摘　　要：为筛选出适宜延安玉米间作马铃薯模式,试验设置糯玉米新品种万瑞2000号分别与3种不同熟性的马铃薯品种间作,糯玉米万瑞2000间作LK99(M_(1)),万瑞2000间作冀张薯8号(M_(2)),万瑞2000间作陇薯7号(M_(3)),分析其生态效益和经济效益。结果表明:0-100 cm土层含水量,M_(1)>M_(3)>M_(2);水分利用效率,M_(3)>M_(1)>M_(2),M_(3)具有更好的水分生态效益;间作模式玉米产量,M_(1)>M_(2)>M_(3);间作模式马铃薯总产量,M_(1)<M_(2)<M_(3);商品薯率,M_(1)>M_(2)>M_(3);间作模式总产量和水分利用效率,M_(1)<M_(2)<M_(3)。说明在玉米间作马铃薯模式中,玉米与马铃薯晚熟品种间作可获得良好生态效益和经济效益。To choose the suitable intercropping mode of maize and potato in Yan’an,the new waxy maize variety Wanrui 2000 is intercropped with three potato varieties with different maturity,waxy maize Wanrui 2000 intercropped with LK99(mode 1),Wanrui 2000 intercropped with Jizhangshu 8(mode 2),and Wanrui 2000 intercropped with Longshu 7(mode 3).The ecological and economic benefits are analyzed.The results show that the water content of 0~100 cm soil layer is mode 1>mode 3>mode 2;water use efficiency,mode 3>mode 1>mode 2,and mode 3 has better water ecological benefits;maize yield of intercropping mode,mode 1>mode 2>mode 3;The total potato yield of intercropping mode,mode 1<mode 2<mode 3;the commodity potato rate,model 1>model 2>model 3;the total yield and water use efficiency of intercropping mode,mode 1<mode 2<mode 3.It shows that in the maize intercropping potato model,the intercropping of maize and potato late-maturing varieties can obtain good ecological and economic benefits.
