提高肥料利用率研究初报──包裹型复肥及其应用

Preliminary Study on Raising the Utilization Ratio of Fertilizers -Coated Compound Fertilizer and its Application

鉴于国内外肥料利用率普遍较低的现实，提高肥料利用率的研究已引起人们的广泛关注．新型缓释性肥料－包裹型复合肥将提高肥料利用率的工作向前推进了一步．本文介绍了包裹型复肥的生产工艺、产品类型、肥效以及几种主要作物生长过程中对肥料需求的曲线．提出了为进一步提高肥料利用率，生产与作物生长相适宜的全含量肥料对包复肥的新要求．

In view of the common fact of low utilization ratio of fertilizers both at home and abroad,studies on raising the utilization ratio has attracted people's wide attention.A new type of slow release fertilizer-Coated Compound Fertilizer has pushed the study of raising the utilization ratio of fertilizers forward.The manufacture process,product specifications,fertility of Coated Compound Fertilizer and the nutrients absorption characteristics of several main crops during different growth stages are described,and the new demand on Coated Compound Fertilizer is in order to produce the complete nutrients content fertilizer adapted to plant growth and improve the utilization ratio of fertilizers is put forward.
