摘要
真实节水系指节省在农田水循环中难以回收的水损失(尤其蒸腾、蒸发量)和提高水的转化率。结合黑龙江省水利实践,对节水灌溉(尤其水稻控灌)、井灌、低水位运行,水稻直播栽培等真实节水进行初步研究。
The true water saving is to reduce the water loss on farm water recycle and raise the water transferring rate.This article makes a preliminary research on true water saving methods such as rice irrigation,well irrigation,rice seeding by referring to the Heilongjiang water works practice.
