中文摘要	在沙区旱作农田设计了4种种植油菜的垄沟种植试验,观测了其与传统平作下的土壤重量含水率.野外对比观测表明:在油菜生长季内,垄沟种植下土壤的水分含量高于传统平作,尤其在地表0～30cm的耕作层;土壤水分在生长季内呈"双峰双谷"型波动特征,可分为"墒情恢复期--缓慢耗墒期--墒情恢复期--迅速耗墒期--墒情恢复期"五个阶段,迅速耗墒期与油菜的旺盛生长期一致,而该时段垄沟种植下土壤重量含水率较高;在同一深度土层,垄沟种植下土壤水分的变异系数小于传统平作,土壤水分季节速变层和活跃层厚度小,稳定层靠近地表,土壤干湿波动较小.该试验研究可以为调整沙区旱地耕作方式,优化土地利用结构及风蚀防治提供参考.
英文摘要	Four fields were designed to conduct ridge-furrow planting experiment in desert region, and soil gravimetric water content rates of that four fields and a conventional flat - tillage field were observed. Field observations indicated: during rape growing period) soil water contents of ridge - furrow planting fields were higher than that of conventional flat-tillage field, especially in plow layer (0～30cm); The fluctuation of soil moisture showed "two peaks-two valleys" type during rape growing period, and it could be divided into five phases: "soil moisture restoring stage-soil moisture slowly consuming stage- soil moisture restoring stage-soil moisture rapidly consuming stage -soil moisture restoring stage". The soil moisture fast consuming stage was coincided with the quickly growing period of rape, in which soil gravimetric water contents in of ridge-furrow planting fields were higher than that of conventional flat-tillage;Compared with the conventional flat-tillage field, in the same depth layer of the soil) the variation coefficient of ridge -furrow planting fields was smaller, the thickness of fast changing layer and active layer was smaller, the stable layer was closer,to the surface of the soil, and the dry-wet fluctuation of the soil was smaller. This experimental research could provide references to adjusting tillage measure of rainfed field, optimizing land use structure, and preventing wind erosion in desert region.
