How to plant the latest Jufeng grape

Jufeng grape, originally produced in Japan, was introduced to China in the 1990s. Unlike other grapes, Jufeng grape is more difficult to manage. Because its flower failure is very serious, the fruit setting rate is also low. But it has high value, Jufeng grape has sufficient water and high sugar content, and contains a powerful oxidant, which can effectively anti-aging and remove the free matrix in the human body. Although it is difficult to manage, there is still a large planting area in our country. Next, I will bring you about the management of Jufeng grape.

1. Fertilization and irrigation

Jufeng grape has a great demand for fertilizer and water, and the requirement for nitrogen, phosphorus and potassium fertilizer is even more stringent. Some experiments show that one hundred kilograms of berries need 1 kilogram of nitrogen, phosphorus and potassium fertilizer. Therefore, the proper application of organic fertilizer and foliar fertilizer in winter can effectively improve the fruit quality. However, it should be noted that the growth of Jufeng grape is more prosperous, in the rapid growth period, we should pay attention to the amount of nitrogen fertilizer. If the nitrogen fertilizer is used too much, it will lead to the phenomenon of falling flowers and fruits, and will also affect the yield of the next year. During this period, some phosphate and potash fertilizer should be increased appropriately. It is necessary to ensure sufficient moisture in the berry coloring period from the sprouting to the later stage of Jufeng grape. Irrigation should be stopped half a month before harvest.

2. Shaping and pruning

Grapes must be shaped and pruned, otherwise the plants are too long and grow too fast, which will lead to poor fruit growth. Plastic surgery can be cultivated with hedges and T-shaped shelves, with no more than 3 main vines per plant. The middle and long shoots should be trimmed when cutting in winter, and 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 the branches and vines, pick the new shoots in time, and keep at least one leaf on the secondary shoots for repeated heart picking.

3. Thinning flowers and fruits

Many people in the final harvest of Jufeng grape found that the quality of Jufeng grape is not very good, reducing the commercial value of the grape, in fact, the main reason for the decline in quality is due to high yield. In order to properly control the yield, the yield per mu should be about 2000 kg. Adjust the tree potential by thinning flowers and fruits to maintain the moderation of the tree potential, in order to achieve a stable distribution of production. After the fruit is enlarged, the bad fruit grains such as small grains, diseased grains and split fruits should be removed in time.

4. Fruit bagging

Now the technology of fruit bagging has become more and more mature, because fruit bagging can not only reduce the incidence of diseases, but also ensure that the fruit will not be harmed by external factors such as pesticides, birds and bees. It can enhance the glossiness of the pericarp, keep the fruit bright, improve the quality, and begin bagging after the physiological fruit drop of the grape. When the grapes grow to the size of soybean grains, thinning flowers and fruits and then spraying methyl topiramate. When the medicine is dry, the bagging can be started, and the bagging can be removed half a month before harvest.

The above is about the planting method of Jufeng grape, the planting of Jufeng grape can not be planted according to ordinary grapes. Because the flower failure of Jufeng grape is more serious, and the fruit setting rate is low, the phenomenon of fruit cracking and fruit drop is more serious. Therefore, we should master a correct culture method in order to achieve the goal of high yield and high yield, and we can not remove the fruit on the plant for the sake of high yield.
