Recently, heavy rains have occurred in most parts of the country, causing floods in some areas. From June 27 to 29, Gushi County suffered heavy rainfall continuously, with an average rainfall of 226 mm. Heavy rainfall caused the area of ​​350,000 mu of rice in the county to be flooded to varying degrees. Although the whole county worked hard to resist external floods and rush to discharge guilt, some areas of rice were seriously damaged by immersion in the pupa. In view of how to do well in the field management of different growth stages of rice after the disaster, Li Jingrong, a senior agronomist in Gushi County, recently pointed out several major management points in an interview. One must clear the ditch drainage. By the floods soaked rice fields in time to remove water, righting lodging seedlings; time to clear the "Three ditch" Wada drainage channels outside the Gully interlinked, lower the water table. Water system is not perfect, we must do a good job in the field ditch system supporting timely, assault by digging the drain, drains, drainage as soon as possible, in order to ensure good root system of rice transparent environment, promote root growth and recovery as soon as possible. For the fields with long flooding time, the rainy weather can drain the water at one time. If it is hot in the hot weather, it should be gradually drained. Let the upper part of the rice plant be exposed to the water surface, dehydrate the gas at night, and shed the night to facilitate the growth of rice. When drainage, should also pay attention to remove floating debris, lodging and hand-by-line to lift up the rice plants. Care should be taken when cultivating rice plants to avoid roots and wounds, and then spray and wash the debris on the rice plants to restore the physiological functions such as photosynthetic respiration. Paddy water back, the water is still saturated field, should ditch drainage, soil water infiltration into the field ditch discharge, reduce the water content of the field as soon as possible, so that the formation of floating sludge flooded gradually pragmatic and to promote new root Growth. Second, fertilize and supplement. After the disaster, we should carefully observe the rice growth process, growth, leaf color, etc., and carry out corresponding irrigation, fertilization, plant protection and other regulation and management. For the field of rice early growth, and the leaf color is lighter, the blue-yellow field and the three types of seedlings appear. It is necessary to timely apply the strong grain fertilizer. Generally, the application of urea is 2 to 2.5 kg, and the potassium chloride is 2.5 to 3 kg. For the field that is about to enter the heading and flowering, it is necessary to carry out the top dressing. Foliar spraying with 0.5% urea + 0.2% potassium dihydrogen phosphate solution + 0.1% boric acid to achieve spike-preserving and panicle-increasing; for high-yield fields with lush growth and strong green color, it should not be fertilized, because the seedlings are over-absorbed, Causes the organization to be soft, love green, susceptible to pests and diseases, easy to fall, and will also reduce production. However, it is necessary to drain the drained water in time, implement humid irrigation, reduce the humidity in the field, and improve rice stress resistance and rice yield. Finally, pest control. After the rice is flooded, the leaves are injured, the disease resistance of the plants is reduced, and the temperature and humidity in the field are suitable for the growth and spread of the pests, which may cause the occurrence of pests such as sheath blight, rice blast, rice planthopper, etc., and special attention should be paid to prevention and control.
