Fertilizer characteristics During the growth period of the bean, the potassium and nitrogen fertilizers were absorbed, followed by the phosphate fertilizer. For every 1000 kg of beans, the nitrogen consumption was 3.37 kg, the phosphorus was 2.26 kg, and the potassium was 5.93 kg. In addition, proper application of trace elements such as boron and molybdenum can also promote the growth and development of plants. The fertilization amount per mu of the bean is 2500-3000 kg (or commercial organic fertilizer 350-400 kg), nitrogen fertilizer (N) 8-10 kg, phosphate fertilizer (P2O5) 5-6 kg, potassium fertilizer (K2O) 9～ 11 kg. Organic fertilizer is used as base fertilizer, nitrogen and potassium fertilizer are divided into base fertilizer and twice top dressing, and phosphate fertilizer is used as base fertilizer. Fertilizer and farmyard manure (or commercial organic fertilizer) are mixed. Generally medium fertility fields, the target output per acre is 1500-2000 kg, and the base application and topdressing fertilizer can be carried out according to the following scheme. The low fertility field is slightly increased on this basis, and the high fertility field is appropriately reduced.
The base fertilizer is generally medium fertile field, the target output per mu is 1500-2000 kg, and the farmer's fertilizer can be applied 2500-3000 kg (or commercial organic fertilizer 350-400 kg), urea 3~4 kg, diammonium phosphate 11-13 kg, potassium sulfate. 6 to 8 kg.
Topdressing In the vine-growing period, 6-9 kg of urea per acre, 4-6 kg of potassium sulfate; 5-7 kg of urea per acre during flowering and pod-forming period, and 4-6 kg of potassium sulfate.
Top dressing at the roots of the pods is sprayed with 0.3% to 0.4% potassium dihydrogen phosphate or trace element fertilizers for 3 to 4 times, once every 7 to 10 days, and the facility can be supplemented with carbon dioxide gas fertilizer.
