水稻后期是重要的生产时期,要注意做好相关管理措施。合理施肥在水稻生育中后期要控制氮肥用量,对脱肥、落黄稻田应采取少吃勤餐的方法,看苗补肥,要追肥和叶面肥结合作用。合理浅灌以浅水灌溉为主,实行浅—湿—干间歇灌溉的原则,从而达到以水养根,以根保叶,活秆成熟。在孕穗期如遇17℃以下低温,应灌15厘米深水护胎防止冷害;抽穗开花期保持浅水层,灌足生态需水;灌浆期开始间歇灌溉,改善土壤的通气状况,增强根系活力,促进叶的功能达到活秆成熟;到黄熟期停灌。
Late rice is an important period of production, pay attention to the relevant management measures. Rational fertilization in the late rice growth to control the amount of nitrogen fertilizer on the de-fertilization, falling yellow paddy should take less eating and dunking methods to see seedling fertilizer, fertilizer and foliar fertilizer to be combined. Reasonable Shallow Irrigation shallow irrigation, the implementation of the principle of shallow - wet - dry intermittent irrigation, so as to recuperate with water to root Paul leaves, mature live straw. At the booting stage in the case of low temperature below 17 ℃, 15 cm deep water should be infused to prevent chilling damage; heading and flowering to maintain shallow water layer, irrigation foot ecological needs; intermittent irrigation filling period to improve soil aeration, enhance root activity and promote The function of leaves to live straw mature; to stop the irrigation of yellow ripening.
