How to plant Jufeng grape

Originally grown in Japan, Kyoho grapes were introduced to China in the 1990s. Unlike other grapes, Kyoho grapes are difficult to manage. Because of its serious flower failure, fruit setting rate is also low. However, it has a high value, Kyoho grape has sufficient water, sugar content is also high, contains a strong oxidant, can effectively anti-aging, clear the body of free matrix. Although it is difficult to manage, there is still a large planting area in our country. Below, I will bring you about the management of Kyoho grape.

1. Fertilization and irrigation

Kyoho grape has a great demand for fertilizer and water, and the requirements for nitrogen, phosphorus and potassium fertilizer are even stricter. Experiments have shown that 100 kilograms of berries need 1:0.3:1 kg of 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 grapes grow more vigorously, and attention should be paid to the amount of nitrogen fertilizer during the rapid growth period. If nitrogen fertilizer is used excessively, it will lead to excessive growth of plants and drop flowers and fruits, and will also affect the yield of the next year. This period should be appropriate to add some phosphorus and potassium fertilizer. In the Kyoho grape after germination to the late berry coloring period to ensure adequate moisture grape. Irrigation should be stopped half a month before harvest.

2. Shaping and pruning

Grapes must be pruned, otherwise the plants are too long and grow too fast, which will make the fruit grow poorly. The shaping can be cultivated by hedge frame and T-shaped frame, and each main vine shall not exceed 3. During winter pruning, the medium and long shoots should be pruned. There should be about seven fruiting mother branches in each square, and they need to be staggered up and down to ensure the permeability between branches and vines. The new shoots should be picked in time, and at least one leaf should be kept on the secondary shoots for repeated picking.

3. Thinning flowers and fruits

Many people found that the quality of Kyoho grapes was not very good when they were finally harvested, which reduced the commodity value of grapes. In fact, the main reason for the decrease in quality was because the yield was too high. To properly control the yield, the yield per mu should be about 2000 kg, adjust its tree potential through thinning flowers and fruits, maintain the moderation of tree potential, in order to achieve the goal of stable yield distribution, after fruit expansion, it is necessary to timely eliminate small, diseased and cracked fruit and other bad fruit grains.

4. Fruit bagging

Now fruit bagging technology has become more and more mature, because fruit bagging can reduce the incidence of disease, but also to ensure that the fruit is not affected by pesticides, birds and bees and other external factors. It can enhance the luster of the peel, keep the bright color of the fruit, improve the quality, and start bagging after the physiological fruit drop of the grape. When the grapes are about the size of soybeans, they are thinned and then sprayed with thiophanate-methyl. After the medicine is dried, bagging can be started, and the bagging can be removed half a month before harvest.

The above is on the Kyoho grape planting method, planting Kyoho grape can not be planted in accordance with ordinary grapes. Because Kyoho grape flower abortion is more serious, and fruit set rate is low, fruit cracking and fruit drop phenomenon are more serious. Therefore, we must master a correct breeding method in order to achieve the goal of high yield and high yield, nor can we not remove the fruits on the plants for high yield.
