一、需肥特点1、营养元素对花生的作用①氮:能促进花生枝多株壮,多开花,多结果。若氮素缺乏,则植株瘦小,分枝少,开花结果少,产量降低。但氮素过多,也会引起植株徒长倒伏,降低产量和品质。②磷:能促进花生侧枝发育、花芽分化和根系的发育,对根瘤发育和增强根瘤菌的固氮能力
First, fertilizer characteristics 1, the role of nutrients on the role of peanuts ① Nitrogen: can promote peanut branches and more strong, more flowering, and more results. If the nitrogen deficiency, the plant is thin, less branches, less flowering, yield reduction. However, too much nitrogen can also cause the plants to lean and reduce output and quality. ② Phosphorus: can promote peanut colony development, flower bud differentiation and root development, the development of nodules and enhance nitrogen fixation ability of rhizobia
