摘要
对不同熟期棉花在不同地膜覆盖方式下的产量进行对比研究.结果表明:地膜覆盖显著提高了棉花的产量、铃数和铃重,但对衣分的影响不大;地膜覆盖对霜前花率都有提高,现蕾期揭膜提高显著;不同熟期品种间各项指标差异均显著.
The yields of cotton in various mature period under different film mulching methods were studied contrastively. The results showed that film mulching increased the number of bolls, the weight of boll and the yields significantly, but little impact on lint percentage. In addition, film mulching could improve the rate of pre-frost lint, and it increased remarkably uncovering film in squaring period. All indicators were significant between different cotton varieties in mature period.
