[目的]探索麦棉套作模式下适宜的棉花与小麦配置方式,实现麦棉套作产值最大化。[方法]采用大田随机区组试验,设置了6个不同配置方式,调查了小麦产量、棉花生育性状与产量,计算了不同种植模式的总产值。[结果]“三一式”对棉花前期生长影响较大,棉行光照、温度均显著降低,小麦产量高而棉花产量低;“四二式”起垄植棉促进棉花早发,显著提高了棉花产量,总产值达到了41 646元/hm~2,较其他配置方式增加4.7%~14.5%。[结论]“四二式”配合棉行起垄是促进棉花早发,提高麦棉套作模式产值的最佳配置方式。
[Objective] The study aimed to explore the suitable arrangement of cotton and wheat in wheat-cotton intercropping system and maximize the output value of wheat-cotton intercropping system. [Method] With field randomized block experiment, six different configurations were set up. Wheat yield, cotton fertility traits and yield were investigated, and the total output value of different cropping patterns was calculated. [Result] “Sanyi” had a great influence on early cotton growth, the light and temperature of cotton were significantly reduced, the yield of wheat was high and the yield of cotton was low. , Significantly increased cotton production, the total output value reached 41 646 yuan / hm ~ 2, compared with other allocation increased 4.7% to 14.5%. [Conclusion] “Four or two types” combined with the cotton rowing ridge is the best way to promote cotton’s early onset and increase the output value of wheat-cotton intercropping system.
