种植在江、河、湖边等地势低、排水条件差的水稻,极易受到洪水淹没。受淹水稻由于被水淹没部位、时间及补救措施不同,水稻生长和产量影响相差很大。因此,在强降雨的洪涝灾害面前,及时采取正确的清沟、排水、施肥等补救措施,对受淹水稻恢复生长,减轻灾害影响,减少经济损失效果显著。笔者根据多年的工作经验,现就受淹水稻的特点与补救措施介绍如下。1.受淹水稻后表现特点不同类型和不同生长期的水稻,其耐涝性不同。一般杂交稻耐涝性强于常规籼 Planted in the rivers, lakes and other low-lying, poor drainage conditions of rice, vulnerable to flooding. In flooded rice, due to the submerged parts, time and remedial measures, the effects of rice growth and yield vary greatly. Therefore, timely and correct remedial measures such as clearing gully, draining water and fertilizing before flood disaster with heavy rainfall are effective in restoring the affected flooded rice, reducing the impact of disasters and reducing economic losses. The author based on years of work experience, is now flooded rice characteristics and remedial measures are described below. 1. Characteristics of flooded rice after the performance of different types and different growth stages of rice, its waterlogging different. The waterlogging resistance of hybrid rice is better than conventional indica rice
