Based on the analysis of Fritillaria thunbergii Miq. production in Yinzhou District in 2015,this paper firstly introduced current situation of Fritillaria thunbergii Miq. planting. The competition of Fritillaria thunbergii Miq. products was in disorder,the market price in 2015 dropped to half in 2014,and many Fritillaria thunbergii Miq. growers suffered losses. To keep sustainable development of traditional Fritillaria thunbergii Miq. industry in old production areas and maintain brand and name of genuine materials of " Zhejiang 8 Famous Kinds Herbal Medicines",it is required to actively reduce the inventory,make up short board,strengthen advantages,implement the reform of supply font,keep up with the times and market,and succeed through improving the quality.展开更多

Much recent work has indicated that the structure and growth of mixed species forests may fundamentally differ from monocultures. Here we suggest how to progress from the present accumulation of phenomenological findings to a design of mixed-species stands and advanced silvicultural prescriptions by means of modelling. First, the knowledge of mixing effects on the structure and growth at the stand, species, and individual tree level is reviewed, with a focus on those findings that are most essential for suitable modelling and silvicultural designs and the regulation of mixed stands as opposed to monocultures. Then, the key role of growth models, stand simulators, and scenario assessments for designing mixed species stands is discussed The next section illustrates that existing forest stand growth models require some fundamental modifications to become suitable for both monocultures and mixed-species stands. We then explore how silvicultural prescriptions derived from scenario runs would need to be both quantified and simplified for transfer to forest management and demonstrated in training plots. Finally, we address the main remaining knowledge gaps that could be remedied through empirical research.展开更多

Methods: Based on the principal component analysis of element contents in Chinese herbs, the effects of 25 chemical elements in the 11 kinds of Chinese herbs in the caine kidney mixture have been analyzed. Results: The traditional Chinese medicines of rehmannia, astragalus, mulberry, salvia miltiorrhiza, rhubarb in the caine kidney mixture play a major role in the treatment of chronic renal failure. Conclusion: The principal component analysis is very practical in the compatibility of medicines and concentrated prescriptions.展开更多
