【摘要】：为研究可降解地膜对渭北旱塬土壤环境及作物生产的影响,设置厚0.008mm可降解地膜、厚0.006mm可降解地膜、普通地膜、露地对照4个处理,分析各处理对玉米田土壤温度、水分及产量和相关因子的影响。结果显示,播种后0~80d,3种覆膜处理5、10cm土壤温度和0~30cm土壤水分显著高于露地对照,且厚0.006mm可降解地膜和普通地膜间差异不显著(P0.05);同时,两处理产量分别达到10 020.00kg/hm~2和10 245.60kg/hm~2,两者间差异也不显著(P0.05),但均明显高于厚0.008mm可降解地膜处理和露地对照。说明,厚0.006mm可降解地膜增温保墒及增产效果与普通地膜相当,可在实践中应用。
[Abstract]:In order to study the effect of degradable plastic film on soil environment and crop production in Weibei dryland, four treatments, thick 0.008mm degradable plastic film, thick 0.006mm degradable plastic film, common mulching film and open field control, were set up to analyze the soil temperature of maize field under each treatment. Effects of moisture, yield and related factors. The results showed that the soil temperature and 0~30cm soil moisture of the three film mulching treatments 10 cm after sowing were significantly higher than those of the open field control, and there was no significant difference between the thick 0.006mm degradable mulching film and the common mulching film (P0.05). At the same time, the yield of the two treatments reached 10 020.00kg/hm~2 and 10 245.60 kg / hm ~ (2), respectively, and the difference between the two treatments was not significant (P0.05), but both were significantly higher than that of thick 0.008mm degradable plastic film treatment and open-field control. The results showed that the effect of thick 0.006mm degradable mulching film on increasing soil moisture and increasing yield was similar to that of common mulching film, and could be applied in practice.
