Enhance the stress resistance of crops, and have obvious effects on cold resistance, drought resistance and disease resistance.

The fulvic acid can effectively regulate the closure of plant stomata, and can automatically close the stomata of the epidermis under drought conditions, reducing the evaporation of water and achieving drought resistance. At the same time, fulvic acid can promote the synthesis of chlorophyll and mitochondria in plant leaves, enhance the photosynthesis and growth metabolism of plants, and greatly enhance the resistance of plants.
