中文摘要	2013~2015年在黄土高原半干旱区以传统平作不覆盖为对照(CK)、地膜全覆盖(PA)、可降解膜全覆盖(BA)、玉米秸秆全覆盖(SA)和沟垄集雨半膜覆盖(RH)4种覆盖方式,研究不同秋季覆盖方式的土壤水分保蓄效果及对春玉米生长的影响。结果表明,在冬春休闲期,PA、BA、SA、RH处理均能有效提高播种前土壤水分,SA和RH处理在整个生育期土壤蓄水量显著高于CK,PA和BA处理仅在生育前期有较高的土壤水分;PA、BA和RH处理均有增温效果。不同处理中,PA处理产量最高,2年平均较CK提高58.17%,RH与BA处理分别较CK提高34.16%和27.05%,SA处理低于CK;水分利用效率与产量规律一致,PA、BA和RH处理分别较CK提高36.89%、14.34%和29.51%。
英文摘要	From 2013 to 2015, we conducted a field experiment in the semi-arid areas of Northwest China to determine the effects of different mulching patterns on the capacity of soil water-holding and spring maize growth. Five treatments were included, flat planting without mulching(CK); plastic film mulching during the whole season from previous autumn(PA); degradable film mulching during the whole season from previous autumn(BA); corn straw mulching during the whole season(SA); alternating ridges and furrows with the ridges mulched with plastic film during the whole season(RH). The results showed that during the fallow period of winter, the four mulching patterns, PA, BA, SA, RH, were all benefit for the soil water storage compared with CK, and SA and RH functioned during the whole growth season, while PA and BA worked well only at the early growth stage. The mean soil temperature(5- 25 cm) under PA, BA and RH treatments were all higher than that of CK. In addition, PA, RH, and BA resulted in relatively higher maize yield and higher water use efficiency throughout the whole experimental period. Compared with CK, the PA, RH, and BA treatments increased the two-year mean maize yield by 58.17, 34.16, and 27.05%, re- spectively, and improved the water use efficiency by 36.8, 14.34, and 29.51%, respectively.
