摘　　要：在辽宁昌图冷凉风沙区采用双沟覆土压膜方式进行花生栽培试验,以传统覆膜方式作为对照。试验结果表明:双沟覆土压膜方式降低人工引苗率,对照的人工引苗率为88.5%,而双沟覆土压膜方式仅7.7%。双沟覆土压膜方式花生出苗率较对照提高19.4%;根际土壤含水量较对照高3.6~19.8个百分点。双沟覆土压膜方式花生单株分枝数、主茎高、第一侧枝长、根系干重和茎叶干重等植株长势指标明显高于对照;荚果产量、百仁重和出仁率等产量及产量性状,分别提高18.7%、5.8%和2.6%。冷凉风沙地区,花生采用双沟覆土压膜方式栽培,幼苗出苗率高,根际土壤水分含量增加,植株长势增强,产量提高,饱果率、百果重、百仁重增加。The peanuts were cultivated by double ditch and film mulching pressed with soil in the cool and breeze sand area of Changtu county Liaoning province,the traditional film mulching method was used as the control.Compared with the control,double ditch and film mulching pressed with soil treatment significantly reduced the artificial emergence rate of peanuts.The artificial emergence rate of peanuts in the control was 88.5%,while that of peanuts in double ditch and film mulching pressed with soil treatment was 7.7%.Pea-nuts seeding emergence rate of double ditch and film mulching pressed with soil treatment was 19.4%higher than that in the control,and soil moisture contents were 3.6~19.8 percentage points higher than that in the control.Compared with the control,double ditch and film mulching pressed with soil treatment enhanced the plant branches number,main stem height,first pair of branches length,and the biomass of root,stem and leaf.Pods yield,100-kernels weight and kernel ratio in double ditch and film mulching pressed with soil treat-ment were 18.7%,5.8%and 2.6%higher than that in the control.The results indicated that double ditch and film mulching pressed with soil treatment could increase the peanuts seeding emergence rate,soil moisture content,plant growth,filed yield,full fruit rate,100-pods weight and 100-kernels weight than the control in the cool and breeze sand.
