摘要/Abstract

摘要： 为综合量化评价新疆地膜覆盖对主要作物产量和水分利用效率的影响，应用Meta-analysis方法，定量分析地膜覆盖后作物产量和水分利用效率的变化，并探讨其影响因素。通过文献检索（1982—2019年），共获得347篇有关新疆主要作物地膜覆盖试验文献。经严格筛选，从52篇文献中获得208组数据，分布于新疆18个市、县，涵盖南疆和北疆2个主要区域。结果表明：地膜覆盖可显著提高作物产量（24.1%）和水分利用效率（26.0%），甜菜、向日葵、玉米、棉花、小麦和大豆分别增产38.1%、29.5%、29.4%、26.4%、17.6%和15.8%；玉米、棉花和小麦水分利用效率分别增加32.0%、27.3%和13.7%；在地域上，南疆增产幅度大于北疆地区；在相对较差的土壤基础肥力中表现出较好的增产效应和水分利用效率增加效应；年均降水量<200 mm与年均降水量≥200 mm区域相比，有较高的增产效应，年均气温≥10 ℃的区域较年均气温<10 ℃的区域增产幅度大，相对未覆盖地分别增产31.8%和27.6%；低海拔地区<500 m与高海拔地区≥500 m相比，增产效果更显著；水分利用效率在年均气温<10 ℃、年均降水量<200 mm和高海拔地区增加效应最明显。该研究可为新疆覆膜技术应用提供参考。

Abstract: To comprehensively and quantitatively evaluate the effects of plastic film mulching on yield and water use efficiency of main crops in Xinjiang, a metaanalysis was conducted to quantitatively analyze changes in yield and water use efficiency of main crops after plastic film mulching. The influencing factors were discussed. Through literature search (from 1982 to 2019), a total of 347 related papers were obtained. After strict screening, a total of 208 data sets were obtained from 52 papers, which were distributed in 18 cities and counties in Xinjiang and covered two main regions of Southern Xinjiang and Northern Xinjiang. Results showed that plastic film mulching significantly increased the yield (24.1%) and water use efficiency (26.0%) of crops. The yield of beet, sunflower, corn, cotton, wheat, and soybean increased by 38.1%, 29.5%, 29.4%, 26.4%, 17.6%, and 15.8% respectively; while water use efficiency of corn, cotton, and wheat increased by 32.0%, 27.3%, and 13.7% respectively. Geographically, the yield enhancement in Southern Xinjiang was greater than that in Northern Xinjiang. Higher enhancement of both yield and water use efficiency was found in relatively poor original soil fertility. There were higher yield increasing effects in areas with mean annual precipitation of <200 mm than those with mean annual precipitation of ≥200 mm. The increase in yield was higher in areas with a mean annual temperature of ≥10 ℃ than those with a mean annual temperature of <10 ℃, with an increase of 31.8% and 27.6% compared to unmulched areas, respectively. The yield increasing effects were more significant in low-altitude areas of <500 m compared with those in high-altitude areas of ≥500 m. The increasing effects of water use efficiency were most obvious in areas with a mean annual temperature of <10 ℃, mean annual precipitation of <200 mm, and high-altitude. This study can provide a reference for the application of plastic film mulching technology in Xinjiang.
