Detailed Explanation of Key Points of Summer Black Grape Cultivation Techniques
Summer Black grape is a derivative of Kyoho grape. Compared with Kyoho grape, Summer Black grape ripens earlier, has no seeds and contains a very high sugar content. Its flesh is firm and tight, and it is welcomed by many people, so there is now a certain planting area in our country, with good economic benefits. So how should Summer Black grapes be cultivated? Today the editor brings you the cultivation techniques for Summer Black grapes. Let's take a look below!
1. Seed and soil selection
Summer Black grapes have many varieties. When selecting seeds, we should choose suitable varieties according to factors such as local weather conditions. After selecting the varieties, choose soil with convenient transportation, sufficient water sources, deep soil layers and good drainage and irrigation for planting. Then do the land preparation work in the autumn of the year before planting, break up and level the soil finely, and improve the soil permeability. Then apply sufficient base fertilizer, deeply plow the soil once, and fully mix the fertilizer with the soil. Finally, control the planting density well, dig the planting trenches, and prepare for planting.
2. Young tree management
After planting, do a good job in young tree management. When the young trees grow their eighth true leaf, do the topdressing work well, applying fertilizer about once every half a month. In the early stage, fertilization is mainly nitrogen fertilizer, and then during August-September, change the fertilizer to phosphorus and potassium fertilizer. After planting, do the trellising work well, set up supports beside the seedlings, and pull several wires through the supports. When the new shoots grow to about 55 cm, do the vine tying work well. Finally, during the young tree stage, also pay attention to the prevention and control of pests and diseases, regularly spray the plants for disinfection, and improve the growth ability of Summer Black grapes.
3. Shaping and pruning
About half a month after all the leaves have fallen in winter, carry out a winter pruning. The main pruning target is the fruiting branches of the current year, retaining 3 buds for short cutting, and thinning out excess branches. When pruning, prune inward to prevent the fruiting position from growing outward. Then cut off undesirable branches such as overly long, overly dense, pest- and disease-affected branches, improve the cold resistance of Summer Black grape plants, and help them overwinter. Then in summer, also do various tasks such as bud removal, pinching and vine tying well, improve permeability, promote the growth of Summer Black grapes, and increase yield.
4. Flower and fruit management
Summer Black grapes have relatively strong growth ability. Generally, new shoots will have more than two inflorescences. When planting, in order to improve yield and grape quality, it is enough to retain one inflorescence per new shoot. Excess inflorescences should be thinned out. If there are too many inflorescences, nutrient consumption will be large and the fruit set rate will be high, which will instead affect yield. Therefore, we should timely thin out inflorescences that grow weakly and poorly. Then, according to tree vigor and fruit load, do the fruit thinning work well to prevent exceeding the bearing range of the fruit tree and affecting the growth of Summer Black grapes.
The above is a brief introduction to Summer Black grape cultivation techniques. Summer Black grapes are relatively easy to grow. However, we also need to do management work well and strengthen management in all aspects to ensure yield. That is all for today's introduction. This article is for reference only.
