Embodiment 1

[0020] A method for breeding fine varieties of Scrophulariaceae in this scheme is characterized in that it comprises the following steps:

[0021] 1) Plant screening: when Scrophulariaceae is mature, select plants without pests and diseases;

[0022] 2) Pretreatment and disinfection: The screened Scrophulariaceae take the sub-buds wrapped in white scales, without cracks, and the length is longer than 3cm, wash them with clean water, peel off the scales layer by layer, rinse the sub-buds with 70% alcohol for 30s, Then soak in 20 times sodium hypochlorite solution for 9 minutes, and rinse 4 times with sterile water;

[0023] 3) Stem tip stripping: Place the shoot tip of the seed buds treated in step 2) under a microscope, soak them in alcohol, then burn and cool them with tweezers and scissors, peel off the outer leaves of the seed buds, and cut out 0.2mm strips There are 2 leaf primordium shoot tips, and then wash it 3 times with sterile distilled water;

[0024] 4) Cultivati...

Abstract

The invention discloses a method for breeding an improved variety of scrophularia ningpoensis Hemsl., and solves problems that due to long time asexual reproduction of scrophularia ningpoensis Hemsl. in the prior art, virus accumulation is serious, and the yield and the quality are reduced. The method comprises the following steps: 1), screening plants, wherein the pest-free plants are selected; 2) pre-treatment and disinfection, wherein scale-peeled buds are soaked with the 20-time sodium hypochlorite solution for 8-10 min; 3) stem tip peeling, wherein each stem tip with 1-2 leaf primordium are cut; 4) cultivation, wherein the stem tips are placed in a culture medium for cultivation; 5) exercised seedling transplantation, wherein the seedlings are cultivated in the sun, then the seedlings are transplanted to a matrix to be cultivated for 15 days, and finally the seedlings are transplanted to a field. Compared with the conventional asexual reproduction method for scrophularia ningpoensis Hemsl., the yield and the quality of the scrophularia ningpoensis Hemsl. seedlings cultivated by the method are greatly improved.

Description

technical field [0001] The invention belongs to the field of planting Chinese herbal medicines, and in particular relates to a method for breeding fine varieties of Scrophulariaceae. Background technique [0002] Scrophulariaceae is the dried root of Scrophulariaceae Scrophulariae (Scrophularianingpoensis Hemsl.), which was first recorded in "Shen Nong's Materia Medica". It is a unique species in my country. It is only naturally distributed in China. It is cultivated in most parts of the country. It is mainly produced in Zhejiang, Anhui, and Hubei. , Guizhou and other places. It is a commonly used bulk medicinal material. As a raw material of Chinese patent medicine, it can produce dozens of Chinese patent medicines such as Tianwang Buxin Pill, Tianma Pill, Mailuoning, Qingyanhou Mixture, etc. Now it is also used in the production of cosmetics as a plant lubricant, antifreeze, anti Wrinkle cream etc. [0003] The reproduction method of wild Scrophulariaceae is to use seeds ...
