    Abstract:
    Aimed to solve the issues of pesticide residue, heavy metal contents and harmful elements in the productive process of Chinese herbal medicines, the research team built the technical regulations for production of pollution-free Chinese herbal medicines. This regulation included the environment of production area, the process of production, quality of products etc., which were the key steps controlled the quality of Chinese herbal medicines. The environment of production area was selected according to the ecological factors which were stipulated by Ecological Suitability Regionalization of Chinese herbal medicines (second edition). The quality of air should be attain the one or two levels of GB/T3095-2012 standard values. The cultivation soils should reach to the one or two levels of GB15618 and NY/T391 standard values. The quality of irrigation water should accord with the stipulation of GB5084-2005. Aimed to the production of Chinese herbal medicines, disease-resistant and superior varieties which were suitable to the local stations should be selected, and the breeding of superior seeds and seedlings should be strengthened. Additionally, rational fertilizer application of pollution-free Chinese herbal medicines should be conformed to the principles, requirements, and the kinds of fertilizers allowed or limited for use, which were stipulated by the standard of DB13/T454. Furthermore, the plant protection policy of priority to prevention and synthetical prevention should be followed; improving ecological environment and strengthening cultivation management should be served as the basics. Agricultural measures, and biological and physical control strategies should be preferred to use; and high toxicity, residue pesticide and its mixture should be inhibited; the use of chemical pesticides should be minimized and then to decrease contamination and residue. Additionally, the quality of products should be reached to the standard of pollution-free Chinese herbal medicines; high toxicity and detection rate of pesticide residues and the contents of heavy metal and harmful elements (e.g. plumbum, cadmium, mercury, arsenic and cuprum) should accord with the common criteria of pollution-free Chinese herbal medicines. Application of technical regulations for production of pollution-free Chinese herbal medicines guarantees significantly social, economic and ecological benefits.
