Fertilizer in bean vegetables, although nodules, nitrogen fixation is weak. In the undeveloped rhizobia, it is necessary to use the available nutrients in the base fertilizer to promote plant growth and development. If unfermented chicken manure or other organic fertilizers are applied, the reducing gas in the soil will increase, the oxygen will decrease, and the rotten species and premature root ageing will occur, which will have a great impact on the yield. Therefore, if the base fertilizer is to be chosen to be completely decomposed organic fertilizer, it is not appropriate to use too much nitrogen fertilizer. Top dressing is generally conducted 20 to 25 days after sowing. When the flower bud differentiation of legumes begins, if no base fertilizer is applied and the symptoms of fertilizer deficiency are shown, top dressing and top dressing shall be performed in time. Sulfuric acid may also be added to thin stools. Potassium. Early application of topdressing, but the application of excessive nitrogen fertilizer at the seedling stage will make the bean leggy. Therefore, the amount of topdressing should be based on the growth of the plant. In addition, spraying new high-fat membrane and fruit-benefiting can increase the positive energy of the plant's ecological growth, broaden the route of plant conduits, increase the water absorption capacity of plants, and increase fruit yield and quality.
