沸石是一种含碱金属和碱土金属离子的含水铝硅酸盐。沸石做肥料增效剂,主要是利用沸石中氧、硅、铝三种元素构成的独特三维空间结构的吸附、筛分、离子交换等功能。原苏联曾将沸石做肥料添加剂使小麦增产13.9％～28％,土豆增产20％,氮的气态损失从43％减少到 24％～28％。日本、保加利亚及我国云南、浙江、内蒙等地均有应用,但未见系统报道。我们从1991年到1994年连续3年进行了多点试验、示范及大面积推广,初步获得了沸石对培肥土壤、增加肥效、增产增收的显著效果,特别是沸石对提高肥料利用率效果尤为明显。
Zeolites are hydrous aluminosilicates containing alkali metal and alkaline earth metal ions. Zeolite fertilizer synergist, mainly the use of zeolite oxygen, silicon, aluminum three unique elements consisting of three-dimensional structure of the adsorption, screening, ion exchange and other functions. In the former Soviet Union, zeolite was used as a fertilizer additive to increase wheat yield by 13.9% -28%, potatoes by 20% and nitrogen loss from 43% to 24% -28%. Japan, Bulgaria and China Yunnan, Zhejiang, Inner Mongolia and other places have applications, but no systematic reports. From 1991 to 1994, we conducted a series of experiments, demonstrations and large-scale popularization for three consecutive years. The preliminary results showed that zeolite has a significant effect on fertilizing the soil, increasing fertilizer efficiency, and increasing yield and yield. In particular, the effect of zeolite on improving the fertilizer utilization rate is particularly remarkable obvious.
