Problems solved by technology

Among them, the technical requirements of tissue culture are high, the operation is complicated, and the production cost is expensive; grafting propagation needs to cultivate the rootstock of Acer palmatum that is more than two years old, and then graft the scion of the required Acer palmatum variety on the rootstock, so it takes a long time to cultivate seedlings. period; in recent years, some scholars have carried out experiments on the cutting propagation of Acer palmatum twigs. The cuttings of twigs are in the high temperature period in summer, and they need to be equipped with a full-light spray system before implementation. This method greatly limits the seedling production enterprises and seedling farmers. Large-Scale Breeding of Acer palmatum Seedlings
Hardwood cuttings of Acer palmatum are easy to implement, easy to operate, and low in propagation costs; after literature search, there is no report in China

Embodiment 1

[0019] (1) Cutting time: from mid-March to the end of March in spring when Acer palmatum has not yet sprouted;

[0020] (2) Equip the cutting substrate: mix the vermiculite and peat at a volume ratio of 1:2 to make the cutting substrate, and spray and disinfect the cutting substrate by diluting 800 times of medicinal liquid with 50% carbendazim wettable powder;

[0021] (3) Prepare rooting agent: dissolve 200 mg of indole butyric acid in 20 ml of 95% ethanol, add 20 mg of manganese sulfate, vitamin B 1 After 3.0 mg, add water to 1 kg, mix well and make a rooting agent for later use;

[0022] (4) Preparation of cuttings: Select the middle and upper part of the Acer palmatum crown, which is 1 year old and strong, with full side buds and no pests and diseases. Cut the branches with a length of 8cm and a diameter of 0.3cm as cuttings. The upper and lower cuts of the cuttings are truncated, and the distance between the upper cut and the cut bud is 0.5-1cm. The cut is smooth. Each ...

[0028] (3) Prepare rooting agent: dissolve 400 mg of indole butyric acid in 40 ml of 95% ethanol, add manganese sulfate 30 mg, vitamin B 1 After 5.0mg, add water to 1kg, mix well and make a rooting agent for later use;

[0029] (4) Preparation of cuttings: Select the middle and upper part of the Acer palmatum crown, which is 1 year old and strong, with full side buds and no pests and diseases. Cut the branches with a length of 10cm and a diameter of 0.5cm as cuttings. The upper and lower cuts of the cuttings are truncated, and the distance between the upper cut and the cut bud is 0.5-1cm. The cut is smooth. Each cutt...

Embodiment 3

[0033] (1) Cutting time: in the spring from mid-March to the end of March, Acer palmatum has not yet sprouted;

[0034] (2) Equip the cutting substrate: mix the vermiculite and peat at a volume ratio of 1:3 to make the cutting substrate, dilute 1000 times with 50% carbendazim wettable powder, spray and disinfect the cutting substrate;

[0035] (3) Preparation of rooting agent: dissolve 300 mg of indole butyric acid in 30 ml of 95% ethanol, add 25 mg of manganese sulfate, vitamin B 1 After 4.0mg, add water to 1kg, mix well and make a rooting agent for later use;

[0036] (4) Preparation of cuttings: Select the middle and upper part of the Acer palmatum crown, which is 1 year old and strong, with full side buds and no pests and diseases.

Abstract

The invention discloses a seedling cultivating method for cutting hard woods of acer palmatum. The method comprises the following steps: (1) selecting an appropriate cutting time; (2) preparing a cutting substrate; (3) preparing rooting agent; (4) cutting slips processing and cutting; and (4) managing and transplanting after cutting. The seedling cultivating method for cutting the hard woods of the acer palmatum, disclosed by the invention, has the characteristics as follows: the cutting survival rate reaches more than 80%; compared with the cost of acer palmatum softwood cuttage, the cost of hard wood cuttage is reduced by 30-50%; the cost of hard wood cuttage is only about 20% of the cost of a tissue culturing method; and compared with a seedling cultivating period of the acer palmatum graftage, the seedling cultivating period of the hard wood cuttage is reduced by 2-3 years. The method disclosed by the invention has the advantages of simplicity, convenience and easiness in operation, low cost, simple technical requirements, easiness for promotion and application as well as important application and promotion values in acer palmatum seedling breeding production.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for growing seedlings by cutting hard branches of Acer palmatum. Background technique [0002] Acer palmatum (Acer palmatum) is a deciduous tree or small tree of the genus Acer in the family Aceraceae. It is native to the provinces in the Yangtze River Basin of my country, and is also distributed in Japan and South Korea. Acer palmatum is a world-renowned foliage tree species with beautiful posture and peculiar leaf shape. There are many varieties of Acer palmatum gardening, and the application of landscaping is extremely extensive. [0003] The asexual reproduction of plants can maintain the excellent characteristics of the female parent. The asexual reproduction methods of Acer palmatum include tissue culture, grafting and cuttings. Among them, the technical requirements of tissue culture are high, the operation is complicated, and the production cost is ...
