Background

Compared with the prior art, the plant growth regulator has the advantages of low cost, high benefit, labor saving and the like, is widely applied to the production of economic crops, grain and oil crops, vegetables, fruit trees, horticultural crops, medicinal materials and edible fungi, and makes important contribution to the increase of both production and income of farmers and the improvement of economic benefit.

Vitamins are a kind of essential organic compounds required by biological metabolism, most of the vitamins can be synthesized by the plants themselves, and the vitamins can be used as the prosthetic group of various enzymes in the plants, participate in the metabolism and energy transfer of various substances in organisms, play an important role in the growth process of the plants, influence the whole growth process of crops, and can not be separated from the vitamins from seed germination, root growth, flowering and pollination, cell division, quality, reproduction, stress resistance, disease resistance, hormone synthesis and the like. Vitamins are distributed in the plant body like nutrient elements in different parts of the plant, but are not present in as much amount as nutrient elements. Although plants can synthesize various vitamins required by themselves, the synthesis of vitamins is weakened or inhibited under the condition that the plants are stressed by various adversities, and the vitamins are important substances participating in the antioxidant system and metabolism of the plants. The action mechanism of vitamins is relatively complex, the effects are also many, common water-soluble vitamins such as vitamin B1 (thiamine), vitamin B3 (nicotinamide), vitamin B6 (pyridoxal), vitamin B9 (folic acid), vitamin C (ascorbic acid), vitamin E (tocopherol), vitamin P (bioflavonoid) and the like have the main effects of promoting the growth of roots, stems and leaves of crops, improving the oxidation resistance and promoting the resistance of the crops to diseases, and the manufacturing and the report of a plant growth regulator taking vitamins as main components are not seen in the market at present.
