中文摘要	研究了旱作区雨养条件下,不同覆盖栽培模式对农田土壤水热变化动态及夏玉米产量的影响,为完善覆膜集雨栽培技术提供了一定的理论依据。试验设置了宽窄行垄沟覆膜种植(WFL)、宽窄行平作覆膜种植(WFP)、等行距垄沟覆膜种植(DFL)、等行距平作覆膜种植(DFP)、等行距平作不覆膜种植(CK)等5种不同种植模式,分别监测作物全生育期的土壤水分和土壤温度。结果表明,各覆盖处理0~10 cm土层有效积温(TT_(soil))均显著增加,整个生育期内,WFL、DFL、WFP和DFP处理的TT_(soil)较CK分别提高280.2、250.2、162.3和150.5 ℃(P<0.05)。覆盖种植使玉米生育期提前,且延长了玉米的生殖生长期,WFL、DFL、WFP和DFP处理玉米的生殖生长时间分别较CK长19、14、16、12 d。各覆盖处理均能改善玉米前期0~200 cm土层土壤水分,其中,WFL处理在0~20 cm土层内土壤储水量增加最为显著,较CK提高了21.95%。玉米生长后期各处理土壤贮水量与CK无显著差异。与等行距垄沟种植模式相比,宽窄行垄沟覆盖模式促进了个体发育,增加了叶面积指数和干物质积累,作物产量提高13.8%,水分利用效率提高了6.8%,土壤有效积温利用效率提高47.2%,各项指标与CK差异均达极显著水平。因此,宽窄行垄沟覆盖模式可推荐为旱作区一种较为理想的保护性耕作模式。
英文摘要	In order to explore the effects of wide ridge and narrow row with ridge mulching mode on soil water content, soil temperature and yield of summer maize. Five experimental treatments were set as follows: ①Wide ridge and narrow row with ridge mulching cultivation (WFL); ②Wide-narrow row flatten culture with wide row mulching cultivation (WFP); ③Equal row spacing with ridge mulching cultivation (DFL); ④Equal row spacing flatten culturewith interlaced mulching cultivation (DFP); ⑤ Flatten culture without mulching as the control (CK). Soil water content and soil temperature during the growth season of summer maize were monitored by TRIME-TDR and the thermometers. There was a significant increase in soil temperature (0~10 cm layer) under film mulching treatments. Compared with CK, the TT_(soil) was increased by 280.2, 250.2, 162.3, 150.5 ℃(P<0.05) in the whole growth stage of summer maize with the treatments of WFL, DFL, WFP and DFP. The maize reproductive stage was prolonged with all film mulching treatments. Respectively, it was increased by 19, 14, 16, 12 d with WFL, DFL, WFP and DFP treatments. In addition, soil moisture of the various rainwater harvesting treatments was also improved in the early growth of maize, especially with WFL treatments, soil water content was improved by 21.95% compared to CK. There was no difference in soil moisture among all treatments during the middle and late growth stages of summer maize. Compared with the equal row with ridge-cultivation, the growth and development of the dry matter accumulation and LAI of maize plants were improved effectively of the widenarrow row with wide-ridge mulching cultivation, and the yield, the soil water use efficiency and the soil temperature were increased by 13.8%, 6.8% and 47.2%, respectively. Compared to CK, WFL showed highly significant difference in all the indexes. Wide-narrow row with ridge mulching was recommended as an ideal model of conservation tillage in the arid region.
