摘  要:
控释肥已成为国内外肥料研究的热点 ,但是评价控释肥养分释放特性的方法研究相对滞后 ,至今没有较为完善的方法和统一的测试标准。本文综述了包膜控释肥养分释放特性的现有评价方法 :水中 (或溶液 )溶出率法、土壤溶出率法、扩散率法、渗透率法、电超滤法和同位素示踪法等 ;评述了各种方法的优缺点及改进途径 ;并展望了今后评价方法的研究方向

摘  要:
Controlled release fertilizers (CRFs) have become a hotspot in fertilizer research in both domestic and abroad, but the researches in evaluation methods for nutrient release characteristic of CRFs are relatively backward. Up to now, there has not been perfect method and unified testing standard. This paper reviewed the present evaluation methods: water (or solution) dissolution rate method, soil dissolution rate method, infiltrate method, permeability method, isotopic tracer method and electroultrafiltration method , analyzing the merit, the shortcoming and the improving way of them and prospecting the direction of the evaluation methods in the future.
