Summer soybeans produce high benefits
Base fertilizer: organic fertilizer is best to cover the bottom of arable land before sowing, the amount of farmhouse fertilizer 45000-60000 kg per hectare, or cake fertilizer 600-750 kg. While increasing farmyard manure, it is also necessary to use chemical fertilizers as the base fertilizer at a reasonable ratio, mainly phosphorus, supplemented by nitrogen fertilizers. Generally, 375-450 kg of phosphate fertilizer, 45-75 kg of urea or 300 kg of ammonium bicarbonate, or 375 kg of diammonium per hectare are applied per hectare. Potash (potassium chloride) 225 kg can also be applied per hectare. In addition, during periods of intense agricultural activities, it is not possible to apply basic fertilizer to soybeans in a timely manner, and the base fertilizer for the two crops can be applied to soybeans in the first crop of wheat crops in a planned manner to make the soybeans use residual fertilizer and obtain a good harvest. Farmers have high quality fertilizers and a good soil foundation. If the former crops are fertilized with too much fertilizer, they can be used less often. Otherwise, they should be applied more. Base fertilizer for soybeans can be flexibly controlled according to specific conditions. Fertilizer: Before sowing, 5 grams of ammonium molybdate, 10 grams of borax and 5 grams of zinc sulfate are weighed in every 5 kilograms of seeds, and then fully dissolved in 400-500 grams of warm water. Then, the fertilizer solution is sprayed on the seeds to make the fertilizer cloth as effective as possible. Full of seeds, sowing immediately after drying. Top dressing: The effect of phosphate fertilizer on the growth and development of soybean is more obvious than that of nitrogen fertilizer. The effect of phosphorus fertilizer yield increase is related to the available phosphorus content in soil. The available phosphorus in the soil is above 60 mg/kg, the effect of phosphorus application is small and unstable, and the effective phosphorus is less than 10 mg/kg, which significantly increases the yield. The application period was better in the branching period before flowering, that is, in mid-July. The effect of potash fertilizer production has obvious differences according to different soil conditions. In potassium-depleted soils, the potassium application of soybeans has a good effect on the growth and development of the leaves, extending the functional period of the leaves, increasing the accumulation of dry matter, and increasing the nitrogen-fixing capacity, and the yield increase is significant. Potash should be applied at the branching stage. The basal-fertilized plots were re-applied once in the first five days before the initial flowering of soybeans, and 75-112.5 kg of urea could be recovered per hectare, and 75-105 kg of potassium fertilizer was appropriately applied depending on the seedling condition. The topdressing method is suitable for furrowing. For the field where base fertilizer cannot be applied, fertilizer should be applied early in the seedling stage. Generally in mid-July, according to soil fertility, 75-150 kg of urea is applied per hectare, 225-300 kg of fertilizer is applied to fertilizer, or about 75 kg of urea per hectare, 150-225 kg of phosphoric acid diamine, and about 150 kg of potassium chloride. Foliar spray fertilizer: foliar spray fertilizer directly absorbed through the leaves, can play the same role as the roots of fertilization, and can reduce soil fixation and loss, faster than the root application, higher utilization. Soybean root dressing is generally 1-2 times, such as spraying 1st, from early flowers to full flowers is appropriate; spray 2 times, the first time in the early flowering period, the second in the final flowering period. Fertilizing methods include artificial knapsack sprayers, motorized mist sprayers, and aircraft spraying. Either way, it requires good atomization and even spraying. In case of rain, re-spray is required within 6 hours after spraying. Foliar spraying method can directly absorb the foliage and reduce soil fixation and loss. Fertilizers used for foliar spraying are quick-acting. The amount of fertilizer used for artificially spraying general hectares is: 2.25-3.00 kg of potassium dihydrogen phosphate, l5-22.5 kg of urea, 0.3-0.45 kg of ammonium molybdate, 1.125-1.500 kg of borax, and 750-1125 kg of water. These fertilizers can be sprayed separately or mixed. In order to treat diseases and pests, it can also be sprayed with pesticides.
