摘　　要：利用微集水种植技术,在我国北方旱作农业地区开展节水灌溉种植,研究不同微集水种植技术对该地区土壤水分的影响。研究结果表明:在不同降水年份,相对于传统种植模式,各微集水种植模式能够明显提高土壤蓄水保墒效果,在玉米生育期内,微集水处理在0-160cm土层的蓄水量要好于传统种植模式。Study on water saving irrigation cultivation in dry farming areas of northern China by using microcatchment cultivation technology.The paper analyzed the influence of micro-catchment cultivation technology on soil moisture in the region.The results show that in different rainfall years,compared with the traditional planting patterns,the micro-catchment cultivation technology patterns can obviously improve the effect of soil water storage.During the maize growth period,micro-catchment cultivation in 0-160 cm soil storage capacity is better than the traditional.
