塑料薄膜覆盖栽培,是目前提高棉花单产的一项重要技术措施。特别是对无霜期短、有效积温较低、地下水位高、土壤次生盐渍化较重的地区,采用塑膜覆盖栽培棉花,增产效果更为显著。1981年我团场首次大面积推广了地膜植棉,种植面积4,155亩,取得了较好的增产效果,平均单产皮棉达142.5斤,有503亩单产皮棉在200斤以上;产量最高的一块6.1亩单产314.1斤,改观了我场一向植棉单产只有几十斤的落后面貌。经调查对比,地膜棉花较常规栽培棉花增产87.2％,充分显示了它的增产潜力。 Plastic film covering cultivation, is to improve cotton yield an important technical measure. Especially for frost-free period is short, the effective accumulated temperature is low, high groundwater levels, soil secondary salinization heavier areas, the use of plastic film covered cultivation of cotton, yield more significant effect. In 1981, for the first time in our field, a large area of ​​plastic film cotton was popularized, covering 4,155 mu of cultivated area and achieved good yield increasing effect. The average yield of lint cotton was 142.5 kg, and 503 mu of lint cotton was over 200 kg. The highest yield of 6.1 mu Yield 314.1 kg, changed my field has always been cotton yield only a few pounds of backwardness. After investigation and comparison, mulching cotton yield 87.2% more than conventional cotton cultivation, which fully shows its potential for increasing production.
