摘要 在大田试验条件下,研究了不同地膜覆盖方式(半膜覆盖、全膜覆盖、无膜覆盖)对棉铃对位叶生理特性及产量的影响。试验结果表明:与其他覆膜方式相比,在半膜覆盖方式下,棉铃对位叶中可溶性糖、氨基酸和可溶性蛋白含量较高,内源性保护酶SOD、POD和CAT活性较强,MDA含量较高,促使单株成铃率高,单株成铃个数多,最终籽棉、皮棉产量较高。说明半膜覆盖方式可以促进棉铃对位叶的生理代谢活动,有利于棉花产量的形成。 Under the condition of field,we studied the effects of different plastic film mulching ways(half plastic film mulching,complete plastic film mulching,no plastic film mulching) on the physiological characteristics of boll-subtending leaf and the yield of cotton. The results of experiments showed that: in comparison with other plastic film mulching ways,the half plastic film mulching way could increase the contents of soluble sugar,amino acids,soluble protein and MDA in boll-subtending leaf,and could enhance the activities of endogenous protective enzymes(SOD,POD and CAT),which led to higher single-plant bollforming rate,more bolls per plant,and higher seed-cotton yield and lint-cotton yield. It is concluded that the half plastic film mulching way can promote the physiological metabolic activity of boll-subtending leaf,and is beneficial to the formation of cotton yield.
