[Assessment of soil fertility for cultivation of Chinese herbal medicines].

The soil fertility has great impacts on the yielding of Chinese medicinal materials, as well as the generation of major components. The practices showed that soil fertility has been decayed with the growth of cultivation years,which is leading to adverse effect on quality and quantity of Chinese medicinal materials. However, there was a lack of domestic unified standard for assessment of soil fertility of Chinese medicinal material cultivation, which has seriously limited the soil management and quality control. In this text, we reviewed the progress on research of soil fertility evaluation, built the soil fertility evaluation index including soil texture,soil bulk density,soil organic matter,soil acidity and alkalinity,soil available nitrogen,soil available phosphorus, soil available potassium,soil animals and soil microorganisms. It would provide the direction and thought for standard-settin on soil fertility evaluation of Chinese medicinal material cultivation.
