摘　　要："水"与"肥"是影响作物生长的最基本的因素,以李子树为供试作物,将水肥调配与测土施肥技术联合应用于日光温室果树栽培试验中,探讨了滴灌条件下该技术水肥效应、节肥效果及其对产量的影响。试验结果表明:各因子对产量影响的顺序为水分>肥料>水肥的交互作用,水肥调配与测土施肥联合技术可节约肥料使用量,同时得出中水中肥处理为该试验的最佳组合。Water and fertilizer are the most basic factors for crop growth. This article through experiment on combined application of water and fertilizer allocation and fertilization by soil test technology for plum in drip irrigation greenhouse explores irrigation and fertilizer utility , fertilizer-saving effect, and influence on yield. The experiment data showed that water, fertilizer and water-fertilizer interaction have obviously effect on yield, and each factor effect on plum yield was water.fertilizer 〉 water-fertilizer interaction. Combined application water and fertilizer allocation and fertilization by soil test technology can effectively save fertilizer usage. At the same time an optimum management plan of water and fertilizer was suggested for high yield based on this design.
