目前我国肥料利用率低于国际平均水平,尤其是磷肥的利用率更低,平均在15％左右。这样不仅造成资源浪费,而且还使土壤变得越来越板结。 怎样把土壤当中被固定的磷活化释放出来?怎样提高磷肥的利用率?东北农业大学经过几年的研究,现研制出一个新产品——磷素活化剂。 一、该活化剂的作用和特点 1.提高肥料的利用率 经过试验证明,磷素活化剂一般能提高磷肥利用率10％左右。另外,它还可以把土壤中被固定的没有效的作物不能吸收利用的磷,变成作物可以吸收利用的有效磷。
At present, China’s fertilizer utilization rate is lower than the international average, especially the utilization of phosphate fertilizer is lower, averaging around 15%. This not only results in a waste of resources but also makes the soil more and more compacted. How to activate the fixed phosphorus in the soil is released? How to improve the utilization of phosphate fertilizer? Northeast Agricultural University after several years of research, is now developing a new product - phosphorus activator. First, the role and characteristics of the activator 1. To improve the utilization of fertilizers After tests showed that phosphorus activators can generally increase the utilization of phosphate fertilizer about 10%. In addition, it converts phosphorus that can not be absorbed by inefficient crops that are immobilized in the soil into usable phosphorus that the crop can absorb.
