【摘要】 通过对滴灌条件下玉米产量和ＷＵＥ效应的研究，认为在半干旱区玉米上实施滴灌，较畦灌显著节约了水资源，提高了水分利用效率，促进了玉米生长发育，增加了产量。而且在低灌溉量下，较畦灌更稳产，因而对半干旱地区玉米补充灌溉具有十分重要的意义更多还原

【Abstract】 The effect of drip irrigation on yield and WUE of corn were studied under field condition. Results indicated that application of drip irrigation in semi arid corn planting area could not only save water resources,raise WUE,improve growth and development of corn and increase yield but also stabilize yield under low irrigation amount.Therefore,it had very important meaning for supply irrigation of corn in semi arid regions.更多还原
