Problems solved by technology

[0004] In recent years, the scale of industrialized planting of Astragalus membranaceus has been expanding year by year, but the scale and technology of Astragalus membranaceus seedlings are seriously lagging behind, and they are still stuck in the traditional extensive original seedlings and planting stage. This backward planting method relies more on natural cultivation and imperfect management, resulting in Degradation, unstable medicinal ingredients, large differences, and low yield; in order to solve the above problems, the soilless cultivation technology of Astragalus came into being, especially the development of water culture seedling technology has expanded the scale of Astragalus seedlings, increased the survival rate, and shortened the seedling cycle. shortened, has good application development prospects
[0005] However, in the process of artificial cultivation of Astragalus membranaceus, the germination process of Astragalus membranaceus seeds, as well as the hydroponic nutrient solution, and the development of hydroponic conditions are not perfect, resulting in low germination rate of Astragalus membranaceus seeds, unstable survival rate of Astragalus membranaceus seedlings, and long growth cycle. Long, and the active ingredient is unstable

Abstract

The invention provides a method for raising astragalus seedlings with high flavone content. The method comprises the steps of germination of astragalus seeds and culture of astragalus seedlings. By optimizing the composition and proportion of an astragalus water culture nutrient solution, a nutrient solution suitable for nutrient elements required by growth of the astragalus seedlings is screened,and rapid growth of the astragalus seedlings is promoted; furthermore, by optimizing the technological conditions of astragalus seedling raising, especially pretreatment of the astragalus seeds and application of blue light and yellow light in the seedling raising process, the germination rate of the astragalus seeds is increased, the survival rate of the raised seedlings is increased, the flavone content in the astragalus seedlings is increased, and the method has high market application value.

Description

technical field [0001] The invention relates to a method for growing seedlings of plants, in particular to a method for raising seedlings of astragalus with high flavonoid content, and belongs to the technical field of plant cultivation.
