Code of practice for the production of pollution-free Chinese medicinal materials

Operating rules for the production of pollution-free Chinese Medicinal Materials

I. Environmental conditions requirements

1. The overall requirement of producing area selection is that the producing area of pollution-free traditional Chinese medicine should be good, free from or not directly affected by industrial "three wastes" and agricultural and urban life, and free from endemic diseases. At the same time, the production capacity of the place of origin. The pollution sources in the producing area, upwind and upstream of irrigation water sources are not a threat, including industrial "three wastes", agricultural wastes, materials, urban garbage and domestic sewage. The place of origin should avoid the main highway. The area with high background value of heavy metals in soil and soil and water source should not be used as the producing area of pollution-free traditional Chinese medicine.

two。 Air quality the ambient air quality of the producing area of traditional Chinese medicine shall comply with the provisions of Table 1.

3. Irrigation water quality the irrigation water quality in the producing area of traditional Chinese medicine should comply with the provisions of Table 2.

4. Soil environmental quality the soil environmental quality of the producing area of traditional Chinese medicine should conform to the provisions of Table 3.

II. Product requirements

1. Sense requires that the product should have the characteristics that this kind of traditional Chinese medicine should have when harvested. It requires moderate maturity, good appearance and color, clean, no mildew, no smell, no diseases and insect pests and mechanical damage.

two。 Safety requirements: pollution-free Chinese medicinal materials should meet the safety indicators listed in Table 4.

III. Guidelines for the use of pesticides

1. When using the principle of pesticide to control diseases and insect pests of Chinese medicinal materials, the principle of "prevention first and comprehensive control" should be carried out, on the basis of agricultural control, effective non-chemical control measures such as biological, physical and ecological control should be adopted as far as possible. Efficient and safe chemical agrochemicals should be used when chemical pesticides must be used. Strict enforcement of GB4285 "Agricultural Drug Safety Standard" and GB8321.1-GB8321.5 "Pesticide rational use Standard guidelines 1mur5" shall not exceed the scope of their use, and pesticide residues in Chinese herbal medicines meet the relevant national health standards.

two。 Types of pesticides commonly used (see Table 4)

IV. Principles of fertilization

The fertilization of pollution-free agricultural products should be based on organic fertilizer, supplemented by chemical fertilizer, and the conditional limited use of chemical fertilizer should be allowed. Balanced fertilization must be carried out according to the law of crop fertilizer demand, soil fertilizer supply and fertilizer effect, so as to maximize the balance of farmland soil nutrients and improve soil fertility, and reduce the pollution of agricultural products and the environment caused by excessive loss of fertilizer components.

1. Types of fertilizers allowed to be used

(1) Farm manure. Refers to fertilizer that contains a large number of biological substances, animal and plant residues, excreta and other substances. They should not adversely affect the environment and crops. In the process of preparation, farm fertilizer must be fermented at high temperature to kill all kinds of parasite eggs, pathogens and weed seeds, remove harmful organic acids and harmful gases, and meet the harmless health standards. The main farm fertilizers are: compost, retting fertilizer, ash fertilizer, barnyard manure, biogas fertilizer, green manure, cake fertilizer, mud fertilizer and so on.

(2) commercial fertilizer. It mainly includes refined organic fertilizer, organic-inorganic fertilizer, microbial fertilizer, humic acid fertilizer, inorganic (mineral) fertilizer, single fertilizer, compound fertilizer, compound fertilizer, nitrate fertilizer, trace element fertilizer, foliar fertilizer, medium element fertilizer, magnetized fertilizer, plant growth auxiliary fertilizer and so on.

(3) other fertilizers. Including food without synthetic additives, organic by-products of textile industry, fish dregs without preservatives, cow wool waste, bone meal, amino acid residue, livestock processing waste, sugar mill waste and other organic materials. two。 The use of nitrate nitrogen fertilizer, compound fertilizer and compound fertilizer containing nitrate nitrogen shall not be used; the use of harmful garbage, sludge and sewage such as urban hospitals and industrial areas shall be prohibited, and no chemical fertilizer shall be used 20 days before harvest.
