For the standard maturation of medium-ripening grapes, 110 days a year, with average daily temperatures of over 10o C are needed. The plant’s demand for warmth is set by the entire sum of temperatures throughout the period from bud blossoming to berry ripening.
At the middle of Russia, the sum of active temperatures in summer time hardly reaches 2190 C. Therefore, most forms need over 110 times for full adulthood.
Growing grapes is interesting because it requires the gardener to constantly perform his own research and analytic work. Even when the winegrower is totally armed with theoretical knowledge, creativity is demanded of him. The evolution of the blossom is subject to particular rules, but in every area, literally in every backyard, even more so in greenhouses, exactly the very same plants develop otherwise, requiring human working techniques. Take, by way of example, the main system.
In arid places, on clay, stony and rubbly lands, the root penetrates to a depth of about 4 m. at which the subsoil is continually moist, the root lobes expand broad and are located to a thickness of up to 1 m.
The biological phases of this plant must also be taken into account. To understand the vineyard and plan work, you will need to have an concept of the yearly cycle of vine development.
One of the many agricultural methods, the trench approach is considered preferable. With this procedure, nutrients are placed on the soil at highest area and depth. The roots of the grapes are provided with masterfasada.ru fertile soil for 30-50 years – practically the entire life cycle.
Planting sequence:
- The best soil layers are eliminated and put individually.
- A trench about 60 cm deep is dug.
- In the very bottom place a drainage layer of crushed stone – approximately 10 cm thick.
- About 1/3 of the depth in a hole set a nutrient substrate – peat (3 components ), sand (2 parts) and subsoil loam (7 components ).
- Vine cuttings are planted.
- Fill in the remaining substrate.
Grape plants find themselves in a nutritious atmosphere. Their root system may develop downward and sideways, and from above it is protected with a warm loose cushion.

A broad range of grapes is available in our store. Among the varieties of mythical, widely known and the finest of modern you can readily pick the one that you want. For growing in greenhouses suitable super ancient and ancient types of grapes, with a maturity period of the berries out of 90 to 120 days. Design features of a greenhouse
1. Cellular polycarbonate with a thickness of 6 mm was selected as the material to cover the greenhouse for grapes. Now this material is a pioneer in the production of greenhouses for any purpose. It is not prickly, fire resistant, simple to handle with all the simplest tools. Polycarbonate (hereinafter PKB) retains heat well – on a bright winter the air in a greenhouse warms around zero temperatures and then it slowly declines during the evening .
