Late rice cultivation in rice requires skillful application of fertilizer. The sowing time of the post-indica beans, from late July to mid-August, too early and too late will affect the growth of soybeans. The specific requirements are to hurry for planting within one week after the harvest. The amount of sowing depends on the size of the grain, the height of the plant, the number of branches, the soil fertility and the level of fertilization. Fine-grained seeds are sown 60 to 67.5 kilograms per hectare, medium-sized seeds are 75-90 kilograms, and large-grained species are 90-105 kilograms; seeding methods include small squid sowing and on-demand, and the line spacing is 30-36 cm, and the pond spacing is 6-8. Cm, 3 to 4 capsules per pond, ensuring 67.5-82.5 million seedlings per hectare. After sowing, the cut rice piles are used as coverings, and the cover is not tightly covered with some straw covering, so that the seeds are not exposed, and the buds are shaded and the soil temperature is maintained to facilitate seed germination and emergence. However, the coverage should not be too thick, so as to avoid the occurrence of uneven seedlings or the growth of high seedlings. In addition, the application of fertilizers has different effects on soybean yield. Immediately after emergence, urea is applied to 3-6 kg/mu per hectare plus 70 kg of potassium chloride (4-5 kg/mu) for seedling fertilizer, and nitrogen and potassium fertilizers are applied once again during the branching period. 3 dry grams / mu compound fertilizer for flower fertilizer, rooting outside the pod-spraying fertilizer, spring soybean autumn species should be in the "mainly pay attention to base fertilizer, early application of seedling fertilizer, skillful application of flower fertilizer, discretionary application of drum fertilizer", specific control per hectare application Pure nitrogen 99.5 kg, 216 kg of urea (1.6 kg per mu of pure nitrogen, 14.3 kg per mu of urea), P2O5157.5 kg, 1125 kg of calcium phosphate 1125 kg per mu, 10.5 kg per acre, 75 kg per acre of calcium phosphate , K2O9.75 kg, 2403.75 kg of potassium chloride, can get high yield.
