试验结果表明,沟种移膜能提高5cm 土壤温度3～5℃和0～10cm 土壤含水量2.6%～6.0%,旱地棉花出苗率比平覆地膜、穴播、露地播种、水种包包播种和撵墒播种分别增加10.2%、20.0%、34.1%、39.2%和61.3%。病株率比平覆地膜、平覆沟种减少13.5%～20.3%,死苗率减少15.1%～21.0%.比露地、平覆地膜主根入土深20～30cm,侧根增加5～10条.地膜可连用2～3年,比一般覆膜亩节支17.6元,且减少残膜对土壤环境的污染.
The results showed that the furrow transfer could increase the soil temperature 5 ~ 5 ℃ and the soil water content 0 ~ 10cm by 2.6% ~ 6.0%. The emergence rate of cotton in dry land was higher than that of mulching, hole-sowing and open-field sowing, Moisture seeding increased by 10.2%, 20.0%, 34.1%, 39.2% and 61.3% respectively. The rate of diseased plants was reduced by 13.5% ~ 20.3% compared with that of flat mulch, and the rate of dead seedlings was reduced by 15.1% ~ 21.0% .Compared with open field, Can be used for 2 to 3 years, mu than the average film mulberry branch 17.6 yuan, and reduce the residual film on the soil environment pollution.
