The Study On Good Agricultural Practice (GAP) Of Shezu Medicine Chimonanthus Salicifolius S.Y.H

Chimonanthus salicifolius S.Y.H is Calycanthaceae Chimonanthus, not evergreen frutex, and is commonly called Shiliang tea or Shanla tea in Lishui. It is one kinds of most-widely used Chinese traditional medicine in the civilian She minority. Lishui Chinese medicine hospital did some research in the medicinal effect of chimonanthus salicifolius S.Y.H, and manufactured a new medicine named Pi Weishu by using the distilled oil from stem and leaves. Clinically, this kind of medicine is used to cure dyspepsia, liver-against-stomach, and enteric ills which caused by digestant foul-up such as gastrointestinal discomfort, abdominal pain, windy and lax etc.In September, 2003, National Food and Medicine Superintend Administration Bureau constituted "Chinese traditional medicine products quality supervised criterion (try out)" (Chinese traditional medicine Good Agricultural Practice GAP for short). The practicing of GAP, namely the effective control of the quality of the whole producing process of Chinese traditional medicine, is the guarantee of its steady and controllable quality, also an important measure of clinically safe taking of herbal medicine. It is propitious to Chinese traditional medicine resource's protecting and continual using. What is more, it has significant meaning in promoting Chinese traditional medicine procreative scale, standardization, industrialization and infiltrating the international market.In this paper, we have a study of the chimonanthus salicifolius S.Y.H Good Agricultural Practice (GAP), and the main results are as follow:(1)By establishing the experimental base for systematic study, we mainly work over the relationship between producing process and medicine quality of chimonanthus salicifolius S.Y.H, and therefore regulate the whole processes of its planting and producing, and primarily institute the Standard Operational Practice(SOP) of the chimonanthus salicifolius S.Y.H. We built a 10 hm~2 standard planting basic.(2)We have the environmental detection of plantation in Dendta village of Dadongba, Songyang county, and the results show, the air, soil and water quality all reach national standard, such as GB30951996 (airy environment quality standard), GB156181995 (edaphic environment standard), GB50841992 (farmland irrigative water quality standard). Therefore, this plantation is fit for planting green medicinal materials.(3)We determine that the best seasons of distilling the naphtha of chimonanthus salicifolius S. Y. H is from June to November and Middle April is the best time to make Shiliang tea. We also investigate the skill of making this kind of tea.(4)We investigate the breeding technique of chimonanthus salicifolius S.Y.H. Through the experiments in different period, different foundation and different hormone handling, and using Spring and Fall period to plant and breed, taking 100% perlite as foundation and using the hormone IAA 2000mg/L to soak in the root of spike before planting, the rooting rate reaches up to 70 percent.(5)On the basis of the standard plant of chimonanthus salicifolius S.Y.H. we try the plant of arbor fruit tree—southern precocious pear and special mountainous area little fruit—jingzao persimmon among the young grove of chimonanthus salicifolius S.Y.H. It is a creative mode of Chinese traditional medicine planting. In the prerequisite of ensuring the good quality, stability and recurring of the medicine products, environmental and economic benefits per unit area are raised rapidly, via the effect from each other among different crops.
