Problems solved by technology

[0004] Based on this, some studies have used bryophytes including peat moss as a substrate to propagate cuttings of Vaccinium plants. However, not all mosses can be used as ideal substrates for cuttings of Vaccinium plants, and most of them use non-fresh active bryophytes as substrates. At the same time, various fungicides are added to the medium, so that the survival rate of seedling breeding is low, and the cutting effect is not ideal

Embodiment 1

[0016] (1) Selection and treatment of cuttings: Select the branches that are semi-lignified in the current year, thick and straight, full of leaf buds, and free from diseases and insect pests to make cuttings. The degree of lignification of the cuttings is low, which is conducive to the formation of callus. Then form young roots, the cuttings are 6cm long, quickly dip the cuttings with indole butyric acid or soak the base of the cuttings with naphthalene acetic acid for 2 hours.

[0017] (2) Substrate preparation: firstly, the mycorrhizal spores extracted from Vaccinium cranium were prepared into a mycorrhizal suspension and inoculated into a small amount of fresh sphagnum moss plants cultivated in the experimental facility, so that the endophytic mycorrhizae were in it. A large number of proliferation; then, use the moss that has been inoculated as the mother plant of endomycorrhizae to inoculate in the fresh peat moss culture substrate. The fresh peat moss substrate must mee...

[0022] (1) Selection and treatment of cuttings: Select the branches that are semi-lignified in the current year, thick and straight, full of leaf buds, and free from diseases and insect pests to make cuttings. The degree of lignification of the cuttings is low, which is conducive to the formation of callus. Then form young roots, the cuttings are 8cm long, quickly dip the cuttings with indole butyric acid or soak the base of the cuttings with naphthalene acetic acid for 2 hours.

[0023] (2) Substrate preparation: firstly, the mycorrhizal spores extracted from Vaccinium cranium were prepared into a mycorrhizal suspension and inoculated into a small amount of fresh sphagnum moss plants cultivated in the experimental facility, so that the endophytic mycorrhizae were in it.

Abstract

The invention belongs to the technical field of plant vegetative propagation, and particularly relates to a method for vegetative propagation of vaccinium plants through fresh sphagnum. The method is particularly applicable to rapid breeding of some main vaccinium plants. Half-lignified branches or tissue culture seeding stems of bilberry in that very year are selected and soaked in an indolebutyric acid, and then cuttings are arranged at the roots for 2 hours. A fresh sphagnum culture substrate is inoculated with endotrophic mycorrhiza extracted from the vaccinium plants. The cuttings are inserted in the fresh sphagnum culture substrate, and then plastic film mulching is conducted. After cuttage, the temperature is controlled to range from 15 DEGC to 28 DEG C, and relative humidity is controlled to range from 80% to 90%; after the cuttings take roots, liquid complete fertilizer with the concentration of about 0.5% is applied every 20 days. According to the method, the fresh sphagnum is used as the substrate for culture of seedlings of the vaccinium plants in a cuttage mode, the survival rate of the cultured seedlings of the vaccinium plants is increased by means of inoculating the substrate with the mycorrhiza of the vaccinium plants, and therefore it is guaranteed that strong and high-quality seedlings without pest and disease damage are cultured.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for asexually propagating Vaccinium plants by using fresh peat moss, and is especially suitable for rapid breeding of some main Vaccinium plants. technical background [0002] Vaccinium plants belong to the Rhododendron family and are usually small shrubs. Most of the fruits of this genus have delicate flesh, thin peel, very small seeds, juicy, sweet and sour taste, which can be eaten fresh or processed into jam, candied fruit, juice drinks, etc. In addition to conventional sugar, organic acid and vitamin C, its fruit is also rich in anthocyanins, vitamin E, vitamin A, vitamin B, SOD, protein, fat and other rare special ingredients in other fruits, as well as rich potassium and iron. , zinc, manganese and other trace elements. It plays an extremely important role in preventing myopia, enhancing heart function, anti-cancer, and anti-card...
