Organic nutritional drought-resistance agent preparation and preparation method thereof

The invention relates to a crop growth regulating preparation which belongs to the technical field of crop chemical drought resistance and particularly provides an organic nutritional drought-resistance agent and a preparation method thereof. The organic nutritional drought-resistance agent is used for improving the drought resistance in crops in a planting period. In the invention, arginine, cystine, aspartic acid, vitamin B1 and vitamin B2 serve as nutritive components, and hexanoic acid 2-(diethylamino) ethyl ester, dimethyl sulfoxide, salicylic acid, choline chloride and betaine form a material combination capable of regulating physical activities of crops. The two kinds of components are used in combination, so that organic nutrients the plants lacks under a drought condition can be supplied directly, plant type can be regulated, the drought resistance in the crops can be improved, and the yield of the crops is increased. The preparation can be used for soaking seeds or sprayed or sprinkled.
