肥料二次加工新技术的研究进展概述

Summary of Progress in Research of New Technology for Secondary Processing of Fertilizers

概述了肥料二次加工的必要性,详述了利用农业、工业、畜牧业等的废弃资源作为肥料二次加工的原料来源,不仅可克服施肥中存在的问题,而且可"变废为宝"保护环境。指出了肥料二次加工中应注意的问题,即有机与无机相结合,大量元素与中、微量元素相结合,速效与缓效相结合,农药与肥料相结合,营养元素的配置上注重土壤养分与不同农作物的养分需求相结合。今后肥料二次加工应向高效化、液体化、缓效化、复合化及复混化、功能化、生态环保化发展,只有重视科技创新,才能从根本上提升肥料的竞争力。

The necessity for secondary processing of fertilizers is summarized, and details are given of secondary processing of fertilizers based on rejected materials from agriculture, industry and livestock husbandry, thereby not only overcoming difficulties in fertilizer application but also recycling waste materials so as to protect the environment. Points of attention are indicated in secondary processing, viz., the combination of organic and mineral fertilizers, that of macro, secondary and micronutrients, that of quick- and slow-acting nutrients, that of pesticides and fertilizers, and in the arrangement of nutrients with Stress on the combination of soil nutrients and nutrient demand of different crops. In future secondary processing should develop in the direction of high efficiency, liquid fertilizers, slow release, compound or mixed fertilizers, functionalization, ecological effect and environmental protection, and only by emphasizing on scientific and technological innovation can the fertilizer competitive power be fundamentally promoted.
