摘　　要：黄土丘陵旱坡地 ,采用坡面汇流、水平沟集流和旱井蓄流的系统集水工程积蓄径流营建隔坡水平沟枣树密植园 ,具有较高的生态、经济和社会效益 ,形成了集径流、有机旱作、密植丰产于一体的新的枣树栽培模式。8年生枣树密植园净收入达到 80 5 99.5元 /hm2 ,投资回收期仅为 3.1a ,投入产出比为 1∶4.35 ,初盛果期每年的投入产出比为 1∶7.0 。In loess hill arid hillside field, the jujube close planting garden of level ditch at an interval of slope built through water-collecting engineering of using slope surface to converge, ditch to gather, and water-retention well to store up run off has higher ecological, economic and social benefits, which forms a new cultivating pattern of combine organic farming in arid field, runoff collecting and close planting and high yield in all. The net income per hectare of 8-year-old jujube close planting garden reached 80 599.5 yuan, payout period of investment is only 3.1 years, the ratio of input to output is 1 to 4.35, and it is 1 to only 7.0 in early flourishing phase each year, economic benefit is very remarkable.
