How much do you know about pesticide spraying saving technology?

For the use of strong water-soluble drugs in rice fields, the pelleting technology can be used, which only needs to be evenly dispersed in farmland, and the efficiency can reach more than 10 times, without pesticide drift and pollution to adjacent crops. Through the method of mixed application, a variety of pests and diseases were controlled by one-time application. However, the mixed pesticides should have good physical properties without increasing the toxicity to people and animals on the premise of retaining the original effective components or having synergistic effect.

In agricultural production, chemicals such as pesticides and fertilizers are the key factors leading to soil acidification, salinization and microbial imbalance, and the application of pesticides and fertilizers is a high-input and high-output operation. If the fertilizer technology is used unreasonably, the effective utilization rate of fertilizer is low, which will not only cause fertilizer waste, but also greatly affect the growth and development of crops. In order to solve this problem, many large and medium-sized rice production enterprises in China use a large number of chemical synthetic fertilizers in the production process. However, due to the high cost of this fertilizer, it is not only used in a large amount but also not environmentally friendly, which seriously affects the normal production of rice.

What should be done to control and control farmland environmental pollution? Reduce reuse? On the premise of ensuring the stability of agricultural production, clean up and control organic pollutants in farmland; On the basis of improving the utilization rate of organic fertilizer, the nutrient distribution mode of organic fertilizer is changed to realize efficient and environmentally friendly application. For example, the organic decomposition and release of organic fertilizer nutrients can reduce the use of pesticides and avoid secondary pollution of pesticides. The cleaning and control of farmland pollutants is also the focus of farmland pollution control at present, which can be carried out by chemical, physical or biological methods.

For example, biochemical methods can be used to improve the utilization rate of pesticides. At the same time, the discharge of pollutants from farmland can be greatly reduced by physical methods. From the above analysis, it can be seen that pesticide control and farmland environmental pollution control are complementary, and both aspects should be strengthened.
