The use of fertilizers is mainly based on organic fertilizers and supplemented by chemical fertilizers. The amount of chemical fertilizers is reduced. Chemical fertilizers such as ammonium bicarbonate, diammonium phosphate, potassium dihydrogen phosphate, superphosphate, and ternary compound fertilizer are used in limited quantities. Vigorously promote root-feeding and plant green manure (if planting grass between parks), use decomposed chemical fertilizer-free cake fertilizer, compost, manure, manure, crop straw, humic acid and other organic fertilizers, as well as various microbial fertilizers such as nitrogen fertilizer, Biological potassium fertilizer, photosynthetic micro-fertilizer, soil phosphorus activator, etc. Every time combined with fertilization and sufficient water, the irrigation water must be well water and river water that are not polluted. It is forbidden to use factory waste and organic fertilizer accumulated from municipal waste.

Production of pesticides and fertilizers for use in pollution-free fruits
Pesticides advocate the use of plant-derived pesticides such as nicotine, allicin, rotenone, and parasitic predatory insect natural enemies, insect pheromones, ecdysone and juvenile hormones, and microbial pesticides such as bt biocide, avermectin , antibacterial agents, etc. Choose new pesticides with high efficiency and high biological activity to minimize the amount of pesticides. As far as possible, the dosage form with small environmental impact is used to reduce the pesticide residue. Generally speaking, the granule has little impact on the environment, and the emulsion has a great influence on the environment. For mineral-derived pesticides, copper preparations such as stone sulphur mixture, Bordeaux mixture, copper sulphate and sulfur preparations should be used. Under normal circumstances, organic synthetic chemical pesticides (such as organic phosphorus, organic chlorine, etc.) cannot be used. Chemical pesticides can be used to a limited extent when necessary, but they must be used in strict accordance with the operating procedures and methods of use. Microbial preparations cultivated and produced using various genetic engineering techniques are strictly controlled.
