| 摘 要： | 污水灌溉对作物生长和土壤环境的影响倍受研究人员的关注。通过在北京东郊所进行的清、污水灌溉田间试验 ,着重探讨了污灌条件下 ,不同灌水水平和施肥量对夏玉米生长和产量的影响。结果表明 ,与清水灌溉相比 ,污水灌溉 :1对夏玉米的生长发育具有一定的抑制作用 ;2对夏玉米的产量和干物质量的影响要大于对株高和叶面积指数的影响 ;3无肥处理比施肥处理的产量要高 5 .2 %。

| Abstract: | A field experiment was conducted with two kinds of irrigation water, sewage and fresh water. The effects of irrigation water quality, irrigation quota, and fertilizer application level on leaf area index, plant height, dry matter, and yield were investigated. Experimental results indicated that sewage water irrigation may restrained summer corn growth in some extent. Contrasting to fresh water irrigation, sewage water irrigation: ① restrained the growth of summer corn to a certain extent; ② the influence on the yield and dry material is comparatively greater than that of sewage water irrigation on height and index of leaf area; and ③The yield of non fertilizer treatment plots is 5.2 per cent greater than that of fertilized ones. |
