Climatic conditions of various regions do not always allow to grow thermal-loving cultures, especially such as grapes. Low average temperatures are affected here in the warm season, as well as the insufficient duration of the daylight. In this case, it is recommended to use modern techniques that allow you to grow a southern plant in greenhouses. Due to the many years of practice of experimental breeders, greenhouse varieties are not inferior to traditional in high-quality characteristics.
What varieties will fit?
Perfect technology allows grapes to grow on any household plot using a greenhouse for this purpose. Showing patience and applying some knowledge, you can achieve a high result in obtaining a rich crop from the chosen culture. Closed designs will allow not only to increase the length of the season, the leaf of the plant from spring frosts, but also protect them from such unpleasant impacts as randoms in the form of a hail.
Before landing grapes in a greenhouse, you should choose the most appropriate wishes of the customer. Most often, such attempts are made in zones with a temperate climate, where the following varieties have proven well:
- “Early Northern”;
- “Russian cigrix”;
- “Moscow Sustainable”.
Polycarbonate greenhouses will be an excellent solution that allows you to plant the presented varieties at the beginning of spring. Each of the new varieties is growing superbly and develops in a closed space with proper care in the required temperature mode and sufficient illumination.
For the landing of a vine primarily prepare the soil. Here it is best to use a compute mixture prepared by a specific recipe.
- A bit of superphosphate and wood ash enriched with potassium add to portion.
- The resulting substance is bred 50/50 with soil from the greenhouse.
- Landing holes are digging to a depth of 0.5 m, filled with a compost mixture, and plant seedlings.
- When landing, it is important to carefully straighten the root system, place a seedling into a moistened well, press it with soil, and plenty.
The landing of cuttings in the greenhouse can already be produced in the first numbers of March. During this period, the Light Day continues sufficient time for plants, and the external average temperature air temperature does not reach dangerous values. In greenhouse equipment, it is important to include supporting frames for which the developing vine will be cling.
It should be remembered that the bunch of grapes must be kept in suspended to avoid premature rotting.
To obtain a high-quality harvest in greenhouse conditions, the plants should be obtained. The most important condition that allows the plant in a timely manner to move to the next phase of development, without reducing growth rates, the temperature regime is considered.
This means that the temperature of the air in the greenhouse must comply with certain standards on each segment of the plant development. There are frameworks for each cycle to which include:
- renal development period;
- the time of active growth of the vine;
- flowering period;
- stage of fruit formation;
- Ripening period.
For each intermediate stage there are optimal temperature frames that allow the plant to feel comfortable. Too high or too low temperature is equally poorly affected by growing culture. The result may be the late harvest, requiring additional costs. This means that it is important to the greenhouse not only to insulate, but also to equip the dimming in the form of a special grid. This precaution will not allow the sunshine to overly warm the inner space.
In addition, an effective ventilation system should be provided, which allows to aircading at high day temperatures. For this purpose, opening flaps are used to fill the space of fresh air naturally. This procedure will allow not only to supply plants with the necessary amount of oxygen, but also comply with the required temperature regime.
One of the important stages of the care of grapes is to be student. The procedure comes down to the timely removal of underdeveloped processes, patients with leaves and not polished inflorescences. Thus, the root system will not spend the valuable energy resource for the maintenance of useless elements. On the other hand, all the forces of the plant will be aimed at the development of healthy processes and full-fledged fruits.
The period of flowering grapes, as a rule, comes in the second half of May. Most of the greenhouse varieties are located to self-pollution, but some cultures still need extraneous assistance. This moment must be specified at the time of purchase. Pulling grape color is quite simple: it is necessary to make a methodically shake branches with inflorescences.
Actively developing vine can fight back from an artificial support, in this case it needs to be fixed forcibly. Fancy shoots are subject to cutting, they are shortened to the position of the position of the fifth sheet. If these are second-order steps, they can be shortened before the location of the first sheet. With abundant fruiting green bunches of grapes should also be switched. Internal formations are subject to removal, poorly adapted to full-fledged development due to unsuccessful location.
TOWhen the harvest is assembled, and the leaf has sunk, it is time for autumn trimming. During this period, all the long processes are removed before the location of the first kidney. At the same time, the central stems are shortened by 2/3 of length. The vine is discharged from the support, spread over the soil and is covered with hay, straw or sawdust, so that in winter it does not die from frost.
If the roof in the greenhouse has a removable design, it is removed for winter. Sheltered grapes perfectly winter under the snow.
