Dendrobium fimbriatum cutting seedling method

Abstract

The invention discloses a dendrobium fimbriatum cutting seedling method which comprises the steps that cutting branch selecting is carried out, wherein triennial dendrobe branches are selected, and branch middle portions or top portions are taken; shoot cutting is carried out, wherein cutting ends of the dendrobium fimbriatum branches are subjected to oblique cutting by the angle of 30-60 degrees, then the cutting ends are soaked in an ABT rooting powder solution, and soaking time is 6 h; cutting propagation is carried out, wherein processed cutting branches are vertically inserted into a seedling culturing matrix where humic pine bark is paved; and seedling culturing management is carried out, a seedbed is subjected to watering every 5 days, temperature is controlled to be about 25 DEG C, humidity is controlled at about 60%, and when 3-5 roots grow at the cutting ends of the dendrobe cutting branches and buds start to grow from middle internodes, seedling transplantation can be carried out. The cutting branches are the middle portions or the upper portions of triennial dendrobe stem branches, material sources are wide, cost is low, local materials can be used, meanwhile, the selected seedling culturing matrix is the humic pine bark, the source is wide, cost is low, and seedling culturing effect is obvious.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings of Dendrobium tassel, belonging to the technical field of orchid seedling raising and transplanting. Background technique [0002] Dendrobium tassel (Dendrobium fimbriatum Hook .), also known as Dendrobium dendrobii, is a perennial epiphytic herb of the Orchidaceae Dendrobium genus. Dendrobium is not only a traditional and authentic precious traditional Chinese medicine, but also an important raw material for the production of traditional Chinese medicine today. Dendrobium tassel is mainly distributed in tropical and subtropical regions such as southern Guangxi to northwest, southern Guizhou to southwest, and southeastern Yunnan to southwest. In recent years, due to excessive excavation and its own growth and reproduction characteristics and special requirements for the growing environment, wild resources are on the verge of exhaustion. [0003] At present, in the artificial planting...

AI Technical Summary

Problems solved by technology

[0003] At present, in the artificial planting and production process of Dendrobium fringe, the breeding of Dendrobium fringe seedlings is mainly based on tissue culture, which has the disadvantages of high cultivation cost, harsh cultivation operation conditions (sterility is required), cumbersome operation, serious medium pollution, and long cultivation cycle. A series of problems such as the high cost of growing and selling seedlings hinder the commercialization of Dendrobium fringe seedlings
