steps of planting vines:
1. Fertilizer and water management
Re-apply base fertilizer: during the growth period of grapes, a lot of nutrients are consumed in the body, so after the fruits are harvested, they should be fertilized in time to supplement nutrients, restore tree vigor and continue energy. The base fertilizer is mainly organic fertilizer, and the best fertilization time is from fruit picking to defoliation. At this time, the cut roots can heal quickly and germinate a large number of absorbed roots, which improves the absorption rate of fertilizer.
Skillful topdressing: topdressing 3-4 times a year. For varieties with easy fruit setting, topdressing nitrogen fertilizer before and after germination. In addition, spraying "Zhuangguodiling" with foliar fertilizer before flowering, young fruit stage and fruit expansion stage can not only prevent the phenomenon of falling flowers and fruits caused by bad weather conditions, but also make the nutrient transport conduit of grapes thicker, stronger pedicels and stronger fruits, and improve the fruit expansion speed and color.
second, the management of flowers and fruits
thinning the redundant inflorescences: when the load of vines is large and there are too many inflorescences, it is necessary to sparse the inflorescences. Sparse the weak inflorescences with poor development and inflorescences with dense distribution or inappropriate positions, so that nutrients can be supplied to the reserved excellent inflorescences in a centralized way. In addition, the sparse inflorescence can also be thinned from before flowering to flowering on the basis of pruning.
ear thinning: on the basis of thinning the redundant inflorescences, in order to further reduce the unnecessary consumption of nutrients, ear thinning should be carried out after the grapes fall naturally and physiologically, and the redundant ear or fruit grains should be thinned as soon as possible.
Fruit and vegetable grains: The purpose of grain thinning is to make the ear of fruit neat, the size of fruit grains consistent, and increase the weight of fruit grains. From fruit setting to hard core stage, seedless small fruits with poor pollination and fertilization and fruit grains that are too tight in the ear are thinned. According to the size of fruit grains, the suitable distance between grains is determined, with less fruit grains for large-grain varieties and more fruit grains for small-grain varieties.
Third, the key period of pest control
Chemical control: Before germination, spray stone sulfur mixture+"tree protection general" for disinfection and sterilization to effectively control grape black pox and red spider and other pests; Strengthen the prevention and control of pests and diseases in the peak period of July-August, and spray Bordeaux mixture throughout the garden, which has a good effect on grape white rot, downy mildew, anthracnose, leafhopper, leafhopper and so on.
