The invention belongs to the technical field of succulent planting, and particularly relates to a preparation method of an anti-withering anti-
disease succulent nutritional solution. The preparation method specifically comprises the following steps: (1) weighing raw materials: (2) stir-frying green beans and glutinous rice, taking out the stir-fried green beans and glutinous rice, 
grinding into 
powder, mixing and uniformly stirring with water which is half of the weight, heating with 
slow fire, fermenting, taking out to obtain a fermented bean-rice solution; (3) smashing 
soybean meal, stir-frying, taking out, uniformly mixing and stirring with smashed fresh cockscomb flowers, 
processing with steam, taking out, uniformly mixing and stirring with the water which is half of the weight, cooling to the 
room temperature, fermenting to obtain a fermented 
soybean meal solution; and (4) uniformly mixing and stirring the fermented 
soybean meal solution and the fermented bean-rice solution and fermented potato juice, fermenting, taking out, extruding to collect juice, adding 
citric acid chelating 
magnesium, 
borax, 
houttuynia polysaccharides, 
isatis root 
polysaccharide and 
dandelion polysaccharide, stirring until dissolving to obtain the anti-withering anti-
disease succulent nutritional solution. By adopting the anti-withering anti-
disease succulent nutritional solution, the disease rate of the pachyphytum can be effectively reduced, the ground 
fresh weight of the parchyphytum can be increased, and the vigorous and strong growth of the parchyphytum can be promoted.
