The application provides a fertilization method based on rice tillering dynamics and application thereof, and relates to the technical field of rice cultivation. According to the
fertilizer requirement law of rice and the soil
nutrient supply capacity, the application adopts a front control, middle promotion and rear supplement mode, guides fertilization through the growth and decline law of tillers, improves the ratio of ear grains to
fertilizer, and can fully meet the demand of rice for
nitrogen in the later growth period, thereby solving the technical problems in the prior art that the front promotion of
nitrogen fertilizer can promote a large number of tillers, but the number of ears does not increase, instead, the effective
tiller rate is reduced, the ear is smaller, and the maturity is reduced, and meanwhile, the application can cause the technical problems of lodging, increased pests and diseases and the like. The application achieves the technical effects of effectively improving the quality of rice
population, promoting large ear formation, improving the seed setting rate of rice and greatly increasing the yield of rice.
