1、坚持浅水间歇灌溉,增温壮根、促蘖护胎。粳稻在进入分蘖盛期后,稻田水层管理应以浅为主,水层3厘米左右,自然落干至地表无水再行补水,如此反复。抽穗开花期间保持3厘米以下浅水层,促进开花受精,提高结实率;蜡熟期以后采用间歇灌水方式,9月初停止灌水。在孕穗期如气温低 1, insist on shallow water intermittent irrigation, warming strong roots, promote tillering and fetus. After entering the tillering stage of japonica rice, paddy water management should be shallow mainly water about 3 centimeters, naturally dry to the surface without water replenishment, so repeated. During the heading and flowering to maintain shallow aquifer below 3 cm to promote flowering and fertilization and improve seed setting rate; intermittent irrigation after the wax maturing period, stop irrigation in early September. In the booting stage, such as low temperature
