柴胡是山西省的道地药材,种植柴胡是当地农民增收的主要来源之一.在柴胡种植中,小麦-柴胡、玉米-柴胡和大豆-柴胡复种是常用的复种模式.本文研究了3种不同复种方式对土壤氮磷钾含量、柴胡光合参数、柴胡地上部和地下部农艺性状、柴胡皂甙A、C、D含量、柴胡产量和经济效益的影响.结果表明,在大豆-柴胡复种模式下,有利于土壤中氮素的富集,从而促进了柴胡的光合参数、生长发育、柴胡皂苷含量、产量和经济效益.采用大豆-柴胡复种是栽培柴胡适宜的复种模式.“,”Bupleurum chinense is a genuine medicinal material in Shanxi Province,and planting B.chinense is one of the main sources for local farmers to increase their income.In B.chinense cultivation,wheat-B.chinense,maize-B.chinense and soybean-B.chinense are commonly used as multiple cropping patterns.In the present study,we studied the effects of three different multiple cropping patterns on N,P and K levels of soil,photosynthetic parameters,agronomic characteristics,saikosaponin A,C and D contents,yield and economic benefits of B.chinense.The results showed that the soybean-B.chinense multiple cropping pattern was beneficial to the enrichment of N in the soil,thus promoting photosynthetic parameters,growth,saikosaponin accumulation,yield and economic benefits of B.chinense.It is suggested that soybean-B.chinense multiple cropping was an appropriate multiple cropping pattern for local cultivation of B.chinense.
