今年早稻栽插后,南方多日连降大雨和暴雨,不少地方遭受洪涝水淹,水稻受淹后其生长发育受到影响,“水害”伤根矛盾非常突出,加强当前早稻的肥水管理,是洪涝灾害后不可忽视的重要措施,应分轻重缓急做好以下几项工作。迅速排涝,缩短受淹时间。凡可采取人工措施排除内涝或积水,应迅速集中人力和物力进行抢排,尽量减少受淹时间。但应注意排除方式,不能一下子急于排干,开始应维持浅水层,然后逐渐排干。以避免因受涝后水稻根系活力
After the planting of early rice this year, the southern part of China has been losing heavy rains and heavy rains for many days. Many places have been flooded with flooding water. The growth and development of paddy rice have been affected after flooding. The contradiction between the “water damage” and the root causes is very prominent. Is an important measure that can not be ignored after floods and floods and should be given the following priorities in light of the following tasks. Quick drainage, shortening flooded time. Where any man-made measures can be taken to eliminate waterlogging or stagnant water, the manpower and material resources should be rapidly concentrated for robbing and draining so as to minimize the flooding time. However, we should pay attention to the way of exclusion. We can not rush to draining at once. We should start with the shallow water layer and drain it gradually. In order to avoid the root activity of rice after being flooded
