Embodiment 1

[0035] The seedling raising of embodiment 1 jelly grass detoxification seedling

[0036] (1) Prepare the greenhouse for cuttings: In mid-March 2020, it will be carried out in the No. 1 solar greenhouse of the Pingyuan Base, with an average daily temperature of 15-26°C. The cultivation conditions in the controlled greenhouse are as follows: the temperature is 20-30° C., the humidity is 80-90%, and natural light is applied.

[0037] (2) Disinfection treatment of cutting substrate

[0038] Space cotton (2.4*2.4*3cm) for cuttings is diluted 1000 times with 50% carbendazim wettable powder, soaked for 2 hours, and taken out for later use. Space cotton has good water and air permeability, which is more conducive to the formation of callus at the base of cuttings and the rapid growth of roots.

[0039] (3) Prepare rooting nutrient

[0040] Dissolve boric acid, glycine, inositol, and sodium nitrophenolate in 10L of water according to the concentration of boric acid 2.0mg / L, glycine 2....

Embodiment 2

[0048] The breeding effect research of embodiment 2 different prescription rooting nutrient solutions

[0049] According to the experience of plant cutting propagation, rooting speed and growth state are the key factors for the rapid propagation of seedlings. Therefore, on the basis of preliminary screening of rooting agents in the early stage, we continuously adjusted the formula of rooting nutrient solution, and designed 9 kinds of rooting nutrient solution for investigation. experiment. Different rooting nutrient solutions have a great influence on seedling propagation speed and growth. Through comprehensive comparison, the formula of rooting nutrient solution is finally determined. The specific experimental process is as follows:

[0050] (1) Investigation experiment of rooting agent

[0051] Firstly, the effects of different concentrations and ratios of different rooting agents naphthaleneacetic acid (NAA), indole butyric acid (IBA), ABT rooting powder, potassium indole...

Embodiment 3

[0072] The breeding effect of embodiment 3 different cutting substrates

[0073] Adopting the cutting seedling raising technology of space cotton in the present invention can achieve 15 days of rooting and rooting, basically meeting the requirements of transplanting, short production cycle, low cost (0.06 yuan / block of space cotton), small manual workload in the cutting process, high efficiency, and easy cultivation process. Simple and easy to operate. In order to further verify the effect of the present invention, the applicant compared the space cotton and the traditional cutting substrate sandy loam experimentally.

[0074] At the beginning of April 2020, the cutting experiment was carried out in the No. 4 solar greenhouse of the Pingyuan Base, and the average daily temperature was 18-30°C. Adopt the intermittent spraying condition in embodiment 1, sunlight natural light cycle, open part of the sunshade net on cloudy days. During the experiment, the root development of th...

Abstract

The invention discloses an efficient seedling raising method for virus-free mesona chinensis seedlings and application of the efficient seedling raising method. The method comprises the following steps of cuttage medium disinfection treatment, rooting nutrient agent preparation, cutting slip treatment and cuttage, management after cuttage, transplanting and planting and the like. According to the method, the seedling raising period of the detoxified mesona chinensis seedlings can be greatly shortened, the breeding efficiency is greatly improved, and the seedlings suitable for transplanting can grow after 15 days of cultivation and management; the cuttage seedling rate reaches 100%, and the field transplanting survival rate is 99.0% or above; the method has the advantages of being simple and easy to operate, short in production period, low in cost, clean and sanitary, saving space and labor and the like, and is beneficial to popularization; and the cost is low and is only about 20% of the cost of a tissue culture method, rapid propagation of high-quality mesona chinensis seedlings is well achieved, and industrialized production can be preliminarily achieved. According to the method, an efficient propagation method can be provided for propagation of the excellent virus-free mesona chinensis seedlings, and an excellent seedling guarantee is provided for industrial planting of the mesona chinensis seedlings.

Description

technical field [0001] The invention relates to the technical field of asexual propagation of plant seedlings, in particular to a high-efficiency seedling-raising method and application of the virus-free seedlings of jelly bean jelly. Background technique [0002] Grass jelly (Mesona chinensis Benth.) is an important medicinal and edible plant resource, which is widely used. It is the main raw material of herbal teas such as Wanglaoji, Jiaduobao, and Qizheng. Guiling jelly, grass jelly honey, grass jelly, milk tea and other products are popular among consumers. They are green drinks to quench thirst in summer, and their sales are increasing year by year. Herbal jelly has good development and utilization value in medicinal and edible aspects. With the hot sales of herbal tea and other series of drinks and food, the planting scale of jelly jelly is increasing. [0003] Bean jelly has been cultivated on a large scale in Guangdong, Guangxi, Fujian, Jiangxi and other places in m...
