At present, the excessive amount of excessive pesticide residues and harmful chemical components in China's fruit production are the main reasons for restricting fruit exports. According to statistics, pesticides account for 70% of organophosphorus pesticides, and organophosphate pesticides account for about 70% of high-toxic pesticides. In 1998, the amount of export agricultural products that failed to pass the inspection of pesticide residues was US$7.4 billion. In order to accelerate the industrialization of the fruit industry and expand the export of fruit, the state has actively taken measures to prohibit the production and use of certain pesticides and chemical fertilizers, and gradually established a system of fruit quality monitoring and inspection standards that are in line with the international market. The China Green Food Development Center has issued the “Green Foodâ€. "Standards", each fruit production area for different tree species, varieties, especially the famous one after another to develop a pollution-free fruit or green fruit production standards or standardized production of local regulations, the majority of farmers must seriously implement, and effectively increase production and income. This article outlines the main content of national pollution-free fruit production. 1. Orchard Address Selection and Fertilizer Irrigation 1. The address of the orchard should be selected in the land where there is no air pollution or water pollution. Should be more than 100 meters away from the railways, highways and docks. Prevent heavy metal (lead, mercury, etc.), sulfur dioxide, arsenic, fluoride, cyanide and other pollution. 2, fertilization: 1 as far as possible the use of farmyard fertilizers (cropped soil, decomposed poultry manure, biogas fertilizer, crop straw fertilizer, mud pond fertilizer, cake fat). 2Use approved chemical fertilizers, commodity organic fertilizers, humic acid fertilizers, microbial fertilizers, organic compound fertilizers, inorganic compound fertilizers, inorganic fertilizers, and foliar fertilizers. 3 Disable fertilizers: A. Urban garbage that has not been harmlessly treated or hazardous waste containing metal or rubber; B. Nitrate nitrogen fertilizer; C. Unfamed human waste; D. Fertilizer products that have not been registered and approved. 3, irrigation water must pass the relevant departments to determine the water quality of qualified (non-polluting) water, can not use sewage, untreated factory wastewater. Second, the rational use of pesticides, caution with plant growth regulators 1, prohibited the use of national banned pesticides and unlicensed pesticides: phorate, phorate, monocrotophos, parathion, methamidophos, omethoate , Insecticide, dicofol, DDT, HCH, Fluoroacetamide, Formamide, etc. 2. Restricted use of pesticides: Lost, anti-inhibition, kung fu, eradication, DDV, deltamethrin, etc. 3. Permitted pesticides: avermectin, imidacloprid, diflubenzuron, nisolulene, diazepam net, cadaverine, bactericide, chlorhexidine, agricultural antibiotic 120, spray gram, Dasheng M-45, Thiophanate, carbendazim, acetaminophen, copper sulphate, lime sulphur, polyoxorubicin, chlorothalonil and others. 4. The last application period of available pesticides must be more than 20 days from the harvesting period, and the restricted pesticides should be more than 30 days. 5. Use plant growth regulators with caution. Benzyl adenine, gibberellins, ethephon, chlormequat and the like can be used.
