中文摘要	在北疆地区开展非充分灌溉试验,分析北疆干旱荒漠地区主要人工草地在不同土壤水分条件下的作物产量,确定了紫花苜蓿、苏丹草和青贮玉米的水分生产函数模型,并分别采用Jensen模型、Stewart模型和Jensen模型得出了各生育阶段的敏感指数和敏感系数。检验结果表明,所确定的模型有较高的精度,平均相对误差为6.51%、9.24%和9.25%。该研究结果可为合理开发阿勒泰草原乃至新疆牧区有限的水土资源提供理论和技术支撑。
英文摘要	The goal of traditional irrigation is to provide proper moisture for crops and to get the highest yield per unit area. However, on background of water deficits and associated economics in the arid desert regions of Northern Xinjiang, relations between water input and crop yield have become a hot topic. In this study, insufficient irrigation test was carried out in the northern region, and the yields of alfalfa, Sudan grass and silage corn were analyzed under different soil water conditions, and the water production function model of these artificial grasslands was determined; meanwhile, the water sensitivity index or coefficient for alfalfa, Sudan grass and silage corn in each growth stage was calculated by using Jensen model, Stewart model and Jensen model, respectively. The test results showed that the models had a high precision, and the average relative errors for alfalfa, Sudan grass and silage corn were 6.51%, 9.24% and 9.25%, respectively. The research results can provide theoretical and technical support for the rational development of limited water and soil resources in Altay grassland and pasture of Xinjiang.
