How to fertilize rice in the later stage?

How to fertilize rice in the later stage? Please introduce the method of applying fertilizer skillfully in the later stage of rice cultivation. During the sowing period of post-rice beans, from late July to early and mid-August, too early and too late will affect the growth of soybean. It is specifically required to sow seeds within a week after rice harvest. The sowing rate depends on the grain size, plant height, number of branches, soil fertility and fertilization level. Fine seed sowing 60,67.5kg per hectare, medium seed 75kg and large seed 90kg 105kg. Sowing methods include small soil moisture evenly sowing and on-demand sowing, with row spacing of 30,36cm, pond spacing of 6cm and 4 seeds per pond, ensuring 67.5 ~ 825000 seedlings per hectare. After sowing, the cut rice pile is used as the mulch, and some straw is added to the loose cover, so that the seeds are not exposed, which plays the role of shading during the budding stage and maintaining the soil temperature, so as to facilitate the germination and emergence of the seeds. But the cover should not be too thick, so as not to cause uneven emergence or grow into tall seedlings and affect the yield. In addition, the application of fertilizer can increase the yield of soybean in varying degrees. Immediately after emergence, urea 3kg / mu plus potassium chloride 70kg / mu is used as seedling fertilizer, nitrogen and potash fertilizer is applied again at branching stage, and fertilizer is applied at the first flowering stage. Generally, 2-3g / mu compound fertilizer is used as flower fertilizer, and fertilizer is sprayed outside the root at podding stage. Spring soybean autumn seeds should be under the principle of "paying attention to base fertilizer, early application of seedling fertilizer, skillful application of flower fertilizer, and application of bulging fertilizer as appropriate". Apply 99.5kg pure nitrogen per hectare, 216kg urea (6.6kg / mu, 14.3kg / mu), P2O5157.5 kg, 1125 kg 2O5kg / mu, 75kg / mu calcium superphosphate, K2O9.75 kg, 243.75 kg potassium chloride.
