| 摘 要： | 目前,污水灌溉对作物生长发育的影响日益受到人们的关注。为此,通过水稻盆栽室内实验,着重探讨在不同水污灌溉条件对水稻生长和产量的影响。实验设置了4种灌溉水质(清水、稀释1倍污水、稀释0.5倍污水、污水)对水稻进行灌水处理。结果表明,污水灌溉降低了水稻分蘖率,从而导致最后实际产量下降;但污水对水稻株高、穗长、结实率的提高是有利的。

| Abstract: | A potted experiment was carried out to study the effects of sewage irrigation on growth of paddy. 4 kinds of water quality (tap water, 1 times diluted sewage, 0.5 times diluted sewage and sewage) were set in this experiment. The experimental results indicated that sewage irrigation could reduce the till ring rate and output of paddy. But on the other hand, it was propitious to the growth of stem and starchy. It also could reduce the percentage of sterility. |
