摘要: 研究了液体地膜对棉花成铃及产量的影响.结果表明:液体地膜覆盖使棉铃干物质积累加快,铃重有所提高;成铃时空分布合理,烂铃减少,优质铃增加,具有明显的增产效果.其中112.5 kg/hm2处理最佳,增产皮棉15%.

关键词: 液体地膜, 抗虫棉, 成铃, 产量

Abstract: Effects of mulching with liquid-film on the yield of cotton were studied in this paper in 2000 and 2001, using pest-resistant cotton variety of ? 99B?.It promoted the accumulation of dry matter in cotton fruits and enhanced the bolLweight.Also a more reasonable time and space distribution of bolLsetting, a decreased number of rot bolls, an increased number of high-quality bolls and a higher lint yield were observed.Of alLthe treatments, T2 was the best, and lint output was increased by 15%.

Key words: Mulching with liquid-film, Pest-resistant cotton variety, Retained boll, Yield
