1. Appropriate application of nitrogen fertilizer to promote the growth of rice tillers and vegetative bodies.
2, to strengthen the management of the water layer, that is not drying the field, it should not cut off water.
3, to strengthen booting, heading and post-management. For plots whose earings are about to heading, they should not dry their fields, but must intensify their time to rehydrate, maintain a certain water layer, and avoid empty grains after the spikelet differentiation due to water shortage; timely application of panicle fertilizer to promote early birth of the tiller panicles The main role of tiller panicles in yield composition was fully exerted, and the yield loss due to early panicles was restored to the greatest extent; during heading, 920 leaf sprays could be applied to promote full panicles when the panicle panicles were extracted by about 5%. In the booting stage and heading stage, potassium dihydrogen phosphate was sprayed on the leaves and sprayed once after 5-7 days to prolong the photosynthesis period of functional leaves, increase the seed setting rate, and increase the yield and reduce the loss.
