小麦/玉米间作—复种娃娃菜机械化高效栽培模式OA
Mechanized High-efficiency Cultivation Mode of Wheat Intercropping Maize Followed by Baby Cabbage
为应对甘肃酒泉地区农业面临的连作障碍加剧、种植效益下滑及劳动力短缺等问题,创新构建了"小麦/玉米宽幅间作—复种娃娃菜"周年高效栽培模式.该模式通过等宽比(行宽比为1:1)带状种植与年度带位轮换机制缓解连作障碍,利用麦后光热资源复种娃娃菜提升资源利用效率,并优化全程机械化作业体系.经试验验证,该模式较玉米单作每667 m2增收298.7元,增幅37.3％,较小麦单作增收535.9元,增幅95.0％,经济效益提升显著,为河西走廊绿洲农业区实现"稳粮增收"与农业现代化提供了可行的技术路径.
To address the challenges of increasing continuous cropping obstacles,declining planting efficiency and labor shortages in the agricultural sector of Jiuquan,Gansu,an innovative high-efficiency annual cultivation mode of'Wheat and Maize Wide-Row Intercropping-Replanted Baby Cabbage'was developed.This mode alleviates continuous cropping obstacles through an equal-width ratio(1:1)strip planting system combined with annual strip rotation,enhances resource utilization efficiency by replanting baby cabbage using post-wheat light and heat resources and optimizes a fully mechanized operation system.Experimental verification showed that the mode increased income by 298.7 yuan per 667 m2(a 37.3％increase)compared to maize monoculture and by 535.9 yuan per 667 m2(a 37.3％increase)compared to wheat monoculture,significantly boosting economic benefits.It provides a feasible technological pathway for achieving'stable grain production and increased income'and promoting agricultural modernization in the oasis agricultural areas of the Hexi Corridor.
