Bean vegetable efficient fertilization technology


Legumes including beans, kidney beans, lentils, peas and other legumes to obtain vegetable production of high quality, high yield, high efficiency, carefully grasp the saving and efficient fertilization technology to effectively reduce production costs is the key.

   1 . Defining the characteristics of fertilizer, and setting the fertilizer as needed. The straight roots of legumes are developed, and there are different shapes of nodule symbiosis. They have nitrogen fixation effect, which can fix nitrogen in air and soil for their own benefit. The requirements for soil nutrients are not very strict, but they also require higher fertilizer. Vegetables, especially for phosphorus and potassium, are in high demand. Production advocates the application of stable base fertilizer . Generally, according to the soil fertility condition, on the basis of 667 square meters (1 mu ) of high-quality decomposed organic fertilizer 2000 to 2500 kg, the special fertilizer for bean-based vegetables is 25 to 35 kg. However, care should be taken not to use unfertilized organic fertilizer as the base fertilizer, otherwise it will lead to rotten seeds, affecting yield and quality.

   2 . Grasp the key period of fertilizer demand and fertilize in stages. Focus on the application of seed fertilizer, bean vegetables begin flower bud differentiation soon after sowing, enter the development period, the application of seed fertilizer can ensure early development needs, generally apply 4 to 5 dry grams of three-element compound fertilizer per 667 square meters , pay attention to seed fertilizer separate. Nitrogen-fixing Rhizobium seedling weak, appropriate dressing can promote early seedling development, 667 per square meter can be applied beans special fertilizer 8-10 kg. Flowering pod period is the vegetative and reproductive growth booming period, a large amount of fertilizer needed, can be applied per 667 square meters of dry beans, 20 grams of specialty fertilizer, fertilizer for flowering to reduce flower and pod abscission, improving fertilizer stamina, to improve and strong action to prevent premature aging. The application method advocates the application of the side of the root ditch to reduce the loss and improve the fertilizer utilization rate.

   3 . Master the two principles of fertilization. Organic fertilizer, chemical fertilizer as auxiliary; to basal mainly to supplement dressing, foliar fertilization attention.
