摘要
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 properties determination and chemical analysis on the zeolite of Henan Xiaohe is introduced and the application of zeolite in fertilizer production is also experimented.The results indicate that this kind of zeolite contains K 2O,MgO and Fe,Mn,Cu,Zn etc.,which are benefit for plant growth,and Xiaohe zeolite has good effect on improving soil properties and fertilizer effect.Fertilizer effect experiment proves that zeolite containing compound fertilizer can raise the crops yield greatly,which is 45.6% higher than that of control,and 7.6% higher than that of bentonite containing compound fertilizer.
