How to manage Water and Fertilizer in Rice after Flood
What problems should be paid attention to in washing rice seedlings? The paddy fields affected by the disaster should promptly remove stagnant water, straighten inverted seedlings, dredge ditches in time, and lower the groundwater level. If the loss of irrigation facilities is relatively heavy, emergency repairs should be organized in a timely manner. When the stagnant water in the paddy field retreats, the ditch should be opened to drain the soil water, and the water content in the field should be reduced as soon as possible, so that the floating mud formed by flooding can be gradually settled so as to promote the growth of new roots. For the fields that have been submerged for a long time, the water can be drained at one time in overcast and rainy weather, and should be drained gradually in case of hot sun and high temperature.

Pay attention to three precautions of rice after flood
From mid-late June to mid-late July, the southern region is often hit by torrential rain, and some areas are prone to floods. In case of flood and waterlogging disasters, in addition to carrying out routine remedial measures, attention should be paid to the prevention of the epidemic of bacterial diseases and the outbreak of migratory pests. Prevent the epidemic of bacterial brown stripe disease. With the flooding, the bacteria were able to spread and spread and infect through the wounds caused by Rain Water and rice plants during the flood. The resistance of flooded rice plants decreased, which was more conducive to the epidemic of the disease. There is a process from the flood to the epidemic of the disease, therefore, for the medium rice in the flood area,

Is the replanted rice damaged by quinclorac?
Q: 4 mu of direct seeding rice is in 3 leaves and 1 heart stage, few seedlings emerge after sowing, no seedlings are found in low-lying areas, the emergence rate is less than 50%, 7~7.5 kg are sown per mu, and not long ago, quinclorac "two kill" weeding is used. May I ask, if rice is replanted in this field where there is no seedling, will the replanted rice be damaged by quinclorac? A: Quinclorac is a selective herbicide for controlling barnyardgrass in rice fields. It is generally applied at the 2-leaf and 1-core stage of rice. It is easy to cause phytotoxicity when applied too early. Before seedling 1-leaf stage, especially seedling needle stage, apply two kinds of fertilizer according to conventional dosage.
