为了摸索在盐碱地植棉夺取全苗的措施,对我团盐碱较重的五分场的地膜保全苗经验进行了全面调查,发现该分场采用膜孔点种盖砂保全苗效果较好。凡是采用细砂盖膜孔的出苗率达98.8％以上,较未盖砂的提高3.6％。该分场一九八三年的5,942亩地膜棉普遍采用膜孔盖砂,亩保苗株数平均达8,806株,较1,275亩普通棉花亩保苗5,645株提高55.9％,单产较普通棉花增产66.6％。
In order to explore the cotton planting in saline-alkali to capture the whole seedling measures, I regiment of saline-alkali five-field mulching seedling experience of a full investigation and found that the use of membrane holes in the sub-site cover saponins seedlings better. Any use of fine sand cover film hole rate of more than 98.8%, compared with uncapped sand increased by 3.6%. Covering 5,192 mu of membrane mulching clay in 1983, the average number of mulberry seedlings per mu was 8,806, an increase of 55.9% over 5,675 mou of 1,275 mou of ordinary cotton. The yield per unit area was 66.6% higher than that of ordinary cotton.
