The invention discloses an anti-drought, anti-disease and detoxication plant growth and protection chemical, which consists of moisturizing agent, virus tolerance agent, growth accelerating agent, nitrogen synergist, nutrient activating agent, humic acids, nitric acid rare earths and medium microelement; the moisturizing agent which undergoes the copolymerization reaction, decompression and drying processes is evenly mixed with other constituents according to a certain percentage, then the mixing agent undergoes measuring and packaging processes to become the anti-drought, anti-disease and detoxication plant growth and protection chemical. The invention combines all special activities of all constituents, achieves best comprehensive and balance functions, gives full play to the corresponding united and synergistic effects of all constituents, improves plant physiological functions, boosts plant growth and development, prevents and cures plant diseases, removes toxins from plant body, keeps soil moisture, activates soil nutrients, increases utilization rate of fertilizers, prolongs fertilizer efficiency period and lowers pollution on the environment. The invention is capable of being used with other fertilizers, which resolves the problem of the comprehensive and balance fertilization, creating or improving the living conditions needed for plant growth and protection, lowering costs caused by such harms as drought and diseases etc. and greatly increasing the crop yield.
