柴胡不同复种模式的比较研究

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...

A comparative study on different multiple cropping patterns of Bupleurum chinense

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.
