Six "not paying attention" will hurt the fruit tree

Pay attention to treatment and not protect many fruit farmers. In the control of fruit tree diseases and insect pests, if no fruit tree diseases and insect pests are seen, no medicine will be used. After the onset of the disease, a large number of systemic therapeutic agents are applied, resulting in rapid drug resistance; the disease quickly rebounds, leading to long-term cure; high cost of prevention and control, and threatening food safety.

Random use of drugs, careless use of cross-mixing and application of pesticides, not only has a bad effect, but also wastes pesticides, easily causes residual residue problems, increases environmental pressure and environmental pollution.

Pesticides should be cross-used to delay the resistance of the disease. If the same medicine is used every time, it will not work if it is applied several times.

Paying attention to fruit and not paying attention to the leaves After fruit hanging, some fruit farmers only pay attention to the ears and leaves, which is wrong. The growth and development of the fruit are all based on the nutrition produced by the leaves. If the leaves are not good, the fruits cannot grow and mature normally, nor can they produce high-quality fruits. Therefore, we must attach importance not only to the control of diseases and pests on fruits, but also to the control of diseases and pests on leaves.

Paying attention to pre-harvest, not post-harvest post-harvest is as important as pre-harvest, because the nutrients produced by the leaves after harvest are used for flower bud differentiation, mature shoots, root growth, and root nutrient accumulation. This is the basis for the growth and harvest of fruit trees in the second year. Once the leaves are not protected after harvesting, it will cause a series of problems in the second year: yellow leaves after germination, poor growth, small inflorescences or poor inflorescence shapes, and flower development. Bad results caused a lot of flowers and fruits.

Pay attention to the aerial part, but not to the fruit of the underground part. The fruits of the tree should be supported by the nutrients produced by the leaves, and the leaves should be supported by the nutrients and water absorbed by the roots. In a sense, the amount of yield depends on the number of leaves, and in a sense, the number of leaves depends on the number of roots and the degree of robustness. How the root system looks depends on soil and root management. Therefore, we must pay attention to soil issues, including permeability, organic matter content, water, and fertilizer, and we must also pay attention to field root management.

Pay attention to medicaments, do not pay attention to medicaments of good quality, and spray them in place to have good results. For protective fungicides and contact insecticides, spray the drug evenly. Where the drug is not sprayed, the germs or insects will not be killed if they do not touch the drug. For osmotic drugs, there will be no spray. Although there is medicine entering the leaves, but no medicine is transmitted through it, it will not kill the germs.
