摘　　要：依据田间试验,以西藏高寒作物燕麦、青稞为对象,对于高寒牧区作物水分生产函数的确定进行了初步研究。结果表明,燕麦水分函数模型为Stewart模型,水分敏感程度顺序为:拔节～抽穗、分蘖～拔节、抽穗～刈割、出苗～分蘖;青稞水分生产函数模型为Jensen模型,水分敏感程度顺序为:分蘖～拔节、拔节～抽穗、抽穗～刈割、出苗～分蘖。为西藏高寒地区制定灌溉制度提供了理论依据。According to field trials,alpine crop oats,barley study object.alpine pastoral areas for crop water determination of the production function is studied.The results show that oats moisture function model for the Stewart model,the moisture sensitivity of the order of：jointing-heading,tillering to jointing,heading to mowing,emergence ～ tiller;barley water production function model for the Jensen model,the moisture sensitivity of the order：tillering jointing,jointing-heading,heading to mowing,the emergence ～ tiller.Development of irrigation system serves as a theoretical basis for the alpine region of Tibet.
