ABSTRACT
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.
