Problems solved by technology

Thereby cutting propagation of American red ash (Fraxinus pennsylvanica Marsh) is still a technical problem in the seedling production at present, and this field is still blank, so the method of developing Luwa No. 5 (Fraxinus pennsylvanica Marshlula5) hard branch cutting propagation and improving the survival rate of cuttings are still urgently to be solved at present subject

Embodiment 1

[0027] 1. Selection and preparation of cuttings: On June 19, the healthy, pest-free, 20-year-old secondary branches of Luwa No. 5 were collected as cuttings, and 30 cuttings were collected. Pruning branches: cut the upper end of the cutting branch 1-1.5cm above the first node, and cut the lower end of the branch 0.5-1cm below the node, leaving 2 leaflets on each branch, and cutting off the first half of each leaflet part, and the average length of the branches is 10-12cm, and the cutting branches are prepared for subsequent use;

[0028] 2. Seedbed establishment and cutting matrix preparation: build a seedbed with a height of 80cm as a cutting propagation area, stir the cutting matrix and sprinkle it into the seedbed, and make the thickness of the matrix reach 45cm, and then sprinkle a layer of 5cm thick on the upper layer of the matrix. Sand, standby; Wherein, described cuttage matrix is ​​made by sand: perlite: peat is mixed in the ratio of volume ratio 4:1:1, is sterilized ...

Embodiment 2

[0035]Select 1-year-old branch except that cuttings, all the other operations are identical with embodiment 1, after 2 months statistics result, rooting rate is 93.3%, and 1-year-old cuttings are obviously higher than 2-year-old rooting rate.

Embodiment 3

[0037] Select 1-year-old branch except cuttings, in the cuttings treatment process, special-effect rooting powder solution concentration is 1000ppm, soaks 1min and 5min, all the other operations are identical with embodiment 1, statistical result after 2 months, rooting rate is respectively 53.3% and 36.7%.

Abstract

The invention discloses a method for hard wood cutting seedling of fraxinus pennsylvanica marsh lula 5. The method comprises the following steps of selecting 1 to 2-year's old fraxinus pennsylvanica marsh lula 5 hard branches with a tree age of 10 to 20 years as cutting shoots; trimming the branches to obtain the branches with the average length of 10 to 12cm; after soaking the trimmed branches for 12 hours in ascorbic acid and indolebutyric acid, soaking the branches for 3 minutes in a specific root-growing power solution; performing cutting on the branches in a specially prepared cutting medium; after cutting, spraying water onto the branches, and entering a seedling management stage. The technical requirement of the method provided by the invention is simple, the problem of low fraxinus pennsylvanica marsh lula 5 cutting survival rate affected by a secondary metabolite, such as tannin, is effectively solved, the root-growing rate of fraxinus pennsylvanica marsh lula 5 hard wood cutting is up to 93.3 percent, and the method provides technical support for plant seedling of fraxinus pennsylvanica marsh lula 5 seed seedlings and has very high application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for growing seedlings of Luwa No. 5 hard branch cuttings. Background technique [0002] Fraxinus pennsylvanica Marshlula5 is a deciduous tree of the genus Fraxinus in the oleaceae family, and is one of the preferred tree species for afforestation and landscaping in saline-alkali land. There are more than 70 species of white wax in the world, and about 34 species in my country, all over the provinces. Among them, Luwa No. 5 is an excellent new variety of white wax selected from the American red ash (Fraxinus pennsylvanica Marsh) cultivated in Shandong Province in 2011 by the Shandong Academy of Forestry Sciences for more than 20 years. It is a male plant with a straight trunk and a beautiful tree appearance. Fast-growing, the growth volume is 130% larger than ordinary white wax, drought-resistant, salt-tolerant, and has a wide range of adaptability. ...
