摘  要：
为了解贵州地产玄参种植土壤养分的丰缺现状,以玄参产地土壤为对象,分析了土壤p H值、有机质和氮磷钾含量,并评价了土壤养分的丰缺现状,讨论了土壤各养分间的关系。结果表明:玄参产地土壤属于弱酸性土壤,土壤有机质含量处于24.86~120.12g/kg之间,土壤有机质含量较高;玄参产地土壤全氮含量处于1.64~1.88g/kg之间,全磷处于0.11~0.21g/kg之间,全钾处于14.34~16.73g/kg之间;玄参产地土壤碱解氮含量处于123.73~269.37mg/kg之间,有效磷处于7.17~21.37mg/kg之间,速效钾处于90.56~251.38mg/kg之间;玄参产地土壤有机质、全氮和碱解氮含量比较丰富,全钾、有效磷和速效钾含量适宜,全磷含量属于缺乏水平。玄参产地土壤各养分中p H值与有机质、土壤有机质与土壤全磷、土壤全磷与土壤全钾成极显著正相关。贵州玄参产地土壤肥力水平总体较高,能够提供玄参生长过程中所需要的养分。

摘  要：
To realize the current situation of soil nutrients and evaluation of abundance of soil nutrients of Scrophulariaceae production areas of Guizhou,the soil samples of Scrophulariaceae producction areas was taken as test materials,the soil p H,organic matter and content of NPK were analyzed and the relationship among soil nutrient was discussed. The results showed that the soil of Scrophulariaceae production areas was weak in acid,abundance of soil organic matter,soil total N and soil available N,the content of soil total k,soil available P and soil rapidly available K were at a suitable level,but the soil total P was insufficient. The test data were as follow: the soil organic matter,soil total N content,soil total P content,soil total k content was between 24. 86 ~ 120. 12 g / kg,1.64 ~ 1. 88 g / kg,0. 11 ~ 0. 21 g / kg,14. 34 ~ 16. 73 g / kg,respectively; The soil available N content was between 123. 73 ~ 269. 37 mg /kg,soil available P content was between7. 17 ~ 21. 37 mg / kg and soil rapidly available K content was between 90. 56 ~ 251. 38 mg / kg.There were a very significant positive correlation between soil p H and soil organic matter,soil organic matter and soil total P,soil total P and soil total k. It can be concluded that the soil fertility was higher to provide nutrients for Scrophulariaceae.
