粉煤灰硅钙肥是火力电厂在粉状燃煤中加石灰石燃烧后,经水淬磨细而制成。它的主要有效成分是硅和钙,所以称为硅钙肥。其肥效、增产机理及有效施用条件等问题,是国家环保部门、肥料生产和使用单位以及农业科技人员十分关心的问题。以往我们曾就其中某些方面作过简单报导,本文主要对硅钙肥的增产原因及有效施用条件作一些探讨。
Fly ash calcium silicate fertilizer is a thermal power plant in the pulverized coal plus limestone combustion, made by the fine water quenching. Its main active ingredient is silicon and calcium, so called calcium silicate fertilizer. Its fertilizer efficiency, production mechanism and effective application of such issues as the state environmental protection departments, fertilizer production and use of units and agricultural science and technology personnel are very concerned about the issue. In the past we have made some simple reports on some of these aspects, this paper mainly on the production of calcium silicate reasons for the increase and effective application conditions for some discussion.
