Cultivation method of Dendrobium officinale

Abstract

The invention discloses a cultivation method of Dendrobium officinale. Natural growth environment for Dendrobium officinale is simulated successfully, a cultivation bed is made of cement pantiles, substrate is made of pine bark, self-made nutrient solution is used as fertilizer, and accordingly supply of water and fertilizer is guaranteed, root rotting caused by waterlogging and damage of insects, rats, weeds and diseases are avoided, transplant survival rate of Dendrobium officinale seedlings reaches more than 98%, Dendrobium officinale grows fast and blossoms or grow stems and leaves, one to three years early, yield is high (yield per unit area is more than 250kg), content of effective ingredients is high, quality is good, and the problems of low transplant survival rate, growth slowness, low yield and high cultivation cost of Dendrobium officinale seedlings are solved. The cultivation method includes the steps of making the cultivation bed, making the culture substrate, fixation and distribution of the cultivation bed, planting Dendrobium officinale, management of water and fertilizer, insect damage control and harvesting.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method of dendrobium officinale. Background technique [0002] Dendrobium candidum wall.ex Lindl. is a perennial herbaceous plant of the genus Dendrobium in the family Orchidaeae. Dendrobium candidum has mysterious biological habits. It grows in the shade of cliffs and receives the aura of heaven and earth all the year round, absorbing the essence of the sun and the moon. Wild Dendrobium candidum is mostly distributed in tropical and subtropical regions such as East Asia, Southeast Asia, and Australia. In my country, it is mainly distributed in the mountainous areas of Guangxi, Yunnan, Guizhou, Anhui, Zhejiang, Sichuan and other places south of the Qinling Mountains and Huaihe River. Because of its harsh growth conditions, its natural output is extremely rare, and its wild resources are on the verge of extinction due to long-term over-excavation by the pe...

[0006] 2. Name: A cultivation method of Dendrobium candidum, Chinese patent application number: 200610048891.3, publication number: CN 1961632A, applicant: Cai Zhongyu, address: Room 1705, Building 165, South Railway Station Residence, Kunming City, Yunnan Province, abstract: a The cultivation method of Dendrobium officinale, the present invention puts the seeds of Dendrobium candidum into the culture medium of 1 / 2MS basic medium + NAA (a-formaldehyde acetic acid) + banana juice 4 agar, and transfers the formed protocorm into 1 / 2MS basic medium Medium 10 BA (6-section base gland) 10 banana juice 4 agar medium for the cultivation of small seedlings to medium seedlings and large seedlings respectively, and then the large seedlings are planted in the hole of the wall in a three-dimensional planting method according to clumps. Cultivation, the present invention overcomes the existing wild Dendrobium candidum growth existing poor environment, low yield, and slow time to become a useful product, and provides a method from breeding to cultivation to ensure good growth of seedlings in stages and ensure that large seedlings have good air permeability. Moderate light and sufficient nutrition can fully meet the epiphytic characteristics of Dendrobium officinale, ensure the medicinal properties of Dendrobium officinale, and realize the mode of economical, large-scale and high-yield production

[0008] Judging from the above-mentioned public documents, my country has achieved gratifying achievements in the tissue culture and artificial cultivation of Dendrobium candidum at present, but there are still problems such as a slightly low survival rate of Dendrobium candidum transplanted, a slightly slow growth rate, low yield, and low content of active ingredients. , restricting the industrialization, large-scale development and comprehensive utilization of Dendrobium officinale
