New key points of fertilization management for legume vegetables

Legume vegetables like fertilizer, although there are root nodules, but the effect of nitrogen fixation is very weak. In the undeveloped seedling stage of rhizobium, it is necessary to use the available nutrients in base fertilizer to promote plant growth and development. If the application of immature chicken manure or other organic fertilizer will lead to the increase of soil reducing gas, the decrease of oxygen, the premature aging of rotting seeds and roots, which will have a great impact on the yield. Therefore, base fertilizer should choose completely mature organic fertilizer, and should not use too much nitrogen fertilizer.

Topdressing is generally carried out 20-25 days after sowing. When legume vegetables begin flower bud differentiation, if there is no sufficient basal fertilizer, showing the symptoms of lack of fertilizer, topdressing should be carried out in time to apply dilute human and animal feces, and potassium sulfate can also be added to dilute manure. Topdressing should be carried out as early as possible, but applying too much nitrogen fertilizer at the seedling stage will make legumes grow too much. Therefore, the amount of topdressing should be determined according to plant growth. And spraying new high lipid film + vegetable fruit Zhuangtiling at podding stage can activate plant ecological growth positive energy, broaden plant vessel path, enhance plant water absorption and fertilizer absorption, and improve fruit yield and quality.
