[0003] At present, the chemical fertilizers used in agricultural prevention and control of pests and crops are mainly mixed with chemical agents and toxic pesticides, and then applied to the soil or crops. Year after year, a large amount of pesticides and chemical fertilizers are used for a long time, causing the pests to develop drug resistance. Soil compaction pollutes water source soil and crops, the quality of agricultural products declines, and pesticide residues exceed the standard, seriously affecting people's physical and mental health and the competitiveness of my country's agricultural products in the international market
