摘要
研究了在甘肃兴电灌区灌耕灰钙土玉米、蚕豆单作和间作模式对产量和经济性状的影响。结果表明,玉米蚕豆全覆膜带田优化施肥种植模式(玉米带80 cm种2行,蚕豆40 cm种2行,施肥量为N 300 kg/hm2、P2O590 kg/hm)2玉米产量比单种玉米增产9.41%;蚕豆产量虽比单种蚕豆减产23.89%,但比玉米蚕豆带田传统种植模式增产27.03%,且蚕豆分枝数、株粒重、百粒重和玉米穗长、穗粒重、百粒重均表现最高,可作为兴电灌区玉米蚕豆带田的最佳种植模式进行推广。
Effects on crop yield and economic characters of mono-cropping or inter-cropping maize and broad bean in irrigated sierozem of Gansu Xingdian irrigation areas were studied. The results showed that the yield of corn/broad bean with full film and optimized fertilization increased by 9.41% than mono-cropping corn, and decreased by 23.89% than mono-cropping broad bean, but enhanced by 27.03% than the traditional planting pattern; Branch number, grain weight per plant, hundred grain weight of broad bean and ear length, grain weight per ear, hundred grain weight of corn were the highest of all treatments; pod number per plant, grain number per pod, grain number per plant of broad bean and ear diameter, grain number per ear of corn, but slightly lower than that of mono-cropping broad bean and mono-cropping corn, were the highest in the intercropping patterns, so corn/broad bean with full film and optimized fertilization was the best planting pattern of corn and broad bean in Xingdian irrigation areas.
