Physicochemical properties: white crystalline powder. The product is not miscible with strong alkaline substances, but with weak acidic substances. It is easily soluble in methanol, ethanol, chloroform, acetone, etc., with pH value of 5.4. Slowly stir the product in 5 liters of 95 degree alcohol until it is completely dissolved, then add 20 liters of water and stir again. The 25 liters of solution is 0.004% aqueous solution, which is diluted 1000 times when used. Toxicity: low toxicity to humans and animals. Acute oral LD50 ＞ 2000mg / kg, acute percutaneous LD50 ＞ 2000mg / kg in rats, and the fish toxicity is also very low
Purpose: biochemical research. It is a new type of plant growth promoter with high efficiency. At very low concentration, it can significantly increase vegetative growth and promote fertilization. Compared with some plant growth regulators currently used, it has the characteristics of safety, no harm, low effective concentration, high activity and can improve the nutritional composition of plants. It can promote the synthesis of IAA (indoleacetic acid), ABA (abscisic acid) and ethylene, promote cell elongation and expansion and thus promote the growth effect of plants (depending on plant species), inhibit senescence, break dormancy, promote seed germination, promote stem and leaf growth, promote root growth, and induce amphoteric flowers and female flowers. The field application experiments in different regions and different crops show that the yield of wheat can be increased by more than 10%, that of corn by more than 20%, that of rice by more than 10%, that of strawberry, watermelon and tobacco by more than 20%, and that of citrus and orange by 15%
Storage: 2 ~ 8 ℃
