黄土高原半干旱区柴胡种植模式

Cropping patterns of Bupleurum chinense in semi-arid region of Loess Plateau.

采用大田试验,设计冬小麦收获后复播大豆、大豆套作柴胡(小麦-大豆/柴胡)和冬小麦收获后复播柴胡(小麦-柴胡)及玉米套作柴胡(玉米/柴胡)3种种植模式,探讨黄土高原半干旱区适宜柴胡的"粮药"栽培模式.结果表明:与玉米/柴胡和小麦-柴胡种植模式相比,小麦-大豆/柴胡种植模式经济产量最高,生态效益最好;不同柴胡品种中,万柴胡(原产地温度相对较高)产量最高,左柴胡(原产地温度相对较低)最低,表明柴胡适宜从高温地区引种到低温地区栽培,可提高产量.小麦-大豆/柴胡种植模式为最佳"粮药"栽培模式,其柴胡产量比玉米/柴胡和小麦-柴胡种植模式分别增产11.6%和16.8%.

Field experiments were conducted to investigate the suitable cropping patterns of grain crops and medical plant Bupleurum chinense in the semi-arid region of the Loess Plateau.Three cropping patterns were designed,including corn-Bupleurum chinense intercropping（corn/Bupleurum chinense）,wheat followed by soybean-Bupleurum chinense intercropping（wheat-soybean/Bupleurum chinense）,and sequential planting of Bupleurum chinense（wheat-Bupleurum chinense）.Of the three patterns,wheat-soybean/Bupleurum chinense was the best in economic yields and ecological benefits.Among the cultivars（cv.Lingchuan,Zuoquan and Wanrong） of Bupleurum chinense tested,the cv.Wanrong originated from relatively high temperature region exhibited the highest yield,while the cv.Zuoquan originated from relatively low temperature region had the lowest one,indicating that introducing Bupleurum chinense cultivars from the areas with higher temperature to lower temperature areas could increase their yield.The cropping pattern of wheat-soybean/Bupleurum chinense was the most effective one,with the yield being 11.6% and 16.8% higher than that of corn/Bupleurum chinense and wheat-Bupleurum chinense,respectively.
