不同pH值土壤对野扇花理化指标的影响

野扇花作为野生植物资源尚处于被开发阶段,目前的研究主要在繁殖技术、光合生理和药理化学方面,对于不同酸性土壤中野扇花生长情况的研究还是空白,为了更好的使其作为园林绿化植物被开发利用,本研究拟在分析出野扇花适宜生长的生态条件。本研究主要采取了黑色石灰土,石灰土和黄壤3种贵州常见土壤种植野扇花,跟踪测定理化指标。结果表明:野扇花可以生长的土壤pH值范围比较广,但是适宜生长的范围为中性至弱碱性。

Influence of pH Values in Soil on Physical and Chemical Indexes of Sarcococca ruscifolia Stapf

Sarcococca ruscifolia Stapfhas not yet been fully developed as a wild plant resource. So far the study of Sarcococca ruscifolia Stapf is mainly in the respects of breeding technology, photosynthetic physiology and pharma- cological chemistry. However, there is no study of growth of Sarcococca ruscifolia Stapf in different ph soils. This study uses three soils commonly seen in Guizhou province to determine physical and chemical indexes of Sarcococca rtucifolia Stapf. The results show that Sarcococca ruscifolia Stapf can grows in a wide range of pH values in soil. The favorable conditions range from neutral to week alkali.
