Plant growth nutrient solution

The invention discloses a plant growth nutrient solution. In the plant growth process, various diseases, such as bacterial wilt, banded sclerotial blight, mosaic disease, seasonal febrile diseases and the like, are generated because of factors of replanting in the old soil or the factors of air, running water, plant diseases and insect pests and the like. Especially, plants which are replanted in the old soil are lack of enough protection from plant endogenous hormones and active enzyme, thus the plants can not resist infection and invasion of various germs and viruses. In the plant growth nutrient solution, superoxide dismutase is combined with other plant growth hormones and regulators, and thus the plant growth nutrient solution has strong antioxidant capability and effect on accelerating plant growth. After the plant growth nutrient solution is applied on plants, in-vivo oxygen free radical content is lowered, toxic action on plants by the oxygen free radicals is lightened, the premature senility phenomenon of plants is eliminated, harm on plants by various germs and viruses can be prevented, and the quality and the yield of the plants are improved.
