Embodiment 1

[0029] S1. Seed harvesting: On June 20, 2018, the Fritillaria taibai capsules produced in Wuxi County, Chongqing City were harvested. The harvested capsules were all yellow or yellow-green and stored in a cool place;

[0030] S2. Stratification matrix configuration: Take the humus soil from the coniferous forest in Xiaojin County, Aba Prefecture, Sichuan Province (the water content of the humus soil is 40%) and pass it through a 4-mesh sieve. : 1 mass ratio, then add potato extract and mix according to the ratio of humus and perlite total weight 20ml / kg, and use this as the layering matrix for layering treatment (distilled water is used to reduce the water content of the layering matrix to adjusted to 40%);

[0031] The preparation method of potato extract: take 1 part of potato and 10 parts of water in parts by weight; clean the potato and cut it into 0.2-0.5cm thick slices, then add the sliced ​​potatoes and water into a container and cook After boiling for 3 minutes, filte...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is:

[0036] In step S2, the humus and perlite are mixed in a mass ratio of 4:1, and then the potato extract is added and mixed according to the ratio of the total weight of the humus and perlite to 18ml / kg, which is used as a layer for layering treatment Lamination matrix (adjust the water content of the lamination matrix to 32% with distilled water);

[0037] In step S3, the layering box containing the layering matrix and Taibai Fritillaria capsules is first placed in a constant temperature biochemical incubator at 20°C for 48 days, and then the temperature of the constant temperature incubator is set to 5°C to continue the layering 92 days for processing;

[0038] All the other are with embodiment 1.

[0039] The morphological maturity rate of Fritillaria taiba seed embryos evaluated in step S3 was 95%; the germination rate of field seeds counted in step S4 was 71.4%.

Embodiment 3

[0041] The difference between this embodiment and embodiment 1 is:

[0042]In step S2, the humus and perlite are mixed in a mass ratio of 6:1, and then the potato extract is added in a ratio of 22ml / kg of the total weight of the humus and perlite and mixed evenly, as the stratification of the stratification process. Substrate (adjust the water content of the laminated substrate to 60% with distilled water);

[0043] In step S3, the layering box containing the layering matrix and Taibai Fritillaria capsules was first placed in a constant temperature biochemical incubator at 10°C for 52 days, and then the temperature of the constant temperature incubator was set at 8°C to continue the layering 88 days for processing;

[0044] All the other are with embodiment 1.

[0045] The morphological maturity rate of Fritillaria taibai seed embryos evaluated in step S3 was 96%; the germination rate of field seeds counted in step S4 was 73.3%.

Abstract

The invention relates to a fritillaria taipaiensis seed seedling raising method, and relates to the technical field of medicinal plant cultivation. The technical problem that in the prior art, the artificial planting industry of fritillaria taipaiensis is slow in development due to the fact that the seedling raising efficiency of fritillaria taipaiensis is lower and the provenance supply is shortis solved. According to the method, it is selected that fritillaria taipaiensis capsules with colors from green to yellow are harvested about the summer solstice in June as seed sources, humus soil, perlite and a potato extracting solution are used for preparing a stratification substrate, stratification treatment is conducted, then land with the altitude being 1700-2100 m and the land gradient being 3-5 degrees is selected as a seedling raising land, and seedling raising and sowing are conducted. The morphological development maturation rate of fritillaria taipaiensis seed embryos treated bythe seedling raising method can reach 95% or above, and the field germination rate can reach 70% or above; and the seedling raising efficiency of the fritillaria taipaiensis seeds is improved, the problem of difficult supply of fritillaria taipaiensis seed sources is solved, and the development of the artificial planting industry of the fritillaria taipaiensis is promoted.

Description

technical field [0001] The invention relates to the technical field of medicinal plant cultivation, in particular to a method for raising seedlings of fritillary fritillaria. Background technique [0002] Taibai Fritillaria ( Fritillaria taipaiensis P. Y. Li) is a plant of the genus Fritillaria in the family Liliaceae. Its dried bulbs are used as medicine. It is one of the source species of the famous Sichuan medicinal material Fritillaria sichuanensis. In recent years, as the market price of Fritillaria fricariens has risen year by year, the wild resources of Fritillaria fringata have been over-exploited, the resources are gradually being exhausted, and the contradiction between supply and demand in the market has become increasingly serious. In order to alleviate the pressure on resources and the contradiction between supply and demand in the market, it is imminent to carry out the artificial planting of Fritillaria sichuanensis, but most of the source species of Friti...
