Planting grape trees can adopt scientific management to prevent diseases and pests. Scientific management includes reasonable close planting, scientific fertilization, clearing orchards and so on. Reasonable close planting refers to maintaining a reasonable distance during planting, sharing nutrients and light to the greatest extent, and controlling the propagation speed of pests at the same time. Scientific fertilization refers to timely topdressing to provide nutrition for plants and improve their ability to resist diseases and pests. Clearing the orchard can directly kill the pests hidden in the soil for the winter and reduce the incidence of pests in the coming year. 1、 How to prevent insects in tree grapes? When planting tree grapes, keep reasonable plant spacing and spacing. They grow better in a ventilated and transparent environment and have high disease resistance. Due to the great demand for fertilizer during the growth of grapevine, it is necessary to strengthen fertilizer management and improve their resistance. Apply more potassium, phosphorus and calcium fertilizers to help them grow and prevent diseases and pests.
After the branches and leaves wither in autumn, the orchard can be greatly changed, the land can be deeply turned over, and the deciduous weeds can be concentrated, which can wipe out the living environment of diseases and pests and prevent the occurrence of diseases and pests in the coming year. 2、 How to fertilize grapevine 1. Grapevine has a large demand for fertilizer during the growth period. Pay attention to the application of organic fertilizer after planting. It can be mixed with organic fertilizer, microbial fertilizer and chemical fertilizer. Their demand ratio for nitrogen, phosphorus and potassium is 1:2:1.
2. Fertilize according to their growth stage and growth status. For example, nitrogen fertilizer, phosphorus, potassium fertilizer and urea are applied at flowering stage, coloring stage and fruiting stage respectively.
3. When applying fertilizer, it is best to ditch and apply fertilizer to let the roots of plants absorb naturally, which can reduce the burn of roots to the greatest extent. An annular ditch can be dug around the root system to supplement fertilizer in an all-round way. （ShuPuTaoZenMeFangChong）
