Description

Asplenium nidus culture medium and preparation method thereof

Technical Field

The invention relates to the field of fern culture medium, in particular to a asplenium nidus culture medium and a preparation method thereof.

Background

Asplenium nidus (Latin name: Asplenium nidus), a perennial large epiphyte, also known as Sophora davidii in Taiwan, is a species of Nectria of the family Orchidaceae, and belongs to perennial yin-growing herbaceous foliage plants. The plant height is 80-100 cm, the rootstock is upright, thick and short, is woody, is about 2 cm thick, is dark brown, and the tip is densely covered with scales; the scales are wide and acicular, have the length of about 1 cm, have gradually sharp tips, are full-edge, are thin and dark brown, and are slightly glossy. The asplenium nidus is native to southeast Asia, eastern Australia, eastern Indonesia, India and Africa, etc., and is widely distributed in tropical and subtropical regions such as Hainan, Taiwan, Guangxi, etc.

The pteris vittata is unique in shape and large in biomass due to the fact that the growth shape of the pteris vittata is like a nest, and is widely applied to garden appreciation and indoor air purification in recent years. The spore and tissue culture seedling of the bird nest fern in China are researched more, but the research on the culture medium is very little. At present, the culture medium of the asplenium nidus is mainly composed of leaf mold, peat soil, vermiculite, river sand and the like, scientific compatibility and systematic research are not available, and the asplenium nidus culture medium is easy to lose green; the pteris nidulans culture medium in the patent CN 101755661A is relatively conventional, and has insufficient nutrients, and the pteris nidulans grows slowly.
