Dendrobium officinale seedling cultivation matrix and preparation method for same

Abstract

A dendrobium officinale seedling cultivation matrix and a preparation method for the same are provided. The cultivation matrix comprises the following parts according to weight by parts: 40 to 50 parts of cedar skin, 10 to 24 parts of peanut coat, 15 to 30 parts of moss, 8 to 18 parts of silver sand, 12 to 19 parts of vermiculite and 2 to 5 parts of super absorbent resin. The preparation method is that raw material is weighed; the cedar skin, the peanut coat, the moss, the vermiculite and the silver sand are evenly mixed, immersed into ethanol solution and cleaned by clean water, and then immersed into plant disinfecting mixing liquid for backup, wherein the plant disinfecting mixing liquid is formed through mixing of asparagus extraction liquid and saffron crocus extraction liquid; and the mixture and the super absorbent resin are illuminated for 1 to 3 seconds by plasma and then dendrobium officnale seedling cultivation matrix can be achieved. The dendrobium officinale seedling cultivation matrix requires low cost and the preparation method is simple; seedlings can be effectively protected due to the pure plant disinfecting mixing liquid and affection by insects and diseases can be avoided; the matrix processed by plasma illumination has a great water retention property and a fertilizer maintaining property.

Description

technical field [0001] The invention belongs to the field of plant tissue culture, and in particular relates to a dendrobium officinale seedling cultivation substrate and a preparation method thereof. Background technique [0002] Dendrobium officinale is a rare and endangered medicinal material with high added value. It is recorded in the classics. In the first year of Tang Kaiyuan, the Taoist classic "Tao Zang" included nine Chinese immortal grasses (Dendrobium officinale, Tianshan snow lotus, Sanliang ginseng, 120-year-old Polygoni multiflorum, Poria cocos of the sixtieth year, Cistanche deserticola, Shenshan Ganoderma lucidum, sea pearl, and Cordyceps sinensis). Dendrobium officinale has a remarkable effect of nourishing yin and tonifying deficiency, and is listed as the first of the "Nine Chinese Grass Immortals". Li Shizhen's "Compendium of Materia Medica" records: "Strengthening yin and benefiting essence. Take it for a long time, thicken the stomach, nourish the ...

AI Technical Summary

Problems solved by technology

[0003] As a commonly used Chinese herbal medicine, Dendrobium has a large market demand and a long growth cycle. Although the growth of Dendrobium seedlings has been improved through callus culture, the reproductive coefficient of Dendrobium plants is low, and the annual output is limited, entering the peak production period. The time is long, the scale cannot be formed, and the output is extremely limited, so the artificial cultivation technology still needs to be improved

[0004] The existing Dendrobium candidum is mostly made of fir bark or pine bark, mixed with supporting gravel or ceramsite as the cultivation substrate, but the gaps doped with gravel or ceramsite are large, and the fir bark or pine bark absorbs water. It is easy to fall into the gap and press on the root system. Not only can it not be made into young seedlings, but it is also not conducive to the growth of the root system, especially the growth of the root system of seedlings.

[0005] The Chinese patent with publication number CN103704150A discloses a special substrate for the cultivation of Dendrobium candidum and its application. The substrate for the cultivation of Dendrobium candidum is prepared by using the Chinese fir bark waste in Chinese fir processing, supplemented with balsa wood particles and small gravel, although the substrate is loose, Excellent air permeability, fertilizer retention, water retention and other properties, and low cost, but the bactericidal and antibacterial ability of the matrix is ​​poor, which is not conducive to the protection of tissue culture seedlings
