合理施用磷肥能使农作物增产。过量施用,有人认为会无益地提高成本,但不会减产。实际上过多地施用磷肥,作物会出现“早衰症”和“足磷发僵症”,倒使农作物减产。如何因地制宜地合理施用磷肥是当前农业生产中的一个重要课题。施磷过多的弊害(1)磷能促进作物的呼吸作用,包括有氧呼吸及无氧呼吸(发酵)。在作物呼吸前,先要有磷的参与进行磷酸化作用,然后经过一连串酶的作用,形成各种有机酸,再经脱 Rational application of phosphate fertilizer can increase crop yield. Excessive application, some people think it will be beneficial to raise costs, but will not cut. In fact, excessive application of phosphate fertilizer will lead to “premature senility” and “stiff-footed Phosphorus” crops, which in turn will lead to a decline in crop yields. How to rationally apply phosphate fertilizer according to local conditions is an important issue in agricultural production. Excessive phosphorus harm (1) phosphorus can promote the respiration of crops, including aerobic and anaerobic respiration (fermentation). Phosphorus is involved in phosphorylation prior to crop respiration, and then through a series of enzymes that form a variety of organic acids,
