摘    要:以人工地表补水为对照,观测了针状注射式增压补水对沙土和黄土蒸发的影响,结果表明:补水后6 d内水分蒸发量最大,占总补水量的61.90%;针补后土壤水分总蒸发量仅为地表补水的41.00%,可明显减少土壤水分无效蒸发,提高水分利用效率。

关 键 词:沙土  黄土  补水  无效蒸发  模拟试验

Abstract:We studies on manual-surface water supplement as the check and its dynamic regular simulation based on needle-injection irrigation in the sand and loess soil condition with traditional manual irrigation method.The result showed that the replenishment of water evaporation within the largest total volume of water make up 61.90% after six day;needle-injection irrigation's evaporation quantity is only 41.00% of the traditional manual irrigation method in the same observation period which can significantly reduc...
