对河南省肖河沸石矿进行了系统的物性测定和化学分析以及对其在肥料生产中的应用进行了实验研究。结果表明 :该沸石矿不仅含有对植物生长有用的K2 O、MgO以及Zn ,Cu ,Mn ,Fe等多种微量元素 ,而且具有较强的吸附性和阳离子代换能力 ,对改良土壤和提高肥效均具有显著影响。肥效试验证明 ,沸石复混肥与对照相比可提高产量4 5.7% ,比添加膨润土的情况增产 7.6%。
The physical property determination and chemical analysis of Xiaohe zeolite mine in Henan Province were carried out and its application in fertilizer production was studied experimentally. The results show that the zeolite ore contains not only K2O, MgO, Zn, Cu, Mn, Fe and other trace elements which are useful for plant growth, but also has strong adsorption and cation substitution ability, which can greatly improve soil fertility and improve fertilizer efficiency All have significant effects. Fertilizer efficiency tests showed that the zeolite compound fertilizer can increase the yield by 47.7% compared with the control and increase the yield by 7.6% compared with the case of adding bentonite.
