饼肥中含氮、磷较多,是良好的氮磷肥料。其施用中的主要失误有: 一、腐熟后施用。饼肥虽属有机肥料,但其碳氮比(C/N)较小,施入土中分解速度较快,是速效性的有机肥料。因此可直接施用。如用河水、人尿浸泡腐熟后施用,虽然肥效快,但可造成10％的氮素损失,22.5％的有机质损失,弊大于利。 Cake fertilizer containing nitrogen, phosphorus more, is a good nitrogen and phosphorus fertilizer. The main mistakes in its application are: First, the application after maturity. Although cake fertilizer is an organic fertilizer, its carbon / nitrogen ratio (C / N) is relatively small, and its decomposition rate is faster when it is applied to soil. It is a quick-acting organic fertilizer. So can be applied directly. Such as the use of water, urine soaked maturity after the application, although the fertilizer fast, but can cause 10% of nitrogen losses, 22.5% loss of organic matter, more harm than good.
