| 摘 要： | 为了利用有限的水资源，采用膜下滴灌方式达到高效利用的目的，对玉米膜下滴灌适宜补灌量进行研究。结果表明，覆膜保墒技术与膜下滴灌（补灌）技术相结合是旱地玉米较为理想的种植方式，可以提高水分有效利用率，改善玉米生长微环境，有效促进玉米个体生长发育，增加群体产量。建议在水资源较缺乏的旱作区发展膜下滴灌种植玉米，全生育期滴水量1350或1050m^3／hm^2。

| Abstract: | In order to utilize the limited water resources, using the drip irrigation mode under membrane to achieve the purpose of efficient use, irrigation quantity research on drip irrigation under membrane of corn was studied. The results showed that the effect of soil conservaton drip irrigation technology and drip irrigation under membrane was ideal cultivation mode of dry land corn, which could improve the effective of water utilization, improve maize growth microenvironment, effectively promote the corn individual growth and development and increase the population yield. The study suggested that water drops of drip Irrigation under membrane of corn in the whole stages was 1 350 or 1 050 m^3/hm^2 in dry farming areas. |
