Method for promoting growth and development and increasing yield and quality of traditional Chinese medicinal materials by using photosynthetic microorganisms

Abstract

The application provides a method for promoting growth and development and yield and quality improvement of traditional Chinese medicinal materials by using photosynthetic microalgae, and belongs to the technical field of microalgae application. The application provides application of microalgae capable of photosynthesis in cultivation of traditional Chinese medicinal materials, wherein the microalgae are planted on leaves of the traditional Chinese medicinal materials by foliar spraying. The microalgae capable of photosynthesis can be planted on leaves of the traditional Chinese medicinal materials, thereby promoting growth and development of angelica sinensis; endogenous hormones and microbial community composition of the leaves are changed, thereby regulating rhizosphere soil microbial community structure and function, changing soil physical and chemical properties, thereby significantly promoting yield increase of the traditional Chinese medicinal materials, reducing diseases, improving effective component content, and effectively improving stress resistance. The application further provides a cultivation method of the traditional Chinese medicinal materials, wherein the microalgae fungicide is sprayed on leaves after true leaves grow or after transplanting; the method is not affected by environmental factors, soil types, farm operations and indigenous microorganisms, and has stable effect and saves time and labor.
