Bean vegetable fertilization technology
Beans and vegetables refer to the annual or biennial herb of Leguminosae, mainly refers to the legumes of nine genera such as kidney beans, cowpeas, peas, edamame, broad beans, lentils, kidney beans, kidney beans, and quadrangular beans. Pods and fresh beans are served. The straight roots of legumes are developed, and there are different shapes of nodule symbiosis. The ratio of nitrogen, phosphorus and potassium is 1:1:1. At the same time, trace elements such as molybdenum, boron, zinc and copper are needed. Beans and vegetables are fertilized to increase production.
1. Fertilizer base fertilizer The base fertilizer of legume vegetables should use long-acting compost compost, and it is not advisable to use too much nitrogen fertilizer as seed fertilizer to prevent rotten seeds. Generally, the organic fertilizer is 1000-1500 kg, the bio-organic fertilizer is 60-80 kg, or the urea is 15 kg, the potassium chloride is 15-20 kg or the plant ash is 100 kg, and the superphosphate is 15-25 kg. Generally, the depth of application is 8-10 cm, and the seed is 6-8 cm.
2, root topdressing Beans and vegetables need to be medium-fat, according to the principle of "basic fertilizer, supplemented by topdressing". When the seedlings are thin, the nitrogen fertilizer is applied, and the concentration is appropriately increased as the plant grows. Generally, 20 kg of compound fertilizer is applied per mu.
3. Top dressing outside the roots The flowering stage and the final flowering stage are sprayed with urea, ammonium sulfate, and superphosphate leaching solution. Generally, the urea is 1-2 kg of urea, 1-2 kg of potassium dihydrogen phosphate, and 40-50 kg of water.
4, inoculation of Rhizobium Artificial inoculation of Rhizobium before sowing, can promote early formation, more formation of nodules. Generally, the legume rhizobium agent is purchased from the market and applied according to the instructions for use. If there is no commercial rhizobium agent, you can take it locally. For example, select the large and numerous nodules of the roots of the kidney beans, cut them into bags, wash them with water in the dark, in the dark room. Dry under °C. After drying, mash it into a powder and store it in a cool dry place for 1 year. Before sowing, after the selected seeds are disinfected, spray a small amount of water to wet the surface of the seeds, and spray 50 g of the rhizobial agent to wet, and finally mix the two to sow.
