Wild imitation cultivation method of dendrobium officinale tissue culture seedlings

Abstract

The invention discloses a wild imitation cultivation method of dendrobium officinale tissue culture seedlings. The method comprises the following steps: selecting seedlings, airing seedlings, cutting boards, planting seedlings, fixing roots and performing transplanting. After the seedlings are selected, cleaned and aired, the seedlings are directly fixedly planted and bound on the cut boards with barks; then the seedlings are suspended collectively in a domestication greenhouse for domestication; and after the roots of the dendrobium officinale tissue culture seedlings are fixed, the domesticated dendrobium officinale tissue culture seedlings and the boards with barks are transplanted to a suitable field environment for wild imitation growth. The method leaves out a step that greenhouse seedbed domestication must be performed on tissue culture seedlings in traditional methods, reduces the production processes, saves a large amount of investment of manpower, material resources and financial resources, greatly reduces the production cost, and shortens the production time. The tissue culture seedlings cultivated by the wild imitation cultivation method has a high survival rate and wide transplanting range, and the method is simple and convenient, has high operability, is good in safety and reliability, and is high in survival rate, and the post-seedling phenomenon is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of imitating wild cultivation of Dendrobium officinale, in particular to a wild imitating cultivation method of Dendrobium officinale tissue culture seedlings. Background technique [0002] Dendrobium officinale is a rare and precious Chinese medicinal material. It is known as "Dendrobium", "Plant Gold" and "Healthy Soft Gold". It is listed as "Chinese Medicine" because of its efficacy, extremely rare, special living environment and outstanding nourishing effects. The first of "Nine Great Immortals" is called "Medicinal Giant Panda" by the international medicinal plant community. Especially for nourishing yin and lungs, nourishing stomach and body fluid, strengthening brain, eyesight, and replenishing the five internal organs; it has special effects on excessive tobacco and alcohol, overwork, excessive nightlife, overuse of eyes and brain, hoarseness of vocal cords, etc.; for human lung cancer Cells, atrophic ga...

Problems solved by technology

At present, regarding the tissue culture of Dendrobium candidum, the technology has gradually matured and stabilized. Since the tissue culture of Dendrobium candidum is carried out in an artificial environment, its medicinal value is far less than that of wild Dendrobium candidum, so it is necessary to use Dendrobium candidum is planted by imitating the wild method, but there are still various technical defects and drawbacks for the imitation wild cultivation method of Dendrobium candidum

[0004] For example, the invention patent with publication number 105960973A disclosed on September 28, 2016 discloses a cultivation method of Dendrobium huoshanense under natural forests. Branches are cut off from the junction with the trunk, and a triangular incision is cut at the trunk for grafting; the invention patent published on January 4, 2017 with the publication number 106258885A discloses a method for imitating wild cultivation of Dendrobium officinale, which is to use Dendrobium candidum is fixed on the moso bamboo for more than 1 year as the carrier of the epiphytic cultivation of Dendrobium candidum. In October of the lunar calendar, the seedlings of Dendrobium candidum are fixed above the bamboo nodes of moso bamboo; the invention patent with the publication number 106376443A disclosed on February 8, 2017 A kind of imitation wild planting method of Dendrobium officinale, it selects the withered upright tree, directly transplants and fixes the Dendrobium on the upright tree, plants 10 seedlings in each layer, arranges them evenly along the ring shape of the upright tree, and carries out artificial fertilization management, just imitates Part of the growth characteristics of wild Dendrobium is actually planted in the field, and the above two cases are directly planted in the wild. Due to the influence of the natural environment, the time for planting seedlings is relatively limited and the survival rate is low.

[0005] The common shortcomings of the above-mentioned various methods are: 1) the procedures are complicated, inconvenient to operate, and inefficient, especially in the unfavorable conditions in the field to bind and climb the tree (such as tree height, steep slope, cliff, etc.), the operation implementation 2) The survival rate is low and the cost is high. Grafting or binding directly to the tree in the wild will result in high mortality and slow growth. The waste of Dendrobium seedlings is serious, and the follow-up seedling replacement workload is heavy, which seriously increases manpower, Material and financial costs; 3) The imitation of wild cultivation places is very limited, not all trees or stone walls are suitable, such as trees with oil or gel, smooth-skinned trees or stone walls, etc., are not suitable for conventional methods of transplanting, It is not easy to widely promote and apply
