据中国科学院南京土壤研究所汇总全国782个田间试验的资料,氮肥在我国的当季利用率平均为33.3％,比发达国家要低10～15个百分点;磷肥的当季利用率只有10％～15％,钾肥的当季利用率为35％～50％。因此,提高我国化肥利用率,减少浪费,有很大潜力可挖。 那么,如何提高化肥利用率,减少资源浪费,专家提出以下建议。1 加强宏观调控,制定提高化肥利用率的措施。
According to the data from 782 field trials conducted by the Nanjing Institute of Soil Science, Chinese Academy of Sciences, the average utilization rate of nitrogen fertilizer in our country is 33.3% on average, which is 10-15% lower than that in developed countries; the seasonal utilization rate of phosphate fertilizer is only 10% 15%, potassium seasonal utilization of 35% to 50%. Therefore, to improve China’s fertilizer utilization, reduce waste, there is great potential to dig. So, how to improve fertilizer utilization, reduce waste of resources, the experts made the following recommendations. 1 Strengthen macro-control and formulate measures to increase the utilization rate of chemical fertilizers.
