Planting and Management techniques of Xiahei Grape

Xiahei grape is one of the grape varieties, it is derived from Jufeng grape, but it ripens earlier and tastes better than Jufeng grape, has no stone and high sugar content, so it is very popular. With the increase of its market demand, many growers see its income. At present, there is a certain planting area in our country, so how to plant summer black grapes? Let's take a look.

1. Establishment and planting of the garden

Xiahei grape plantation should choose flat and open terrain, ensure a good drainage system, and choose soil rich in organic matter, fertile and loose, and good permeability. In planting, it is necessary to deep plough the soil, dig and plant snow at a distance of 3 meters, and apply rotten farm manure as base fertilizer in the ditch, generally 4000 kilograms per mu, with an appropriate amount of chemical fertilizer. After fertilization, cover the soil and irrigate, let the soil sink naturally, and fill the ditch after the water is dry. Select high-quality seedlings for cultivation, the planting depth should be the same as the depth of the seedlings in the nursery, too deep or too shallow are not conducive to its growth.

2. Shaping and pruning

After planting, it is necessary to fight and draw the vine in time, and at the same time do a good job of summer shearing, which includes wiping buds, fixing tips, coring, removing tendrils and binding vines. Wiping buds are generally carried out after the present order, generally leaving 2-3 buds per branch, erasing deformed buds, weak buds, and selecting strong buds with normal growth; fixing shoots are carried out before flowering, leaving new shoots qualified for moderate growth every 20 centimeters, and timely thinning of new shoots that are thin, too dense and improperly positioned; coring is carried out before flowering, coring should be paid attention to, and large leaves are generally selected for coring. Timely removal of tendrils can save nutrients and is conducive to fruit growth. when the new shoot grows to 50 cm, tie the vine in time to avoid breaking. In addition, winter pruning should be carried out, which usually continues half a month after falling leaves, and most of them are trimmed with short shoots. As a result, 2-3 buds are generally cut short, and the rest are all thinned. At the same time, diseased and dead branches, weak branches, and over-dense branches are also trimmed.

3. Flower and fruit management

Xiahei grape grows vigorously and has good flower bud differentiation, and most of the new shoots have more than 2 inflorescences, but in order to save nutrients and improve fruit quality, it is necessary to thinning flowers. Generally, only 1-2 inflorescences are left on new shoots, and the rest should be thinned in time. At the same time, inflorescences that are too small, stunted and damaged by diseases and insect pests should be removed. At the same time, in order to improve the fruit setting rate, it is necessary to take timely measures to protect the fruit, generally spraying gibberellin 4-10 days after the fruit is set. When the size of the fruit is clear, the fruit should be thinned in time, too small, too large, deformed, dense, diseases and insect pests and stunted fruit, save nutrients and promote fruit growth.

4. Fertilizer and water management

Summer black grape is a variety that needs a large amount of fertilizer. in order to ensure high yield every year, we should pay attention to the use of organic fertilizer in fertilization, so as to improve fruit quality and obtain higher economic benefits. The annual fertilization is composed of base fertilizer, budding fertilizer, pre-flowering fertilizer, fruit expansion fertilizer, color-changing fertilizer and fruit-picking fertilizer. The whole growing period of Xiahei grape can be watered once before sprouting and after freezing, and the rest of the time should pay attention to the amount of water, especially in the flowering and fruit stage, so as not to reduce the fruit quality.
