摘　　要：在陕北神木,设置带型150 cm(DX1)、带型120 cm(DX2)、带型80 cm(DX3)、双沟覆膜(DX4)、平膜穴播(DX5)、露地平作(CK)6种微集水种植模式,观测各模式对绿豆产量及水分利用效率的影响。结果表明,与露地平作相比,微集水种植模式条件下土壤表层(0～40 cm)含水量高,绿豆生育期提前,叶面积、生物量和叶绿素含量显著增加;不同微集水模式中,双沟覆膜(DX4)集水效果最为明显,绿豆籽粒产量及水分利用效率分别较对照提高24.5%和32.88%,DX5、DX3、DX2、DX1差异均达到显著水平。因此,微集水技术具有较好的聚雨保墒效果,能明显提高绿豆籽粒产量及水分利用效率。A field experiment was conducted to determine the effects of mode 150 cm（DX1）,mode 120 cm（DX2）,mode 80 cm（DX3）,film-covered double-furrow（DX4）,flat filmcovered（DX5） and traditional cultivation（CK） six micro-water-harvesting techniques on soil water use efficiency and grain yield of mung bean in Shenmu,the northern of Shaanxi.The results show that there are obvious effects of micro-water-harvesting techniques compared with traditional cultivation（CK）.They can significantly increase water storage capacity in the 0～40 cm soil layer,as well as speed up growth and leaf area,biomass and chlorophyll content.The DX4 has the best effect,in which the grain yield and water use efficiency increase by 24.5% and 32.88%,while DX5,DX3,DX2 and DX1 are also up to remarkable level.Therefore,the micro-water-harvesting techniques have large water storage capacity and can increase grain yield and water use efficiency.
