本省连作晚稻,一般在大暑前后插秧,处暑边拔节,秋分前后齐穗,立冬前后成熟。在这100—120来天的本田生育期间,“水”是保证连作晚稻健壮生育、获得丰产的重要物质基础。缺水固然不可,灌水不合理也会严重地影响其生长发育。因此,必须讲究合理灌排,保证有良好的水分条件,才能充分发挥增产潜力,达到今年连作晚稻持续大跃跃。一、连作晚稻的需水量和需水规律研究连作晚稻的需水量和需水规律,除能控制水分供应狀况,促进水稻健壮生育外,在战胜干旱、保证水稻用水和最大程度地发挥农田灌溉效益方面,也 Even the late rice crop in the province, generally transplanting before and after the summer weather, the Department of summer and jointing section, autumn and winter before heading, ripe winter before and after legislation. During the 100-120 days of Honda’s birth, “water” is an important material basis for ensuring continuous crop growth and harvesting in late rice. Water short of course, irrational irrigation will seriously affect its growth and development. Therefore, we must pay attention to rational irrigation and drainage, to ensure that there is a good water conditions in order to give full play to the potential yield increase, reaching even this year as a continuous big leap forward late rice. First, continuous cropping of late rice water demand and water demand Law Continuous cropping water demand and water demand patterns, in addition to controlling the water supply and promote rice robust growth, the fight against drought, ensure rice water and maximize farm irrigation Benefit, too
