1, pay attention to treatment, do not pay attention to protection
Many fruit farmers do not use medicines when they do not see fruit trees and pests in the prevention and control of fruit trees, and they use drugs when they see pests and diseases. After the onset, multiple doses 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, threatening food safety. Do a good job of prevention, and the disease will be reduced a lot in the later stages.
2, use drugs indiscriminately, do not pay attention to cross use
The misconception is that it is more reassuring to use more pesticides and mix them together; if there is no prevention and protection work, after the disease is discovered, the medicines will be used indiscriminately, and various liquid medicines will be mixedly applied.
The application of pesticides in a random mix is ​​not only ineffective, but also wastes pesticides, easily causes problems of excessive residue, increases environmental pressure and environmental pollution.
Pesticides should be cross-used to delay the resistance of the disease. If you use the same medicine every time, it will not work if you use it several times. Nowadays, many diseases are difficult to treat. They are not very ill, but they are resistant to these drugs.
3, attach importance to fruit, do not pay attention to leaves
After the fruit is hung, some fruit farmers only pay attention to the ear and do not pay attention to the leaves. This is wrong. The growth and development of the fruit depends on the nutrients produced by the leaves. The leaves are not good, the fruit can not grow normally and mature, and it can not produce high quality fruit. Therefore, we must pay attention not only to the prevention and control of pests and diseases on the fruit, but also to the prevention and control of pests and diseases on the leaves.
4, pay attention to harvesting, do not pay attention to after harvesting
There is good control of fruit farmers before harvesting, and there is no need for medicine after harvesting. After harvesting, it is as important as before harvesting, because the nutrients produced by the leaves after harvesting are used for flower bud differentiation, old 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, it will lead to a series of problems in the second year: yellow leaves after germination, poor growth, small inflorescences or poor inflorescence shape, flower development. Poorly caused a lot of falling flowers and fruit.
5, pay attention to the above-ground part, do not pay attention to the underground part
The fruit of the fruit tree depends on the nutrients produced by the leaves, and the leaves are supported by the nutrients and water absorbed by the roots.
In a sense, the level of production depends on the number of blades, and the number of blades depends, in a sense, on the number and robustness of the roots. How the roots grow depends on soil and root management. Therefore, we must pay attention to soil problems, including permeability, organic matter content, water, fertilizer, and must pay attention to field root management.
6, pay attention to pharmaceuticals, do not pay attention to the quality of medication
Good pharmacy, sprayed in place to have a good effect. For protective fungicides and contact insecticides, the spray should be uniform, and the place where the medicine is not sprayed, the bacteria or insects will not be killed if they are not exposed to the medicine; for the osmotic agent, there is no place for spraying the medicine. Although some medicines enter the leaves, no medicine is transmitted, and the bacteria are killed.
