Problems solved by technology

[0005] The present invention is in order to solve the problem that the seedling germination rate and emergence rate of the existing Samara oil tree are low, the seeds are wasted, and the investment is increased. At the same time, due to the lack of endogenous hormones, it is difficult to carry out twig cuttings. Produce new root etc. problem, provide a kind of method of vegetative reproduction of Samara oil tree

Embodiment Construction

[0015] The following is the specific implementation process of the present invention:

[0016] A method for asexual propagation of Samara oil tree, comprising the following steps:

[0017] 1. Build a seedbed: The substrate of the transplanting bed is an important factor affecting the survival rate of cuttings, and the substrate must be ventilated and permeable. Use bricks to build a seedbed about 40cm high, 2.5m wide, and the length is determined according to needs. Spread 10-15cm of stones at the bottom of the bed, 8-12cm of slag in the middle, and 10-20cm of river sand on the top. Spray pipes are laid between the seedbeds, and drainage is provided under the bed. For holes, some perlite and vermiculite with good thermal insulation properties can be added to the river sand. Disinfect the seedbed with 0.4% potassium permanganate one week before cutting and the day before.

[0018] 2. Preparation and cutting of cuttings:

[0019] 2.1 Selection and treatment of the mother tree...

Abstract

The invention relates to a plant breeding field, which in detail relates to a method of elaeagnus mollis asexual propagation, comprising following steps: building seed bed; collecting ear from parent tree; cutting collected ear in medium on the bed; spraying water on leaves of elaeagnus mollis, the water temperature is 20-30 Deg. C; fertilizing on leaves until ear grows out root. The invention employs technology of asexual propagation to breed more seedling in short time, moderates seedling bed's temperature and humidity to keep physiological balance for cottage ear, disinfects ear and treats it with plant growth hormone to provide bios and nutrition for ear rooting, and treats parent tree to promote formation and growth of adventitious root. It solves problems of difficult rooting of callus and low seedling rate. The invention is characterized by simple and fast propagation technique, low cost and high propagation rate.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for asexual propagation of Samara oil tree. Background technique [0002] Elaeagnus mollos. Diels belongs to the national second-class protected plants and is in an endangered state. Its survival and reproduction status and the reasons for endangerment are as follows: Elaeagnus mollos. Diels belongs to the family Elaeagnus mollos. The southern part of Shanxi Province and Huxian County, Shaanxi Province are unique tree species in my country, and were listed as the first batch of second-class key protected plants in the country in the 1980s. Samara oil tree originated in the ancient Tertiary period and is one of the relict plants after the Quaternary glaciation. It was first discovered by Giraldi of France in Laoyu Mountain, Huxian County, Shaanxi Province in 1899. It was named by Diels of Germany in 1905. It is only a hundred years since the discovery of Sam...
