中文摘要	基于2a田间试验数据,对比研究了不覆盖(CK)、垄覆白膜沟不覆盖(M1)、垄不覆盖沟覆秸秆(M2)、垄覆白膜沟覆秸秆(M3)和垄覆黑膜沟覆秸秆(M4)5种集雨模式对农田土壤水热状况及夏玉米产量和水分利用效率的影响。结果表明,垄沟覆盖集雨措施可显著提高土壤贮水量、土壤含水率及土壤储水亏缺补偿度(P<0.05),其中全程覆盖处理(M3和M4)优于单一覆盖处理(M1和M2),垄覆黑膜处理(M4)优于垄覆白膜处理(M3)。黑色地膜较白色地膜可显著降低膜下(除表层)土壤温度(P<0.05);沟内覆秸秆较沟内无覆盖可有效改善根层土壤温度。M4处理较优的水热条件可显著提高玉米经济产量和水分利用效率(P<0.05),其2a平均籽粒产量和水分利用效率分别较处理CK提高30.90%和57.49%,是陕西关中地区合理有效的集雨模式。
英文摘要	Two-year (2013 and 2014) field experiment was carried out to increase rainfall utilization efficiency and improve soil water availability for crops in arid area. A total of five treatments (CK: ridge-furrow planting without mulching over both ridge and furrow; M1: ridge-furrow planting with transparent film mulching over ridge only; M2: ridge-furrow planting with corn straw mulching over furrow only; M3: ridge-furrow planting with transparent film mulching over ridge and corn straw mulching over furrow; M4: ridge-furrow planting with black film mulching over ridge and corn straw mulching over furrow) were chosen to investigate the effects of different rainwater harvesting patterns on soil hydrothermal regimes, yield and water use efficiency of summer maize. The results showed that rainwater harvesting treatments could improve soil water storage, soil moisture content and compensation degree of soil water storage deficit significantly (P<0.05). The treatments with mulching over both ridge and furrow (M3 and M4) were superior to the treatments with mulching either over ridge or over furrow (M1 and M2). And treatment M4 was better than treatment M3. Compared with transparent film mulching over ridge, black film mulching over ridge could reduce the temperature under film (P<0.05). In contrast to no mulching over furrow, corn straw mulching over furrow could optimize the heat condition around roots. With improved soil water and temperature conditions, the treatment of ridge-furrow planting with black film mulching over ridge and corn straw mulching over furrow (M4) could increase yield and water use efficiency of summer maize to a great extent. Compared with CK, the average yield and water use efficiency of M4 in 2013 and 2014 were increased by 30.90% and 57.49%, respectively. In conclusion, treatment M4 was the appropriate rainwater harvesting pattern for summer maize cultivation in Guanzhong Region, Shaanxi Province. The results could provide valuable information for selecting efficient rainwater harvesting pattern in semi-arid regions of China.
