Selenium-rich multi-element functional ceramsite and preparation method thereof
The invention relates to selenium-rich multi-element functional ceramsite and a preparation method thereof, and belongs to the technical field of soilless culture materials. The method comprises the following steps: grinding and sieving a functional material I, granulating an undersize dry powder material in a granulator, adding water during granulation to obtain raw ceramsite, drying the raw ceramsite, and roasting the raw ceramsite. The ceramsite is prepared with the functional material I as a raw material; wherein high-temperature roasting is needed in the preparation process to change thewater solubility of each element in the functional material I, , such that the finally prepared ceramsite can release the nutrients required by plants, and the rare earth elements can release the farinfrared and the negative oxygen ions after the high temperature treatment so as to easily achieve the photosynthesis of the plants, improve the soil structure, inhibit the bacterial growth, and provide the good growth environment for the plants. The preparation method of the ceramsite is simple, low in cost and suitable for expanded production.
本发明涉及一种富硒多元素、功能性陶粒及其制备方法，属于无土栽培材料技术领域。该方法如下：将功能材料I研磨、过筛，取筛下干粉物料置于造粒机中造粒，造粒期间加水，获得生陶粒，将所述生陶粒烘干后焙烧，即可。该陶粒以功能材料I为原料，由于制备过程中需经高温焙烧，改变功能材料I中各元素的水水溶性，使最终制得的陶粒能够释放出植物所需的营养元素，并且稀土元素经高温处理后，能够释放出远红外和负氧离子，从而有利于植物的光合作用，同时还能改善土壤结构，抑制细菌生长，为植物提供更好的生长环境。该陶粒制备方法简单，且成本低，适合扩大化生产。
