水稻采用节水灌溉技术，比同等条件下常规灌溉技术，每667平方米稻田节约用水150～200立方米，增产稻谷60～80千克。1．浅水栽秧浅水一般以花花水至3．3厘米为宜。由于浅水栽秧时能达到稳、匀、浅、端，无浮秧，成活快，返青早，秧苗活棵后，适当加深水层3．3～5厘米，以利返青 Rice uses water-saving irrigation technology, which saves 150 to 200 cubic meters of water per 667 square meters of paddy fields and 60 to 80 kg of paddy more than conventional irrigation techniques under the same conditions. 1. Shallow shallow water seedlings generally spend flowers to 3.3 cm is appropriate. As shallow water seedling can reach the stable, uniform, shallow, end, no floating seedling, fast-growing, early greening, seedling seedling, appropriate to deepen the water layer 3.3 to 5 cm, to facilitate greening
