title: [Determination and analyse of soil fertility of Pseudostellariae Radix planting base of Shibing County and Huangping County in Guizhou Province].
abstract: OBJECTIVE
  To determine soil fertility of the Pseudostellariac Radix planting base of Shibing County and Huangping County in Guizhou Province, and to provide experimental basis for soil improvement and balanced fertilization.
  
  
  METHODS
  12 soil samples from Shibing County and 10 soil samples from Huangping County were involved in the detection.
  
  
  RESULTS
  In the soil samples from Shibing County, the contents of organic matter, total N, available N, total P, available P and available K were higher, while the content of total P was at middle level. In the soil samples from Huangping County, the contents of total N, available P, total K and available K were higher,the contents of organic matter, total K and available N were at middle level.
  
  
  CONCLUSIONS
  The level of soil fertility of the Pseudostellariae Radix planting base in Guizhou Province is common. The soil fertility of Shibing County is superior to that of Huangping County. The soil pH value of Shibing and Huangping County is low. In Shibing County, lime, farmyard manure and neutral fertilizer can be used to increase the pH of soil. Potash fertilizer can be increased, while nitrogen fertilizer and phosphate fertilizer can be reduced in the soil of Shibing County. Potash fertilizer and phosphate fertilizer will be increased, while nitrogen fertilizer can be reduced in the soil of Huangping County. The soil fertility can be improved by these measures.
