摘要
为了验证滴灌技术在玉米种植上的应用效果，对玉米滴灌技术效益进行研究。结果表明，膜下滴灌技术较露地滴灌种植增产12．9％，增收1917元／hm^2，水分利用效率增加13．9kg／（mm·hm^2），提高25．6％；比常规灌溉种植增产21．5％-27．5％，水分利用效率增加50．45-50．98kg／（mm·hm^2）。
In order to verify the application effect of drip irrigation technology in corn, drip irrigation efficiency of the corn were studied. The results showed that yield increased by 1 917 yuan/hm^2 than open field drip irrigation euhivation, the increase rate being 12.9%. Water use efficiency increased by 13.9 kg/ （mm·hm^2）,the increase rate being 25.6%; The yield increased by 21.5%-27.5% than normal irrigation cultivation, water use efficiency increased by 50.45-50.98 kg/（mm·hm^2）.
