杜仲林不同混农林经营模式对土壤的影响及效益评价

Effects of Different Agroforestry Management Model on the Soil of Eucommia ulmoides and Evaluation

通过对黔中地区杜仲林三种混农林业经营模式的研究 ,结果表明 :在改善土壤结构和水分物理性质 ,土壤有机质、全氮、全磷、全钾含量多少等方面的排序是 :杜仲 +白术模式 >杜仲 +紫苏模式 >杜仲 +辣椒模式 ;各经营模式经济产出多少的排序是 :杜仲 +白术模式 >杜仲 +辣椒模式 >杜仲 +紫苏模式 ;从土壤有效磷含量看是杜仲 +辣椒模式 >杜仲 +紫苏模式 >杜仲 +白术模式。杜仲

Researched the three kinds of agroforestry management model in Eucommia ulmoides forest in the middle of Guizhou, and the results are listed as follows: the order is Eucommia ulmoides + Atractylodes macrocephala koidz's model> Eucommia ulmoides + Perilla frutescens (L.) Britt's model> Eucommia ulmoides + hot pepper' s model in improving soil structure, water physical nature, soil organic substance,and the content of total N?total P?total K.In economic output, the order is: Eucommia ulmoides + Atractylodes macrocephala koidz's model> Eucommia ulmoides + hot pepper' s model> Eucommia ulmoides + perilla frutescens (L.)Britt's model;But the order is Eucommia ulmoides + hot pepperls model> Eucommia ulmoides + perilla frutescens (L.)Britt's model> Eucommia ulmoides + Atractylodes macrocephala koidz's model in the content of available phosphate in soil. In those, Eucommia ulmoides + Atractylodes macrocephala koidz's model is a sustainable management model in the middle of Guizhou.
