中文摘要	为研究旱作条件下马铃薯不同覆盖材料的土壤水热条件及其对产量与水分利用效率的影响,在大田条件下,设置普通地膜、秸秆、绿肥、液体地膜4种覆盖材料栽培方式,测定其土壤含水量、耕层土壤温度和产量,并计算各覆盖材料的水分利用效率。结果表明,与传统裸地(CK)相比,普通地膜、秸秆、绿肥、液体地膜覆盖材料处理下耕层土壤(025 cm)日平均温度提高3.62,2.01,1.50以及2.38C ;各覆盖材料均可提高土壤含水率,普通地膜、秸秆、绿肥、液体地膜覆盖较对照耕层土壤(025 cm)平均含水率增加3. 25%,2. 24%,2. 40%以及2.50%;与对照相比,各种覆盖材料可使马铃薯块茎产量分别增加10. 33%, 23.03%, 20.27%及27. 17%;不同覆盖材料水分利用效率大小为:液体地膜>绿肥>秸秆>普通地膜>对照(CK)。液体地膜在土壤保水及对马铃薯产量的影响方面均具有显著效果。
英文摘要	In order to explore the water-thermal conditions of different mulching treatments, and their effects on potato yield and water use efficiency in arid and semi-arid area, the field experiment was conducted, which included common plastic film(CPF),straw(S), green manuring(GM),liquid film(LF) and bare land(CK). Soil water content, topsoil temperature, yield and water use efficiency of different mulching treatments were investigated. The results showed that, compared with the conventional tillage technique treatments, CPF, S,GM,LF increased soil daily mean temperature in 025 cm layer by 3. 62C,2. 01 C,1. 50 °C and 2. 38 °C,respectively. The different mulching treatments increased the soil moisture. CPF, S,GM and LF could increased soil water content in 0-25 cm layer by 3. 25%,2. 24%, 2. 40% and 2. 50%, respectively. Compared with CK, the tuber yield with the treatments of CPF, S, GM and LF increased by 10. 33%, 23. 03%, 20. 27% and 27. 17%. The descending order of water use efficiency of different mulching treatments was liquid film, green manuring, straw,common plastic film and CK. Therefore, liquid film had significant effect on soil water conservation and potato yield.
