Cuttage seedling method for dendrobium candidum

Abstract

The invention aims to provide a cuttage seedling method for dendrobium candidum to increase the cuttage seedling percentage of dendrobium candidum branches, reduce the production cost of seedling, promote the planting popularization of the dendrobium candidum, meet the market requirement for the dendrobium candidum product and reduce the excessive digging and extracting for wild resources. The cuttage seedling method for the dendrobium candidum provided by the invention comprises the following steps: A, disinfecting the cut fresh dendrobium candidum branches growing for more than two years; B, performing dehydration treatment on the disinfected dendrobium candidum branches; C, accelerating germination of the dendrobium candidum branches after being subjected to the dehydration treatment; and D, planting the successfully germinated dendrobium candidum branches in a culture medium for culturing, thereby obtaining the survival seedling. According to the cuttage seedling method for the dendrobium candidum provided by the invention, the dendrobium candidum branches are especially limited to suitable dehydration treatment and prepared germination before the cuttage, so that the cuttage seedling percentage of the dendrobium candidum branches is greatly increased and the production cost of the seedling is lowered.

Description

technical field [0001] The invention belongs to the technical field of production of dendrobium candidum seedlings, and in particular relates to a cutting method for seedlings of dendrobium candidum. Background technique [0002] Dendrobium candidum is a traditional precious Chinese medicinal material in my country. Since ancient times, it has been listed as the first-class Chinese medicine together with Cordyceps, ginseng, and Ganoderma lucidum. The "Shen Nong's Materia Medica", which was written more than 1500 years ago, records: "Dendrobium is sweet, flat, and non-toxic. In the main injury, it removes numbness, lowers qi, nourishes five Zang deficiency and weakness, and strengthens yin. Long-term use thickens the stomach and lightens the spleen and stomach. Prolong life." Due to its wide range of functions, products such as Tiepi Fengdou are expensive in the market. [0003] Dendrobium candidum is an epiphytic plant of Orchidaceae, mainly distributed in Jiangxi, Guangxi,...

Problems solved by technology

Cutting propagation seedlings are generally selected in spring and summer, and the stems that have grown vigorously are selected, and a section that has bloomed is removed and cut into small sections. Each section of seedlings has 3 to 4 sections. The cuttings are placed in culture medium or fine sand, shading and keeping shade Under humid conditions, new shoots can grow on the nodes after a period of time, and can be transplanted when the root system of the new shoots grows 2 to 4 cm. However, in actual production, due to the high water content of the Dendrobium paper strips, the cuttings take a long time to germinate, which makes them susceptible to infection. The survival rate is greatly reduced
