控释肥料的研究及其进展

综述了控释肥料的发展历程，对研制控释肥料的三大环节进行重点论述，物理阻隔法、合成难溶性肥料和添加生物抑制剂(或促进剂)改良常规肥料是主要的控释方法；涉及控释材料和生产工艺的主要是物理阻隔法，其材料范围正在迅速扩展，其生产工艺发展的主流是对现有工艺的改造。对控释肥料养分释放的测定方法、释放机理和及其影响因素作了简要阐述，并指出研究中存在的问题和最新进展。

Study and Review on the Controlled Release Fertilizers

The article briefly formulizes the lodgment and the development process on the controlled release fertilizers, and emphasizes to discuss on three parts of the manufacture of the controlled release fertilizers. It points out that the physical obstruct method, the synthesis of non soluble fertilizer and the addition of biological catastaltica(or accelerant) improvement routine fertilizer are main controlled release method; Relating to the controlled release materials and the product process is mainly the physical obstruct method, and its material range is rapidly expanding, and the main steam of its product process development is the modification of existing crafts. It briefly formulizes the measuring method, the release principle and the effect factors on the nutrient release of CRFs, and points out the existing problems and the newest development.
