山西省褐土土壤养分限制因子研究

Study on the Soil Nutrients Limiting-factors in the Cinnamon Soil of Shanxi

采用土壤养分状况系统研究法,通过化学分析、吸附试验及盆栽试验,以玉米为栽种作物,对左权、和顺褐土土壤的养分限制因子进行系统研究。结果表明:左权土壤养分限制因子主要是P,N,Zn,Cu,和顺项目区土壤养分限制因子主要是P,N,K。

The soil nutrients limiting factors of the Cinnamon of Zuoquan and Heshun were studied with a systematic approach technique on soil nutrient status through laboratory analysis,absorption study and pot experiment.the result displays that the main soil nutrients limiting factors of Zuoquan Cinnamon soil are P,N,Zn,Cu and P,N,K of Heshun.
