How to Plant Black Grapes in Summer
Today's tip on life experience covers how to plant black grapes in summer, focusing on green plant care. Let's introduce the following to everyone.
How to Plant Black Grapes in Summer
Black grapes are one of the grape varieties. They originate from Kyoho grapes but mature earlier, have a better taste, are seedless, and have high sugar content, making them very popular. With the increasing market demand, many growers have seen its profitability. Currently, there is a certain planting area in our country. So, how should black grapes be planted in summer? Let's find out.
Garden Construction and Planting
Planting black grapes in summer should choose flat and open terrain to ensure a good drainage system, selecting soil that is rich in organic matter, fertile, loose, and has good water permeability. During the planting process, deep tillage should be carried out in the soil, digging a trench every 3 meters and applying ripe farm manure as a base fertilizer in the trench. Generally, 4000 kilograms per mu are applied, supplemented with an appropriate amount of chemical fertilizers. After fertilizing, cover the soil with water, allowing the soil to settle naturally, and fill the trench after the water dries. High-quality seedlings should be selected for cultivation, with the planting depth being the same as that in the nursery. Planting too deep or too shallow is not conducive to their growth.
Shaping and Pruning
After planting, timely introduction and summer pruning should be done. Summer pruning includes wiping buds, setting buds, pinching, removing tendrils, and binding vines. Generally, 2-3 buds are left per branch, removing abnormal and weak buds and selecting strong normal buds; the first step is to leave a moderately growing new shoot every 20 centimeters, promptly removing weak, dense, and improperly positioned ones; picking should be done before flowering and attention should be paid to the picking site. Generally, large leaves should be selected for pinching; timely removal of tendrils can save nutrients and is beneficial for fruit growth. When new shoots grow to 50 centimeters, they should be promptly tied with tendrils to prevent breaking. Additionally, winter pruning should be carried out. Generally, it should continue about half a month after defoliation. Short hair is usually used for pruning. The 2-3 buds of the fruiting branches are usually pruned short, and the rest are retained. At the same time, pruning should be done on withered, weak, and dense branches.
Flower and Fruit Management
Most new shoots have more than 2 inflorescences, but to conserve nutrients and improve fruit quality, it is necessary to thin the flowers. Generally, only 1-2 inflorescences are left on the new shoot, and the rest should be removed promptly. At the same time, inflorescences that are too small, underdeveloped, or severely affected by diseases and pests should be eliminated. Also, measures to protect the fruit should be taken in a timely manner to improve the fruit setting rate. Generally, apply gibberellin 4-10 days after flowering, and promptly after fruit setting. When the fruit size is clear, thinning should be done promptly, such as removing small, large, misshapen, dense, diseased, and underdeveloped fruit particles to save nutrients and promote fruit growth.
Fertilizer and Water Management
Black grapes in summer require a large amount of fertilizer. To ensure high yields every year, organic fertilizers should be used when fertilizing to improve fruit quality and achieve higher economic benefits. Annual fertilization consists of base fertilizer, bud promotion fertilizer, pre-flowering fertilizer, fruit expansion fertilizer, color change fertilizer, and post-harvest fertilizer. During the whole growing period of black grapes in summer, large amounts of water should be applied before germination and after freezing, and attention should be paid to the amount of water during rest periods, especially during the flowering and fruiting stages, to avoid reducing fruit quality.
