一、磷素对作物的作用作物体内许多重要物质如核蛋白、核酸、卵磷脂、植素等都含有磷(P)。因此,施用磷肥能促进作物细胞及时分裂,发根、分蘖加快,在早稻秧田施用少量磷吧,能使秧苗健壮,减少烂秧。磷又能加强作物体内糖分、淀粉,脂肪的合成与运转。磷肥施用于豆科,油料,糖料和薯类等作物,能提高这些作物的产量和品质。磷素又能够促进作物体内呼吸与代谢作用旺盛,根系吸肥能力增强,对外界环境的适应性提高。因此,作物在磷的影响下,根系发达并伸入较深的湿润土层中吸取水分,又因磷能提高细胞中原生质胶粒束缚水的能力,从而使作物的抗旱能力增强:
First, the role of phosphorus on crops Many important substances in the body of the body such as nuclear protein, nucleic acid, lecithin, and other plants contain phosphorus (P). Therefore, the use of phosphate fertilizer can promote the timely division of crop cells, hair roots, tillers to speed up, in the early rice seedling application of a small amount of phosphorus bar, seedling can make robust and reduce rotten seedlings. Phosphorus can also strengthen the body of sugar, starch, fat synthesis and operation. Phosphate fertilizers applied to crops such as legumes, oilseeds, sugars and potatoes can increase the yield and quality of these crops. Phosphorus can also promote the respiration and metabolism of crops in vivo, root absorption capacity increased, the adaptability to the external environment increased. Therefore, the crop under the influence of phosphorus, the root developed and extended into the deeper moist soil to absorb water, and because phosphorus can increase the capacity of protoplasmic particles in the cell binding water, so that the ability of crops to enhance drought resistance:
