【摘要】：為研究可降解地膜對渭北旱塬土壤環(huán)境及作物生產(chǎn)的影響,設(shè)置厚0.008mm可降解地膜、厚0.006mm可降解地膜、普通地膜、露地對照4個處理,分析各處理對玉米田土壤溫度、水分及產(chǎn)量和相關(guān)因子的影響。結(jié)果顯示,播種后0~80d,3種覆膜處理5、10cm土壤溫度和0~30cm土壤水分顯著高于露地對照,且厚0.006mm可降解地膜和普通地膜間差異不顯著(P0.05);同時,兩處理產(chǎn)量分別達到10 020.00kg/hm~2和10 245.60kg/hm~2,兩者間差異也不顯著(P0.05),但均明顯高于厚0.008mm可降解地膜處理和露地對照。說明,厚0.006mm可降解地膜增溫保墑及增產(chǎn)效果與普通地膜相當(dāng),可在實踐中應(yīng)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.
