Rules for growing grapes in a polycarbonate greenhouse
Breeders are introducing new varieties of fruit for cultivation in cold regions. A line of such species has also been created for the southern berry. But in Siberia or in the Urals, it is not always possible to grow berries on open ground, so growing grapes in a greenhouse is necessary. Polycarbonate is considered the best material.
Rules for growing grapes in a greenhouse
Growing grapes in a greenhouse (especially in cold regions) is beneficial for several reasons:
- simplifies care in a cold climate;
- allows you not to limit yourself in choosing varieties;
- increases productivity;
- solves the problem of sheltering vines for the winter.
The greenhouse for growing grapes from polycarbonate is heavy-duty, durable, has a unique light transmission and maintains the required temperature in the greenhouse.
A polycarbonate greenhouse has the following characteristics:
- Easy to use.
- It keeps the temperature well, which is good for winter, but in summer the temperature reaches 50 ℃. This makes us think about the cooling system.
- It is easier to provide a ventilation system, because the sheets of material are small.
- The material is fireproof.
Parameters and requirements for the greenhouse
Growing grapes in a greenhouse, you need to take care of it. You can facilitate maintenance by laying down some parameters for the greenhouse at the planning and assembly stage:
- ample space for plants;
- ventilation in the corners of the structure;
- thermal insulation of plants in the winter;
- the ability of the structure to withstand a layer of snow (so as not to dismantle the greenhouse in winter).
To facilitate the maintenance and care of the plant, it is necessary that the greenhouse have the following features:
- Extra ventilation for hot summers.
- The ability to heat the culture at low temperature.
- Ways to adjust the light (additional light sources).
- The mobility of the structure (the ability to assemble and disassemble it).
- Early landing in the ground cuttings.
Plant health depends on the quality of the greenhouse
Do-it-yourself construction is not easy, it requires certain building skills and knowledge. Some tips to simplify the construction of a greenhouse for grapes:
- Think in advance about the location of the bushes. Draw a diagram, calculate the footage.
- Choose the right place for the greenhouse. It is located on the south side of the site, the soil should not be marshy. Make sure that other structures do not create an unnecessary shadow.
- Prepare materials and tools in advance.
- The optimal shape of the roof is the hemisphere. It allows you to maximize the use of space and does not collapse in the winter under the snow.
A properly built greenhouse will allow you to grow late varieties not only in the south, but also in cold climates.
Planting a crop in a greenhouse
Also follow the rules for planting and caring for grapes in the greenhouse. First you need to plant several bushes of grapes in a greenhouse, choose early varieties.
First they prepare the soil: greenhouse soil is mixed with superphosphate and ash. Bushes should be planted at a distance of 70 cm from each other, and at a distance of at least 50 cm from the walls of the greenhouse. Landing holes are dug up to 40 cm deep. Landing technology using other techniques involves the creation of drainage.
Plant cuttings in the spring in a warm earth. The greenhouse should be ready for planting time. If sudden freezing starts, a heating system will come in handy. When the vine takes root, standard care is carried out for it: formation, watering, top dressing.
In the greenhouse, make sure that the plants do not burn out from excessive temperature and the scorching sun. For grapes, the following temperature regime is suitable:
- When the buds begin to bloom from 10 ℃ to 40 ℃ during the day, from 8 ℃ to 10 ℃ at night.
- When shoots grow and the culture blooms 24-26 ℃ in the afternoon, 14-16 ℃ at night.
- During ripening during the day 28-30 ℃, at night 18-20 ℃.
- In this case, the soil temperature is not less than 20-25 -25.
They also treat pests and infections that appear in the culture. But their number with proper care will be significantly less than in the open ground.
It is recommended to cover the vine for the winter with dry leaves (to avoid aging) or a perforated film. It is allowed to cover with coniferous leaves, sawdust. In addition, it is not necessary to cover the vine with something in the greenhouse - the walls and the roof with a layer of snow will maintain the optimal temperature regime.
If the planting of the first test bushes was successful, plant the greenhouse with the desired varieties next year. Growing grapes in greenhouses increases the productivity of early varieties, allows you to worry less about weather conditions.
With proper care, grapes in a greenhouse will grow even in Siberia and the Urals. In well-built greenhouses, it is possible to grow vineyards from late southern varieties. When leaving, observe the rules: water, form a bush, process from pests.
