However, the long-term dependence and extensive use of organic synthetic chemical pesticides have brought about a series of problems such as environmental pollution, ecological balance damage and food safety, which have brought many adverse effects on promoting the sustainable development of the agricultural economy.

Chemical fertilizers can increase the yield of crops, but long-term application of chemical fertilizers will cause many disadvantages, including soil compaction, product quality decline, etc.

Residents in both urban and rural areas have this feeling: vegetables are becoming less and less fragrant, and the aroma of rice is becoming weaker and weaker. Excessive use of chemical fertilizers is one of the main reasons.
