摘要
通过对不同麦棉套作模式对棉花影响的研究表明 ,不同种植模式对棉花与小麦共生期间生理生态等因子的影响不同 ,导致棉花产量结构因子的差异 ,最终导致棉花产量的不同。套作棉花产量与单作棉比较 ,均表现出减产 ,减产幅度介于 2 .0 6 %～ 7.0 6 %。究其因在于单位耕地面积成铃数少。四种套作模式相比 ,以 3∶ 1式产量最高 ,产量达 72 .4 3kg/ 6 6 6 .7m2 ,其成铃数。
The effects of various planting patterns in relay intercropping of wheat and cotton were studied.The results were stated that ecological and physiological factors were different during wheat and cotton intergrowth.The cotton yield varied with different planting patterns. The yield of relay intercopping cotton was less than that of single cropping.The range of decreasing yield was 2.06%～7.06%.The yield of 3∶1 pattern was greatest of four relay intercroppings.Its yield was 72.43kg/666.7m 2.
