摘　　要：对两个品种多播期 ,覆膜与不覆膜对比试验结果表明 ,积温与棉花单株产量、棉铃粗纤维含量、棉仁粗蛋白含量呈显著正相关 ;棉铃粗纤维含量与棉花单株产量呈显著正相关。选择适宜品种、适期早播、覆膜 ,能获得较高的积温 ,利于棉铃粗纤维的积累 。Multiple sowing dates, by covering and no covering plastic membrane on soil for 2 cotton verieties were experimented. The results showed that the effects of accomulated temperature on the yield per cotton plant, the qualities of crude fiber in cotton boll and the quantities of crude protein in cotton kernel were significantly direct correlation. The effect of the quantities of crude fiber in cotton boll and the yield per cotton plant were significantly direct correlation, the more accomulated temperature was obtained, the more crude fiber in boll was early acumulated, so as to increase the yield and improve quality by the selection of verieties, the early sow and the cover plastic membrane.
