Agrochemicals refer to inputs such as chemical fertilizers, pesticides, veterinary drugs and growth regulators in agricultural production, which can promote the production of edible agricultural products and play an important role in the sustainable and rapid development of agriculture. It can be divided into three categories: chemical fertilizer, pesticide and agricultural film. Chemical fertilizer, also known as chemical fertilizer, refers to fertilizers made by chemical and physical methods that contain nutrients needed for the growth of one or more crops. They are mainly used to improve soil fertility and increase crop yields. Common fertilizers are nitrogen and phosphorus fertilizers. Pesticide refers to the protection of the healthy growth of crops, the use of germicidal and insecticidal products. Agricultural film is mainly used for mulching cultivation, which plays an important role in the production of off-season products.
These three kinds of agrochemicals will cause certain pollution to the environment. The extensive use of chemical fertilizer pollutes the soil and changes the acidity and alkalinity of the soil, and the chemical fertilizer flows into the groundwater through the surface runoff, which pollutes the lakes, rivers and so on. Although pesticides play an active role in the process of crop production, pesticide residues are also harmful to people's health. The molecular composition of agricultural film is very stable and difficult to degrade, which leads to too much plastic residue and serious environmental pollution.
So we should use chemicals scientifically:
1. Increase the dissemination of scientific knowledge on the use of agrochemicals
2. Strengthening the Prediction of Diseases and insect pests
3. Research on New Agricultural Chemicals
4. Introduce and popularize new technologies
5. Perfecting the legal system and strengthening Market Monitoring
