Description

A kind of method for promoting root growth of rhizome medicinal materials in plant factory

technical field

The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, in particular to a method for promoting the growth of tuberous roots of rhizome medicinal materials in plant factories.

Background technique

The cultivation of medicinal plants is the foundation of traditional Chinese medicine, which is related to people's livelihood and social stability, and is a manifestation of national advantages in global competition. In recent years, relevant departments have continuously increased the supervision of the Chinese herbal medicine market. In 2017, the former State Food and Drug Administration issued a total of 46 unqualified drug information, involving more than 1,000 batches of drugs from more than 500 drug manufacturers. However, the cultivation of many medicinal materials in my country mainly relies on the scattered planting of medicinal farmers, extensive planting technology, and blindly expanding the planting range, resulting in poor planting, serious degradation of germplasm characteristics, and low content of medicinal ingredients. The formation and accumulation of active ingredients in traditional Chinese medicine are closely related to the natural conditions of their growth.

According to statistics, the most popular types of medicinal materials in 2019: Salvia miltiorrhiza, Banlangen, Astragalus, Fangfeng, Mint, Polygonatum, Daqingye, etc. Popular types of medicinal materials: Honeysuckle, Astragalus, Salvia, Polygonatum, Ganoderma lucidum, Panax notoginseng, Codonopsis, etc. More than half of the above purchased and supplied medicinal materials are rhizome plants, but rhizome medicinal materials generally have a long planting cycle, high water and fertilizer requirements, and difficulty in controlling pests and diseases. Planting rhizome medicinal materials in plant factories can standardize planting management, provide a good planting environment, avoid the impact of the natural environment, artificially directional control quality, and make full use of land and artificial resources.
