中文摘要：
为了探讨小畦膜上灌对玉米生理特性、水分利用效率及产量等的影响,在宁夏引黄灌区进行了田间对比试验。结果表明小畦膜上灌玉米株高、生长速度、叶面积指数、干物质积累量、作物群体生长率、秸秆充实度、光合势、果穗重、千粒重、穗长、穗行数、行粒数均优于小畦灌溉处理的玉米,产量也显著高于小畦灌溉,增产幅度达到12.11%,其水分生产率比小畦灌溉提高了5.93%,净效益比小畦灌溉高5.99%。
英文摘要：
In order to ascertain influence on physiological characters,water use efficiency and yield of maize under border irrigation with film,the field check experiment was carried out in Ningxia irrigation area diverting water from Yellow River.The results showed that plant height,growth rate,leaf area index,dry matter accumulation,crop growth rate,stem substantial degree,leaf area duration,ear weight,thousand-seed weight,ear length,ear rows and kernel numbers per row of maize under border irrigation with film was superior to check plot.Yield of maize under border irrigation with film was significant higher than check plot,the rate of yield increase attain to 12.11 percent.Water use efficiency of maize under border irrigation with film was higher 5.93 percent and net benefit was higher 5.99 percent than corresponding index in check plot under border irrigation without film.
