辽西北地区麦棉菜套复种高效栽培研究

[目的]提高小麦（粮食）产量，利用棉花及麦茬作物提高经济效益。[方法]试验设麦棉套种麦茬复种白菜、小麦清种麦茬复种白菜、棉花清种3个处理，研究各作物的生育进程及表现。[结果]最佳麦棉套种模式：设2．6m一带，麦畦宽1．6m，种10行；棉垄1．0m，种双行；麦茬根据市场需求复种适宜夏种秋收的蔬菜。[结论]这种栽培模式既增加了麦、棉的纯面积产量，又提高了单位土地面积的经济效益，是一种较好的高产高效栽培模式。

Three Planting and Three-harvesting High-effect Pattern Studies on Intercropping Cotton with Wheat and Replanting Autumn Vegetable after Wheat in the Northwest of Liaoning Province

[Objective]The research aimed to improve the yield of wheat(grain),improve the economic benefits using cotton and crops after wheat.[Method]Three treatments of intercropping cotton with wheat and multiple cropping cabbage,wheat monocropping and multiple cropping cabbage,cotton monocropping were setted to study the development process and performance of each crop.[Result]The best intercropping of wheat and cotton pattern was as following: planting cotton by big ridge double lines with 1.0 ridge per meter,planting wheat by wheat bed of 1.6 meter wide,and then replanting suitable vegetables according to market demand,which was 2.6 meter per belt.[Conclusion]It was a kind of high yield and high benefit pattern,which increased the yield per unit pure area of wheat,cotton,and enhance economic efficiency per unit area.
