First of all, there must be good varieties, and then the plant itself must have a good root system and the soil in which it grows must be good. If the soil root system is not good, its own stress resistance will be weak.
Solution: If the plant The root system itself is strong, the growth is good, the soil is nutritious and healthy, and it can generally reduce the resistance to pests and diseases, so that the plants can reduce the occurrence of pests and diseases, and once it occurs, it can be solved with ordinary medicines, so users will not risk using it.
How to solve the problem of soil root nutrition and health? You can fertilize with biological bacteria that contain nutrients multiple times to replenish organic matter to the soil, supplement the nutrients needed by plants, and promote root growth, which is useful for preventing plant rot. It has a good effect on root dead trees, repeated crop diseases, root-knot nematodes and harmful bacteria, and solves the problem fundamentally.
Not paying attention to the use of medium and trace element fertilizers will also lead to poor plant resistance. Therefore, plants need to be regularly supplemented with a certain amount of medium and trace element fertilizers every year and sprayed on the leaves multiple times to achieve calcium and boron at the same time. Supplementary calcium boron foliar fertilizer improves plant resistance.
