Embodiment 1

[0047] Embodiment 1, the cutting fringe of ancient arborvitae groping

[0048] 1. Rooting rate of cuttings of Thuja arborvitae of different ages treated with different hormones

[0049] Auxin can obviously promote the occurrence and growth of adventitious roots and lateral roots. Since different growth hormones are not suitable for rooting of cuttings, and different plants have different adaptability to different growth hormones, therefore, choosing the appropriate type of growth hormone is important Cuttings of ancient oriental cypress trees are particularly important. Three hormones, ABT1, NAA, and NAA:IBA=1:1, which are more commonly used in cutting experiments, were selected as hormones, and the concentration design was divided into high concentration, medium concentration and low concentration.

[0050] ABT1 solution, NAA solution and NI solution (NAA:IBA=1:1) prepare different hormone solutions according to different concentrations, and the concentration design is divid...

Embodiment 2

[0127] Embodiment 2, 3000-year cutting propagation technology system of oriental cypress

[0128] 20 per treatment. Repeat 3 times.

[0129] Due to the age of the 3000-year-old arborvitae, cutting propagation is more difficult. On the basis of using cuttings of different ages of arborvitae to select a better hormone ratio and cutting treatment, further discuss the cutting propagation technology system of arborvitae, in order to use The cutting method makes it propagate successfully. During the cutting process, ABT1 and NAA:IBA (1:1), which are the better hormones in the above results, were selected to cut Cypress Regulus. During the cutting process, the growth of the cuttings was observed, and the number of rooting rates was used as an index, as follows:

[0130] In 2013, 3000-year-old arborvitae (Shanxi Xuanyuan cypress in Baidu Encyclopedia or "How much do you know about longevity in trees" and "Many wonders in ancient Chinese trees") were taken from the upper part of the...

Abstract

The invention discloses a cutting propagation method for an ancient platycladus orientalis. The method includes the steps: sequentially using potassium permanganate, sodium lignite and hormone for treating cuttings of the ancient platycladus orientalis to obtain treated cuttings; subjecting the treated cuttings to cuttage and cultivation in a matrix to realize cutting propagation of the ancient platycladus orientalis. According to experimental results, the cutting propagation method has the advantages that survival rate in clonal propagation of the ancient platycladus orientalis is increased, rooting time of the ancient platycladus orientalis is shortened, and references are provided for research on clonal propagation of other ancient trees.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a cutting propagation method of ancient arborvitae. Background technique [0002] Arborvitae has a long history of cultivation in my country. Ancient arborvitae with a lifespan of hundreds or even thousands of years are distributed in many parts of the country. The Arborvitae arborvitae over 3,000 years old has now entered its advanced age, and its tree vigor is very weak. How to effectively clone and reproduce the old Arborvitae to make it sustainable and valuable has become a common concern of Chinese people all over the world, and it has also become an urgent issue for local forestry departments. problem to be solved. The older the tree, the more difficult it is to take root From the perspective of domestic and foreign progress, there have been some studies on the cutting propagation of centuries-old trees. For example, the rooting rate of 600-year-old ginkgo cuttings is 8%...
