Remedial measures for waterlogged crops Rice
Rice has a strong tolerance to waterlogging, with no top for about 3 days, and there are still about 80% of the surviving rice seedlings, as long as the management is strengthened; if the rice seedlings are not topped for 4-7 days, 50%-80% of the survived rice seedlings should be homogenized and replenished in time to ensure a sufficient population; if there are only about 30% of the surviving rice seedlings without the top for more than 7 days, replanting or replanting other crops should be considered. It is necessary to take measures in accordance with local conditions, give classified guidance, and conscientiously do a good job in the post-disaster management of rice.
