晚稻拔节之后,便陆续进入孕穗时期。孕穗期水稻的营养生长和生殖生长都处在旺盛时期,水肥的吸收量最大,病虫害的防治任务重。为了夺取晚稻丰收,应该做到以下三点。1.保证水分晚稻孕穗期的气温处于较高温度,田间的水分蒸发量大。水分供应十分重要。这是因为,孕穗期是水稻一生中水分吸收量最大的时期,也是对水分最敏感的时期,充足的水分供应能够满足幼穗发育, After late rice jointing, they gradually entered the booting period. Booting stage of rice vegetative growth and reproductive growth are in a strong period, the largest absorption of water and fertilizer, pest control and heavy task. In order to win the late rice harvest, we should do the following three points. 1 to ensure that water temperature at late booting stage of rice at a higher temperature, the field of large amount of water evaporation. Water supply is very important. This is because the booting stage is the period in which rice has the largest amount of water uptake during the lifetime and is also the period most sensitive to water. Sufficient water supply can meet the needs of young panicle development,
