| 摘 要： | 通过田间试验,以郑单958和浚单20为试材,研究了不同密度和不同灌水处理对玉米产量和水分利用效率的影响。结果表明:不同灌水处理对产量构成影响较小;不同密度下玉米两品种的穗数和穗粒数差异显著;两品种玉米高密度比低密度处理产量平均增加16.89%;抗旱品种郑单958产量受灌水量的影响较小;浚单20灌水比不灌水处理平均增产11.40%。玉米两品种处理水分利用效率一般以不灌水处理较高,灌水处理水分利用效率均值比0水处理降低30.37%。因此,在水资源较缺乏的太行山山前平原区,选用抗旱品种进行合理密植并灌一水,对实现玉米节水与高产的统一有着重要意义。

| Abstract: | A field experiment was conducted to study the effects of different density and irrigation treatments on the water use efficiency(WUE) and yield of two corn cultivars.Results showed that irrigation treatments had the less influence on yield constitute factors.The number of ears per hectare and grains per ear of corn at different densities were significantly different.The yield of high density increased 16.89% than that of low density.Irrigation had the less influence on the yield of Zhengdan 958,which was th... |
