Fertilization Technology for Cereal and Vegetable Broad Bean

According to the analysis, for every 100 kilograms of grain and its corresponding organisms, nitrogen is required to be 6.7 to 7.8 kilograms, phosphorus is 2 to 3.4 kilograms, potassium is 5 to 8.8 kilograms, calcium is 3.9 kilograms, and various amounts of trace elements are required.

Before sowing, 30,000 kg of fermented organic fertilizer per hectare. At the seedling stage, 10,000 kg of manure per hectare, or 75-100 kg of urea, or 75-150 kg of compound fertilizer, make the seedlings strong and promote early branching and multiple branches. At the beginning of flowering, 75-100 kg of urea and potassium chloride per hectare are applied to promote the growth of stems and leaves, and the development of buds and flowers. At the beginning of the pod-forming period, 150-225 kg of compound fertilizer per hectare is applied to increase the pod-forming rate. During the growth period, be careful not to apply nitrogen fertilizer to avoid causing the plant to grow. Practice has proved that the application of trace element fertilizers such as 0.2% to 0.3% potassium dihydrogen phosphate solution and ammonium molybdate 2 to 3 times outside the rooting stage has obvious effects on yield increase.
