Problems solved by technology

This method has obvious shortcoming: the first, because the field environment is harsh, the pollution after picking strip inoculation is all more serious (contamination rate is more than 50%)
Second, the physiological state of the branches selected by this method is obviously affected by the adult mother plant, and the maturation effect is more significant, which is not conducive to the induction of seedlings.
[0011] 2. In large-scale tissue culture production, with the increase in the number of transfers of bottle seedlings, serious endophyte pollution will gradually appear. If it is not dealt with in time, it will cause great losses to production
However, in the process of industrial seedling cultivation, this treatment method has obvious disadvantages: first, different fungi will cause different pollution, and the types and concentrations of antibiotics selected will be different according to the polluted fungi and different pollution degrees , it is very difficult to operate finely in actual production, and it takes a lot of manpower to sort and process. From the perspective of cost, it is often not worth the candle
The disadvantages of this method are obvious: firstly, the cost of electricity is high, and the expenditure on electricity accounts for a large part of the cost of tissue culture; secondly, the growth state of the seedlings is poor, and the light quality of artificial light sources is far inferior to natural ones due to insufficient wavelength bands. light source, the cultivated seedlings are relatively thin and prone to vitrification, which is especially obvious in the cultivation of the species of Jiangzi
In addition, seedling hardening must be carried out for a certain period of time before the bottle seedlings are transplanted, which increases the emergence time.

Embodiment 1

[0037] 1. Preparation of light culture room

[0038] The top and surroundings of the natural light cultivation room are generally made of light-transmitting sunlight panels or glass, which can ensure sufficient illumination. Install a pair of shading nets with 90% shading rate on the top layer, install a pair of shading nets with 50% shading rate on the second layer, and install one deck of shading nets on the top of the cultivation frame (use thicker cloth from April to September). , October-March of the following year can use yarn). Around the cultivation room, a double-layer shade curtain is established, one layer is a thick cloth with a shading rate of 75%, and the other layer is a tulle with a shading rate of 30% (similar to a household double-layer curtain). Through different combinations and matching of the top three layers of shade nets and the surrounding two layers of shade curtains, various light intensities required for our seedling cultivation can be obtained.

Abstract

The invention relates to the technical field of plant culturing, and concretely relates to a method for rapidly breeding Litsea mollis by using tissue culturing. The method comprises the following steps: 1, culturing room preparation; 2, explant material screening and treatment; 3, induction culturing; 4, propagation culturing; 5, rooting culturing; and 6, nursery stock transplanting. The method successfully realizes the tissue culture large scale fast breeding of the Litsea mollis, and can realize all-year production of excellent Litsea mollis tissue culture plants, the all-illumination tissue culture seedling growing method almost omits all illumination power, greatly reduces the power cost and effectively solves the expensive electricity charge in the tissue culture production, shading articles used in the invention are cheap, simple and easily available, and the shading method is convenient and simple, and is easy to learn.

Description

technical field [0001] The invention relates to the technical field of plant culture, in particular to a method for rapidly propagating A. tomentosa by using tissue culture. Background technique [0002] Litsea mollifolia Chun (litsea mollifolia Chun), a small deciduous tree belonging to the family Lauraceae. At present, there is no report on the tissue culture research of A. tomentosa at home and abroad. The research on tissue culture of plants of the same genus found that Litsea Cubeba is easier to establish a tissue culture and rapid propagation technology system, but there is still a large gap in the establishment of tissue culture systems such as Poplaria japonica and Sichuan japonica in order to achieve large-scale production. Because there is no report on the tissue culture of Fructus Rhizoma Pachyphyllum, thus can only refer to the plant of the same genus, the prior art scheme similar to the present invention is an academic paper "Research on Tissue Culture Technolo...
