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 sweetgum sweetgum more than two years old, and then graft the scion of the required sweetgum sweetgum variety on the rootstock, so it takes a long time for seedling cultivation period; in recent years, some scholars have carried out experiments on the cutting propagation of sweetgum sweetgum twigs in North America. The cuttings of twigs are in the high temperature period in summer, and they need to be equipped with full-light spraying system devices before implementation. This method greatly limits seedling production enterprises and seedling farmers Large-scale Breeding of Liquidambar Seedlings
The hard branch cuttings of sweetgum sweetgum are easy to implement, easy to operate, and low in propagation cost; after literature search, there is no report in China

Embodiment 1

[0018] (1) Cutting time: from mid-March to the end of March in spring, when sweetgum sweetgum has not yet sprouted;

[0019] (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;

[0020] (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;

[0021] (4) Preparation of cuttings: Select the middle and upper part of the sweetgum sweetgum crown, which is robust, full of side buds, and free from diseases and insect pests. 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...

[0027] (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;

[0028] (4) Preparation of cuttings: Select the middle and upper part of the sweetgum sweetgum crown, which is robust, full of side buds, and free from diseases and insect pests. 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 s...

Embodiment 3

[0032] (1) Cutting time: in the spring from mid-March to the end of March, the North American sweetgum has not yet sprouted;

[0033] (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;

[0034] (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;

[0035] (4) Preparation of cuttings: Select the middle and upper part of the sweetgum sweetgum crown, which is robust, full of side buds, and free from diseases and insect pests. Cut the branches with a length of 12cm and a diameter of 0.8cm 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 cutti...

Abstract

The invention discloses a North America sweetgum hardwood cuttage seedling raising method. The method comprises the following steps that (1), cuttings are prepared; (2), cuttage media are prepared; (3), rooting agents are prepared; (4), the cuttings are processed and cuttage is conducted; (5), management after the cuttage and transplantation are carried out. According to the North America sweetgum hardwood cuttage seedling raising method, the survival rate of the cuttage is more than 80%, and the cost of the method is reduced by 40-50% compared with the cost of a North America sweetgum softwood cuttage method; the North America sweetgum hardwood cuttage seedling raising method is easy and convenient to operate and implement, has the advantages of being low in cost, simple in technical requirement, easy to popularize and apply and the like, and has important application and popularization value for North America sweetgum seedling breeding production.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for raising seedlings by cutting hard branches of sweetgum sweetgum. Background technique [0002] North American sweetgum (Acer palmatum) is a deciduous tree or small tree of the genus Acer in the family Aceraceae. It is native to the provinces of the Yangtze River Basin in my country, and is also distributed in Japan and South Korea. Sweetgum sweetgum is a world-renowned foliage tree species with beautiful appearance and peculiar leaf shape. In spring and autumn, the garden is full of colorful leaves. There are many varieties of sweetgum gardening in North America, and the landscaping application is extremely extensive. [0003] The asexual reproduction of plants can maintain the excellent characteristics of the female parent. The asexual reproduction methods of sweetgum sweetgum include tissue culture, grafting and cuttings. Among them, the technical req...
