| 摘 要： | 采用大田试验,设计冬小麦(Triticum aestivum Linn.)在春季起身后套作半夏Pinellia ternata(Thunb.)Breit.](小麦/半夏)、冬油菜(Brassica campestris L.)收获后复播半夏Pinellia ternata(Thunb.)Breit.](油菜-半夏)和春玉米(Zea mays L.)与半夏Pinellia ternata(Thunb.)Breit.]间作(玉米+半夏)3种耕作模式,探讨晋南两熟半干旱区适宜半夏的粮药耕作模式。结果表明:与油菜-半夏、玉米+半夏耕作模式相比,小麦/半夏耕作模式经济产量最高,生态效益最好;不同半夏品种中,西河半夏(原产地温度相对最低)产量最高,新绛半夏(原产地温度相对较高)产量最低。表明半夏适宜于从低温地区引种到高温地区栽培,可提高产量。与商洛半夏和新绛半夏相比,西河半夏分别增产19.1%和41.9%;小麦/半夏耕作模式为最佳粮药耕作模式,其半夏产量与油菜-半夏和玉米+半夏耕作模式相比,分别增产53.4%和70.8%。

| Abstract: | Field experiments were conducted to investigate the suitable cropping patterns of grain crops and medical plant Pinellia ternata in the two ripe and semi-arid region of southern Shanxi.Three cropping patterns were designed,including,wheat-Pinellia ternata intercropping(wheat/ Pinellia ternata),cole followed by sequential planting of Pinellia ternata(cole-Pinellia ternata),and corn-Pinellia ternata intercropping(corn/Pinellia ternata).Of the three patterns,wheat/ Pinellia ternata was the best in economic yie... |
