摘　　要：选择新疆伊宁市荒山滴灌造林地,比较研究了8L·h-1和16L·h-1两种不同流量滴头一个灌溉期内土壤水分运移规律,结果表明:伊犁州荒山滴灌造林中使用8L·h-1滴头是合理的,滴头流量过大,容易形成地表径流,造成水资源的浪费;使用8L·h-1流量滴头在造林早期灌溉6~8h就可以保证植物健康生长,随着林分的生长,须逐渐延长灌溉时间。Choosing the forest land by using drip irrigation on barren mountain in Yining City of Xinjiang Uygur Autonomous Region,law of water transport for soil by using two different flow drops(8L·h-1&16L·h-1)were compared in one irrigation period.Result shows that it is reasonable to use8L·h-1drip irrigation emitter in the afforestation on barren mountain in Yili region.It is easy to form surface runoff,resulting in waste of water resources if flow too much of drip irrigation emitter.8L·h-1drip irrigation emitter to drip6-8hours can ensure the healthy growth of plant in the early stage of afforestation.As the stand grow,the irrigation time should be gradually extended

关 键 词：荒山 造林 滴灌 土壤 水分运移
