摘　　要：通过盆栽试验,对玉米不同灌水处理下的耗水量和产量的试验资料进行回归分析,建立了Jensen模型、Minhas模型,Blank模型、Stewart模型和Singh模型,对上述5种水分生产函数模型求解结果进行比较分析与评价,确定适合黑龙江省西部半干旱区的玉米水分生产函数模型为Jensen模型和Stewart模型,可为该地区玉米非充分灌溉条件下的灌溉制度优化提供基础依据。Through the means of the pot-grown test, Jensen model, Minhas model, Blank model, Stewart model and Singh model were established to regress on consumed water quantity and the yield of maize of the different irrigated. To analyze and evaluate above-mentioned models, Jensen model and Stewart model were regard as the more suitable model in semiarid area of the west region of Heilong- jiang Province. This experimental result provides a scientific basis for optimum irrigation schedules of maize under the deficient irrigation of this area.
