不同种植模式对间作棉花生长发育和产量的影响

Effects of Different Planting Pattern on the Development and Yield of Intercropping Cotton

采用小区田间实验,设置3种不同种植模式(1)M1:在距离红枣1.5m处种植两行2行棉花;(2)M2:在距离红枣1.0 m处种植4行棉花;(3)M3:在距离红枣0.5 m处两行种植6行棉花。探索3种不同种植模式对间作棉花生长发育状况和产量的影响。结果表明,在M2种植模式下植株的株高较高,成铃数相对较多,叶片的净光合速率较大,籽棉产量较高。枣棉间作下,不同种植模式对棉花的生长发育和产量有一定的影响,适宜的间作种植模式能有效的改善和优化作物的生长和发育,从而可以增加产量和提高经济效益。

Three jujube and cotton intercropping pattern of two lines of cotton with the distance of 1. 5m to Jujube（ M1）,four lines of cotton with the distance of 1. 0m to Jujube（ M2）,and six lines of cotton with the distance of 0. 5m to Jujube（ M3） were used,a field experiment was conducted to investigate the effects of different kinds of jujube and cotton intercropping pattern on the growth and yield of cotton. The results showed that,the jujube and cotton intercropping pattern effected greatly on the cotton＇s development and yield,and the M2 had the highest plant height,more boll setting,highest net photosynthetic rate,higher seed cotton yield. It indicated that appropriate planting patterns of Jujube and cotton intercropping could efficiently promote the growth and development of cotton,thus the economic benefit also increased accordingly.
