RESUMEN
As a commonly used traditional Chinese medicine,Stellaria dichotoma var. lanceolata has a medicinal history of several hundred years, and been included in the Pharmacopoeia of the People's Republic of China. With a sweet fact and mild war nature, it enters liver and stomach meridians. With effects in clearing deficient heat and eliminating fever in infantile malnu, it has been used to treat such diseases as Yin deficiency fever, consumptive fever due to Yin deficiency and infantile chancre fever, and taken as the raw materials of Wuji Baifeng Wan and other traditional Chinese medicine preparations. In recent years,there have been increasing demands for S. dichotoma var. lanceolata from people. However, its wild resources have been over-excavated for a long time,leading to a serious shortage of wild strains. Furthermore, the quality of artificial S. dichotoma var. lanceolata medicine is far different from that of wild cultivars. Meanwhile,pesticide residues and excessive metal standards due to the irrational use of pesticides and chemical fertilizers in the production process, as well as the large number of counterfeits in the market seriously impact the quality,efficacy and drug safety of S. dichotoma var. lanceolata medicine. Therefore, the non-polluted production technology of S. dichotoma var. lanceolata is of great significance. The non-polluted production technology would be an effective mode for promoting the sound development of S. dichotoma var. lanceolata industry in the future and the key to solve the issues. This article summarizes the environment of suitable production area,plantation method, comprehensive soil improvement, field management and rational fertilization technology. It also proposes that the prevention and control of pollution-free safflower pests and diseases should follow the principle of giving priority to comprehensive prevention. The pollution-free and technical regulation system of S.dichotoma var. lanceolata cultivars is built to produce excellent,high-quality and non-polluted production with low content of pesticide residues and heavy metals,and promote the healthy and sustainable development of the global S.dichotoma var. lanceolata industry.
RESUMEN
The problems of non-standard use of pesticides, and excessive pesticide residues and excessive heavy metal, etc. are common in the productive process of safflower (Carthamus tinctorius) and they are the factors restricting the sustainable development of safflower industry. Pollution-free production is an effective measure to ensure high quality of safflower. This paper summarized the environment of production area, selection of improved varieties for the production in the local places and its characteristics, the standardized comprehensive agronomic management and pollution-free rational fertilization technology. Additionally, the pollution-free control of safflower pests and diseases should follow the principle of priority to prevention and comprehensive prevention. Agricultural, biological and physical control should be preferred to use, and be combined with safe and low toxicity of chemical control. The standardization and industrialization of safflower production were realized by the construction of a comprehensive control technology system of pests and diseases of pollution-free safflower, which promoted the healthy development of the safflower plantation industry and achieved pollution-free standards.
RESUMEN
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.
