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 .5kg/hm2 处理最佳 ,增产皮棉 15 %。Effects of mulching with liquid film on the yield o f 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 boll weight. Also a more reasonable time and space distributio n of boll setting, a decreased number of rot bolls, an increased number of high quality bolls and a higher lint yield were observed. Of all the treatments, T2 was the best, and lint output was increased by 15%.
