| 摘 要： | 为了探讨麦田适宜的灌水定额和渠井用水比例,通过采取大田试验,研究冬小麦不同灌水定额、不同渠井用水比例灌溉模式对夏玉米生长发育和土壤盐分的影响。结果表明：纯渠水灌溉能够较好的改变土壤次生盐渍化状况,减少表层土壤含盐量,有利于植物生长。相同渠井用水比例不同灌水定额下,土壤含盐量在出苗期、拔节期、孕穗期波动较大,在灌浆期土壤盐分波动较小。渠井用水比例为0.33、灌水定额为900 m3/hm2处理的夏玉米的百粒重最大。同时,灌水定额太低会抑制夏玉米的生长。

| Abstract: | In order to discuss suitable irrigation quota and percentage of channel and well on cornfield, the experiment was carried out by field to study the effect of different irrigation quota and different percentage of channel and well on the growth of summer maize and soil salinity. The results showed that, channel water irrigation could improve soil secondary salinization, reduce surface soil salinity and be benefit to plant growth. Under the condition of the same percentage of channel and well and different irrigation quota, soil salinity variation was larger in seedling stage, jointing stage and booting stage, but it was small in filling stage. Hundred-grain weight of summer maize was the heaviest when the percentage of channel and well water was 0.33 and irrigation quota was 900 m3/hm2. And the growth of summer maize will be suppressed for low irrigation quota. |
