1, fertilization irrigation: Kyoho grape has a great demand for fertilizer and water, and its requirements for nitrogen, phosphorus and potassium fertilizer are more stringent. The experiment shows that 100 kg berries need 1:0.3: 1 kg nitrogen, phosphorus and potassium fertilizer. Therefore, proper application of organic fertilizer and foliar fertilizer in winter can effectively improve fruit quality. However, it should be noted that Kyoho grape grows vigorously, and the amount of nitrogen fertilizer should be paid attention to during the fast growth period. If the nitrogen fertilizer is applied excessively, it will lead to the phenomenon of falling flowers and fruits in vain, and it will also affect the yield in the next year. During this period, some phosphorus and potassium fertilizers should be appropriately increased. Ensure that Kyoho grapes have enough water from germination to the later stage of berry coloring. Irrigation should be stopped half a month before harvest.

2, plastic pruning: grapes must be pruned, otherwise the plant is too long and grows too fast, which will make the fruit grow poorly. Plastic surgery can be cultivated with hedgerows and T-frames, with no more than three main vines per plant. When pruning in winter, medium and long branches should be pruned, and each square should have about 7 fruiting mother branches, staggered up and down to ensure the permeability between branches and vines. New shoots should be picked in time, and at least one leaf should be left on the secondary branches, and coring should be repeated.

3. Thinning flowers and fruits: Many people find that the quality of Kyoho grapes is not very good when they are finally harvested, which reduces the commercial value of grapes. In fact, the main reason for the decline in quality is high output. Properly control the yield, and the yield per mu should be around 2000 kg. Adjust the tree potential by thinning flowers and fruits, keep the tree potential moderate and achieve stable yield distribution. After the fruit expands, it is necessary to remove bad fruit particles such as small particles, diseased particles and cracked fruits in time.

4. Fruit bagging: Now the technology of fruit bagging has become more and more mature, because fruit bagging can well reduce the occurrence of diseases and ensure that fruits are not harmed by external factors such as pesticides, birds and bees. It can enhance the luster of the peel, keep the fruit bright and improve the quality. Bagging can be started after the grapes are physically dropped. When the grapes grow to the size of soybeans, spray thiophanate-methyl after thinning flowers and fruits. When the medicine is dry, it can be bagged and unpacked half a month before harvesting.
