Technical Field

The present invention belongs to a plant growth regulator composition and a preparation method thereof.

Background

Gibberellic acid is a broad-spectrum plant growth regulator composition, and GA containing gibberellic acid is widely applied to agricultural production₃Gibberellic acid GA₄And gibberellic acid GA₇Is promoting GA in flowering and fruit setting₃Greatest effect, secondly GA₄However, GA is present in promoting apple fruit set and pentagonal ridges₄And GA₇Most preferably. Gibberellic acid can promote the growth and development of crops, so that the crops mature early, the yield is increased, and the quality is improved; can rapidly break the dormancy of organs such as seeds, tubers and bulbs and promote germination; reduce the falling of buds, flowers, bolls and fruits, improve the fruit bearing rate or form seedless fruits. Some 2-year-old plants can also flower in the same year.

Forchlorfenuron belongs to cytokinin growth regulators. Can promote cell division, differentiation and expansion, promote organ formation and protein synthesis, improve photosynthesis efficiency, enhance stress resistance, delay aging, improve fruit setting rate, and promote fruit enlargement. Is suitable for fruit trees and melon and fruit plants.

Whereas in the prior art, GA is due to gibberellic acid₃The forchlorfenuron technical material is insoluble in water and soluble in organic solvents such as alcohols, so that the pesticide preparation for the traditional administration is generally processed into two dosage forms of emulsion or solution; volatile organic solvents are required to be uniformly added into both the missible oil and the soluble agent, and are toxic and harmful to human bodies and the environment, so that the pesticide has great harm to the human bodies and the environment.
