水稻间断灌溉是继浅湿灌溉之后出现的又一种科学灌溉制度。其主要特点是,在水稻移栽后,全生育期灌水次数少(9～12次),田间净灌溉定额低(每亩350～450方)。与常规灌溉方法相比,间断灌溉灌水次数减少75％左右,节水20～30％,水的生产效率提高15～20％。大面积试验和示范表明,实行间断灌溉的水稻,单产达千斤以上。
Intermittent irrigation of rice is another scientific irrigation system following shallow wet irrigation. Its main feature is that after transplanting rice, irrigation times in the whole growth period are less (9 ~ 12 times), and the net irrigation quota in the field is low (350 ~ 450 sides per acre). Compared with conventional irrigation methods, the number of intermittent irrigation and irrigation is reduced by about 75%, water saving is 20-30% and water production efficiency is increased by 15-20%. Large-scale experiments and demonstration show that the implementation of intermittent irrigation of rice, yield more than a kilogram.
