, as well as problems with pollination.

Cucumbers love moist air, so water them every other day or every day. And if it is very hot, it will not hurt to moisten not only the plants themselves, but also the paths and walls of the greenhouse. And these vegetables love when they arrange a real bath: for an hour close the doors and windows, water the whole ground and plantings with warm water and create a steam effect. Cucumbers then grow like yeast. Overdried soil delays growth, cucumber gains weight due to lack of moisture and grows bitter, ugly and thick as a barrel. Due to the lack of moisture, female flowers and ovaries turn yellow and fall off prematurely.

Tomatoes, on the other hand, too humid air is useless. They are easier to tolerate heat and lack of moisture in the soil, as well as peppers and eggplants. At high humidity suffer from various fungal and bacterial diseases: gray rot, brown spot, late blight and other unpleasant diseases. Therefore, in warm weather in a greenhouse with tomatoes, it is desirable to leave open a small window, even at night. At high humidity, the tomatoes stick together pollen, and the flowers are not pollinated. The same thing happens when there is no air movement, ie the plants do not sway. Therefore, in the summer in tomato greenhouses, you can periodically arrange drafts, opening in addition to the windows at the ends of the greenhouse and both doors.

Another reason is that tomatoes in greenhouses are pollinated by bumblebees, so if bumblebees start pollinating cucumbers, we get non-standard products that may be unfit for sale.

We hope you found the information useful.

Greenhouse convertible, have you heard of this?
21.05.2021

The convertible greenhouse has been designed for growers who want optimal ventilation and light penetration. And it got such an interesting name thanks to a special roof, which is mounted on an adapted Venlo supporting structure. This gives manufacturers a full range of options for adjusting the climate to the desired level.

From the outside, when the ventilation windows are closed, the convertible greenhouse looks just like the Venlo. However, the difference is easy to spot as soon as the ventilation windows are opened. The aluminum roof can be opened FULLY.

Instead of being ventilated from the side of the ridge, the windows open from hinges on the tray. The main advantage of the convertible greenhouse is that specific plants can be conditioned and hardened by exposing them to external weather conditions. When the windows are opened, the climate in the greenhouse is fully consistent with the external one.

Wide-range greenhouses
16.04.2021

There are several types of industrial greenhouses. One of them is wide-span greenhouses.

Structurally, a wide-span greenhouse differs from Venlo in its span width, roof and ventilation. The span can be up to 12 m, while it has one skate for the entire width of the span. A wider span creates more air buffer, resulting in a more pleasant climate. These greenhouses are used for garden centers and other architectural masterpieces.

It is worth noting the main disadvantage of this type - it is much larger and heavier than the Venlo greenhouse.

The advantage of this kind of greenhouse is the minimum of shade. This design offers almost endless possibilities for realizing specific wishes for greater light and air penetration. Ventilation with solid windows ensures maximum fresh air intake. One-way or two-way opening of windows is especially suitable for mosquito nets.

The wide span greenhouse is the ideal solution for many types of crops. Large column spacing provides more space for plants and automation.

How to grow pepper seedlings
09.04.2021

Pepper is a source of vitamins and useful elements. A crispy vegetable with a rich taste and bright colors will perfectly complement your plate. At the same time, pepper is a rather capricious culture. To grow peppers in a seedling way, you have to work a little.

The time of sowing pepper seeds depends on the conditions and place of planting seedlings. In general, we recommend using the following rule: sowing is carried out 60 days before disembarking to a permanent place, if a pick is carried out, and 50 days without it.

The preparation of the correct and high-quality soil is one of the important stages in the cultivation of any crop. It is recommended to sow peppers for seedlings in loose and light soil. You can use ready-made seedling mixes or you can buy them at any garden store.

Usually, seed producers decontaminate them even before the start of sales, therefore, when buying professional seeds, decontamination can be skipped.

Pepper does not tolerate picking well, so it is most convenient to sow directly into separate pots. Place the seed to a depth of 1-2 cm and sprinkle with a layer of soil, press lightly. Then the containers with seeds are moistened and covered with foil or glass. When the seeds begin to hatch, the film must be removed and transferred to a warm and bright room. If necessary, install additional lighting lamps.

Pepper seedlings need a temperature of at least 20 ° C. And for the plants to grow quickly, provide them with 24-25 ° С. But it is worth remembering that growing too fast can weaken the stem and leaves.

Before transplanting seedlings to a permanent place, the plants must be hardened. It usually takes about two weeks to quench. At the time of hardening, the seedlings should be 20–25 cm in height.

On the first day, open the window where the plants are for 1 hour. Increase the duration of the procedure up to 8 hours every day. Immediately before planting, the plants are taken out on the porch, and 1 day before transplanting - overnight, protecting from too cold air. During the period when you transplant seedlings to a permanent place, the average daily air temperature should be 15 ° C.

Well, that's all, the seedlings are ready to be transplanted to a permanent place!
