沸石是一种由火山熔岩水解变质而成的天然矿物,具有很大的比表面积和离子交换容量。它与容易挥发的碳酸氢铵以适宜比例混和,既可减少氨的挥发损失,又能改善碳酸氢铵易结块的物理性状。为探讨沸石碳酸氢铵的供肥特性、肥料的增产效应,以及施用技术,我们于1989～1990年以之与碳酸氢铵作了对比试验。现将试验结果报道如下。
Zeolite is a natural mineral hydrolyzed by volcanic lava, with a large specific surface area and ion exchange capacity. It is easy to volatile ammonium bicarbonate mixed with the right ratio, both to reduce the loss of ammonia volatility, but also improve the ammonium bicarbonate easy caking physical properties. In order to explore the characteristics of fertilizers for zeolite ammonium bicarbonate, the stimulation effect of fertilizers and the application techniques, we compared with ammonium bicarbonate from 1989 to 1990. The test results are reported below.
