Seeding and propagating method of lotus leaf adiantum spore

Abstract

The invention discloses a seeding and propagating method of a lotus leaf adiantum spore, and belongs to the technical field of forest propagation. The main technical point is to use lotus leaf adiantum spore as a material, apply a series of measures such as selection and disinfection of seeding matrix, disinfection of sowing container and drug and cultivation environment of seeding and emergence periods, and moisture management, so as to promote the spore seeding and propagating efficiency. The seeding and propagating method of the lotus leaf adiantum spore is simple in method, short in seedling time, high in seedling rate, high in survival rate of transplanting, and can reduce the production cost, and is significant to protect national rare and endangered species.

Description

technical field [0001] The invention relates to a practical technique for sowing and propagating Adiantum lotus leaf spores. Background technique [0002] Adiantum lotus leaf, also known as lotus leaf money grass and wire grass, is a unique species in China under the genus Adiantum in the family Adiantum. It is only distributed in the Three Gorges of the Yangtze River in my country, with an altitude of 80-430m. The rhizome of Adiantum lotus leaf is short and erect, with single leaves in clusters, kidney-shaped leaves, bright black petioles, small and chic for viewing; it also has important medicinal value for jaundice hepatitis, urinary system infection, otitis media, etc. The disease has a better curative effect. However, the natural reproductive ability of Adiantum lotus leaf is weak, and the number is scarce. After the construction of the Three Gorges Project, the original area below 175m above sea level will be submerged. In addition, due to human impacts such as immig...

[0003] Xu Huizhu, Wuhan Institute of Botany, Chinese Academy of Sciences, published "Spore Propagation of Rare and Specialty Plant Adiantum lotus in the Three Gorges Reservoir Area" in "Yangtze River Basin Resources and Environment", which discloses a method of sowing and propagating Adiantum lotus spores with high-quality leaf humus For the sowing substrate, it takes 110 days from sowing to the emergence of the first sporophyte seedlings, but this method is cumbersome and takes a long time to emerge, so there is room for further simplifying the process and shortening the time; Zhang Zurong of Chongqing University of Arts and Sciences published in "Anhui Agricultural Science" In the "Research on Spore Propagation Technology of Cymbidium and Adiantum lotus leaf", the native soil is used as the seeding substrate, and the emergence rate is as high as 46.6%, but this method is costly, and there is room for further improvement of the emergence rate
