Fast cuttage propagation method for silkwood

Abstract

The invention belongs to the technical field of plant propagation, particularly relating to a fast cuttage propagation method for silkwood. The invention absorbs a theoretical basis of tissue culture, carries out cuttage on stock micro-propagation unit materials to a nursery bed to culture after the stock micro-propagation unit materials are treated through a rooting agent, and releases plant tissue culture from a laboratory to cause the plant tissue culture to directly go to production. The invention has the advantages of little explant amount, low propagation expansion cost, fast propagation speed, high survival rate, and the like and realizes continuous fast propagation all the year round. The method comprises the following steps: firstly, building a fast propagation greenhouse base, and taking perlite as cutting matrix; secondly, preparing propagation materials: taking and shearing annual or perennial lignification or semi-lignification hale branches into cuttings with the length of 2 to 4 cm, and leaving one leaf and one sprout for each cutting; thirdly, carrying out disinfection treatment for the nursery bed and the cuttings; fourthly, treating the cuttings with the rooting agent and rooting powder; fifthly, managing the nursery bed: after the cuttage, controlling water content of the matrix to be about 60 percent, the environmental humidity to be about 95 percent and the temperature to between 20 DEG C to 30 DEG C, and shading the cuttings with double layers through a shading net with the transmittance of 50 percent; and sixthly, testing and transplanting sprouts.

Description

1. Technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a rapid propagation method of nanmu cuttings. 2. Background technology [0002] Phoebe chekiangensis (phoebe chekiangensis) is an evergreen tree belonging to the genus Phoebe in the Lauraceae family. It is a national second-class protected plant and is the most precious kind of nanmu. The wooden structure of the Tiananmen Gate Tower in Beijing is all made of precious "golden nanmu" native to Hunan, Yunnan and other places in my country. my country has a long history of utilizing nanmu, and the artificial cultivation of nanmu is the thing in recent years. Due to the very small number of extant nanmu, and most of them are regarded as key cultural relics by governments at all levels, they are extremely precious. In recent years, with the rapid development of the nursery stock industry, some people of insight have explored and bred Phoebe nanmu seedlings un...

Problems solved by technology

In recent years, with the rapid development of the nursery stock industry, some people of insight have explored and bred nanmu seedlings under the guidance of forestry experts, mostly by seeds. Due to the limited number of seeds, the speed of reproduction is greatly limited.
