磷是农作物生长发育必不可少的重要元素,在缺磷的土壤中适量施用磷肥,对提高农作物的产量和品质有良好作用。但不少农民朋友误认为磷肥施用越多越好,其实过量施用磷肥不仅无益,而且危害很大。一是消耗作物贮存的糖分和能量。施用磷肥过量,会使作物从土壤中吸收过多的磷素营养,过多的磷素营养会促使作物呼吸作用过于旺盛,消耗的干物质大于积累的干物质,造成繁殖器官提前发育,引起作物过早成熟,籽粒小,
Phosphorus is an indispensable element of crop growth and development. Appropriate application of phosphate fertilizer in phosphorus-deficient soils can improve the yield and quality of crops. However, many farmers and friends mistakenly believe that the better the application of phosphate fertilizer, in fact, excessive use of phosphate fertilizer is not only useless, but also a great harm. The first is the consumption of crop storage sugar and energy. Excessive use of phosphate fertilizer can cause crops to absorb too much phosphorus nutrition from the soil. Too much phosphorus nutrition can cause the respiration of plants to be over-exuberant, which consumes more dry matter than the accumulated dry matter, resulting in early development of reproductive organs and causing crops Premature mature, small grains,
