Problems solved by technology

However, due to the traditional method of promoting germination of Chinese fir, the high-quality explants (scion) that can often be obtained are very limited, which seriously affects the propagation and application of excellent Chinese fir clones.

Embodiment Construction

[0021] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0022] Such as figure 1 A simple schematic diagram of the implementation process of the present invention is shown.

[0023] Such as figure 1 , the Chinese fir 1 cultivated in the traditional production practice will germinate a certain amount of Chinese fir shoots 3 at the position of the root 2, and these shoots can be directly used for tissue culture or cutting propagation after being cut, but because the shoots grow from the Chinese fir 1 Directly below the treetops, the growth is often weak due to insufficient light, and the number of shoots is small, resulting in low reproductive efficiency.

[0024] The present invention promotes the method for Chinese fir root root germination, carries out according to the following steps:

Abstract

The invention discloses a method for promoting fir root germination. The method includes the first step of choosing a fir root in the due north or due south direction and vertically inserting a supporting column on the position with the horizontal distance 20 cm to 25 cm from the root, the second step of slowly bending the trunk of a fir towards the direction of the supporting column until an included angle ranging from 20 degrees to 30 degrees is formed between the trunk of the fir and the ground, the third step of tying the crossed portion between the fir and the supporting column tightly through a rope, the fourth step of winding the portion, below the crossed portion, of the trunk of the fir by one to two circles through cloth, the fifth step of enabling the fir root to be covered with nutrient soil with the thickness of one centimeter to two centimeters, and the sixth step of trimming a coppice shoot on the fir root for vegetative propagation. According to the method, high-yield and high-quality fir explants (scion wood) can be obtained, the quick and efficient vegetative propagation of excellent fir clones obtained through researching and screening can be achieved, and large-area popularization and application in production practice can be achieved.

Description

technical field [0001] The invention belongs to the research field of Chinese fir asexual reproduction, in particular to a method for promoting the root germination of Chinese fir. Background technique [0002] Chinese fir[ Cunninghamia lanceolata (Lamb.) Hook] is an important timber tree species endemic to my country. It has a wide range of natural distribution and has the characteristics of fast growth, strong germination, early maturity, wide application, and high yield. It occupies an extremely important position in conifer plantation. For a long time, a large area of ​​pure Chinese fir forest has been built in southern my country. With the continuous increase of its continuous planting area and algebra, the output of large-diameter timber forest is decreasing day by day, and a series of ecological problems such as forest land decline and soil poisoning are becoming more and more serious. In order to realize the ecological cultivation of fast-growing and high-yielding ...
