Cultivation Techniques of Summer Black Grape

Xiahei grape is a derivative of Jufeng grape. compared with Jufeng grape, Xiahei grape ripens earlier, has no stone and has a very high sugar content. The meat is hard and tight, which is welcomed by many people, so our country also has a part of the planting area, which has better economic benefits. So how to grow summer black grapes? Today, the editor brings you the planting technology of summer black grape. let's take a look at it.

1. Selection of species and soil

There are many varieties of Xiahei grape, so we should choose the suitable variety according to the local weather conditions and other factors. After selecting the variety, we should choose the soil with convenient transportation, adequate water source, deep soil layer and good drainage and irrigation to plant. Then do a good job of soil preparation in the autumn of the year before planting to break up the soil and improve its permeability. Then apply sufficient base fertilizer, turn the soil deep again, and fully mix the fertilizer with the soil. Finally, control the planting density and dig the planting ditch to prepare for planting.

2. Management of young trees

After planting, it is necessary to do a good job in the management of young trees, topdressing once every half a month or so when the saplings grow the eighth true leaf. Nitrogen fertilizer was the main fertilizer in the early stage, and then the fertilizer was converted into phosphorus and potassium fertilizer from August to September. It is necessary to do a good job in setting up the frame after planting, erect a good support next to the seedlings, pull a few wires in the support, and do a good job of binding vines when the new tip grows to about 55 centimeters. Finally, in the young tree stage, we should also pay attention to the prevention and control of diseases and insect pests, and spray disinfect the plants regularly to improve the growth ability of Xiahei grape.

3. Shaping and pruning

After about half a month after all the leaves have fallen in winter, an overwintering pruning will be carried out. The main pruning objects are the fruiting branches of the same year, and three buds are retained for truncation to remove the redundant branches. Trim inward when pruning to prevent the resulting area from growing outward. Then it is necessary to cut off bad branches such as too long and too dense, diseases and insect pests, so as to improve the cold resistance of summer black grape plants and help them survive the winter. Then we also need to do a good job of wiping buds, picking hearts and binding vines in summer to improve permeability, promote the growth of summer black grapes and increase production.

4. Flower and fruit management

The growth ability of summer black grape is relatively strong, generally new shoots will have more than two inflorescences. When we plant, in order to improve the yield and the quality of grapes, we can keep one inflorescence per shoot. To remove too many inflorescences, if there are too many inflorescences, high nutrition consumption and high fruit setting rate will also affect the yield. Therefore, we should remove the inflorescences that are too weak and poorly grown in time. Then it is necessary to do a good job of fruit thinning according to the tree potential and fruit quantity, so as to prevent it from exceeding the bearing range of fruit trees and affecting the growth of summer black grapes.

The above is a brief introduction of summer black grape planting technology, summer black grape is relatively easy to grow. However, we also need to do a good job in management and strengthen management in all aspects in order to ensure output. That's all for today's introduction. This article is for reference only.
