Soybean flower fertilizer can not be less
In order to obtain high yield, in order to obtain high yield, in addition to the application of urea 3 to 5 kg and 7 to 15 kg of superphosphate in the seedling stage (the first compound leaves are unfolded), fertilization should be applied during the growth period to increase the yield. 1. Skillful application of flower fertilizer. The flowering and pod-forming stage of soybean is the peak period of fertilizer requirement in the whole life. In the flowering period, the appropriate amount of nitrogen fertilizer can be applied, and the urea is generally 5-8 kg/mu. Open the hole 5 to 7 cm from the root of the soybean, and cover the soil in time after application. If the soil fertility is high, the base fertilizer or seed fertilizer is sufficient, and the plant grows vigorously and vigorously, it is necessary to apply less or no top dressing to avoid causing lengthening, lodging or flower pods to fall off. In addition, when the phosphate fertilizer is insufficient, it is better to chase the calcium phosphate 7 to 19 kg/mu. 2. Make up the grain fertilizer. After the soybean enters the drum stage, the root activity gradually declines and the ability to absorb fertilizer is weakened. At this time, the foliar fertilizer supplementation measures can compensate for the nutrient deficiency in the pod-forming period, reduce the flowering and falling pods, increase the yield, and improve the quality; 30% of superphosphate 50-70 kg, if there is a phenomenon of de-pod, it should also add 0.5 kg of urea to prevent premature aging. 3. Spray micro-fertilizer. When soybean is deficient in magnesium, the older leaves appear grayish green, yellow spots appear between the veins, and 0.5% magnesium sulfate solution is sprayed at this time; when manganese is absent, the rest of the new leaves except the veins are yellow, which can be sprayed 0.5 in time. % of manganese sulfate solution; when the soybean is deficient in molybdenum, the young leaves are yellow-green, the chlorosis between the veins is enlarged and swollen, and the foliar spray is applied with 0.5% ammonium molybdate solution.
