Preparation method of disease-resistant culture medium

The invention discloses a preparation method of a disease-resistant culture medium. The preparation method comprises the following steps: preparing a vinasse leavening, and mixing the vinasse leavening with chitosan, perlite, corn flour, sodium sulfite, turf, gypsum, aloe gel, nano silver particles, sodium dihydrogen phosphate and dipotassium phosphate. When being used for seedling cultivation, the disease-resistant culture medium prepared through the preparation method can prevent seedlings from being infected by germs and viruses, and can enhance the disease resistance of the seedlings at the same time. 本发明公开了种抗病型培养基的制备方法，其包括以下过程：酒糟发酵物的制备，酒糟发酵物与壳聚糖，珍珠岩，玉米粉，亚硫酸钠，草炭，石膏，芦荟胶，纳米银粒子，磷酸二氢钠，磷酸氢二钾的混合。本发明制得的抗病型培养基用于幼苗栽培时不仅可防止幼苗被细菌、病毒感染，同时可增强幼苗的抗病性。
