为了提高玉米对土壤水分的利用率，以玉米为试验材料，在自然条件下，通过灌溉和非灌溉对比研究，分析不同土壤湿度对玉米生长发育及产量的影响。结果表明：试验田表层（0～30 cm ）与深层（30～50 cm ）土壤水分随时间的波动趋势相似，但表层土壤更易受外界影响。生育期内不同土壤湿度对玉米生长性状、干物质重及产量影响显著。灌溉处理为玉米生育期提供了更适宜的土壤水分，利于玉米地上干物质的累积，玉米进入乳熟期后，适当地灌溉更有利于稳产高产。

In order to improve utilization of soil moisture in maize production ,taking maize as experimental material ,the effects of different soil moisture content on growth and yield of maize were studied by comparison observation for irri-gation and non-irrigation .The results showed that the soil moisture fluctuation trends were similar between surface layer(0~30 cm)and deep level(30~50 cm)in the test field ,but the surface layer was more easily influenced by the outside factors .Different soil humidity had significant effects for maize growth ,dry weight and yield during growth pe-riod .Irrigation provided more water in favor of dry matter accumulation on the ground .Appropriate irrigation was more conducive to the stable and high production of maize after milk stage .
