A MANNFACFURING METHOD OF PLANT TONIC INCLNDING NANO-IRON ION OF AN AQUEOUS SOLUTION

摘要

A method for preparing a plant tonic and a method for preparing a plant nutritive ceramics powder are provided to recover the acidified soil, prevent damages by blight and harmful insects and promote growth of agricultural products without fertilizers and agrichemicals. The method comprises the steps of: (a) mixing 15 wt.% of a mixture of Au and Ce in the ratio of 20:80, 15 wt.% of Cu catalyst, 15 wt.% of Mn catalyst, 20 wt.% of Pt catalyst, 15 wt.% of amine based catalyst, and 20 wt.% of Ag catalyst to obtain nano-iron aqueous solution; (b) synthesizing Fe, Cu, Mn, K, P, S, Zn, Ca, Mg and the like to obtain synthetic iron ion aqueous solution; (c) after mixing 25 wt.% of kaolin containing 38 wt.% of Al2O3, 10 wt.% of bentonite, and 15 wt.% of transition metal oxide such as Cr2O3, MnO, Fe2O3, NiO, CuO, and CoO with 15 wt.% of acrylic binder and molding it, drying it at room temperature and further drying it in a kiln at a temperature of 1,300-1,500 deg.C and then cold-crushing it to obtain porous ceramics powder.
