Preparation method of soilless grafted-seedling culture medium

The invention discloses a preparation method of a soilless grafted-seedling culture medium. The preparation method includes: preparing the fermentation product of distillers' grains, mixing the fermentation product with chitosan, perlite, corn flour, sodium sulfite, turf, gypsum, aloe vera gel, nano-silver particles, sodium dihydrogen phosphate and dipotassium hydrogen phosphate, and evenly continuously adding calcium carbonate and ammonium chloride during the mixing. The soilless grafted-seedling culture medium prepared by the method has the advantages that when the soilless grafted-seedlingculture medium is applied to grafted-seedling culture, grafted seedlings can be prevented from being infected by bacteria and viruses, and the disease resistance of the grafted seedlings can be enhanced at the same time. 本发明公开了种无土嫁接苗培养基的制备方法，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，在混合中均匀、持续地添加碳酸钙及氯化铵。本发明制得的无土嫁接苗培养基用于嫁接苗栽培时不仅可防止嫁接苗被细菌、病毒感染，同时可增强嫁接苗的抗病性。
