Problems solved by technology

The primary problem of artificial planting is: how to provide excellent seedlings of Salvia miltiorrhiza to meet the production and quality requirements of Salvia miltiorrhiza
[0008] 2. Problems in breeding and raising seedlings
[0010] The flowering period of salvia miltiorrhiza is as long as 3 months, and the seeds of salvia miltiorrhiza are very small, with a thousand-grain weight of only about 1.2 grams, so the collection of salvia miltiorrhiza seeds is very time-consuming and labor-intensive
Simultaneously under natural conditions, the seeds of Salvia miltiorrhiza are not resistant to storage, and the germination rate is low. When the seeds of Salvia miltiorrhiza are stored dry at room temperature, the germination rate of the seeds will drop by 10% every 30 days. If the storage time exceeds half a year, the germination rate will be lower than 40%, which seriously affects the Artificial cultivation of Salvia miltiorrhiza

Embodiment 1

[0047] Embodiment 1: the purification of salvia miltiorrhiza

[0048] After the germplasm resources of Salvia miltiorrhiza are planted and evaluated, they are isolated and bagged in mesh bags to achieve self-pollination and firmness of a single plant; after the seeds of a single plant are harvested, they are individually dried, threshed, preserved, and seedling-raised. The strains after 3-4 times of selfing of individual plants are screened for quality, yield and ecological characteristics, and different individual plant populations are selected as the parent materials of the hybrid combination.

[0049] Among them, the code number of the female parent is 2010081-4 (fertile), which was collected, planted and identified by Mengyin Salvia miltiorrhiza in 2006. After four times of selfing and purification, the population performance is consistent. Its characteristics are: compact plant type, plant height of 40-55 cm in full flowering stage, 3-5 branches, oval, green leaves, 3 or 5 ...

Embodiment 2

[0053] Embodiment 2: hybrid ZJ20132006 breeding and seedling breeding.

[0054] The female parent code of the hybrid is 2010081-4 (fertile), and the male parent code is 2010166-1.

[0055] 1 Breeding of hybrid ZJ20132006

[0056] The female parent 2010081-4 (fertile) and the male parent 2010166-1 were planted in equal rows at a ratio of 1:1.

[0057] 1.1 Selection of breeding fields

[0058] Choose loamy plots with deep, loose, fertile, and well-drained soil in the area where there is no salvia plantation or wild salvia miltiorrhiza distributed within 5 kilometers around, and clay should be avoided.

[0059] 1.2 Fertilization for soil preparation

[0060] At the end of October, 2500 kg of farmyard manure and 15 kg of diammonium phosphate were applied per mu combined with land preparation. Implement unified mechanical tillage, deep loosen more than 30 cm, loosen the soil on the top and harden the soil; level off and rake finely. Drainage ditches with a width of 1.5 meters ...

Embodiment 3

[0093] Embodiment 3: hybrid ZJ20132011 breeding and seed production

[0094] The female parent code of the hybrid is 2010125-1 (male sterile), and the male parent code is 2010198-1.

[0095] 1 Hybrid breeding

[0096] 1.1 Breeding field selection

[0097] Choose loamy plots with deep, loose, fertile, and well-drained soil in the area where there is no salvia plantation or wild salvia miltiorrhiza distributed within 5 kilometers around, and clay should be avoided.

[0098] 1.2 Fertilization for soil preparation

[0099] At the end of October, 2500 kg of farmyard manure and 15 kg of diammonium phosphate or special fertilizer for Chinese herbal medicines were applied per mu. Implement unified mechanical tillage, deep loosen more than 30 cm, loosen the soil on the top and harden the soil; level off and rake finely. Drainage ditches with a width of 1.5 meters and a depth of 1 meter are built around Daejeon to connect the drainage facilities outside the base.

Abstract

The invention discloses a seed production and seedling raising method of new species of salvia miltiorrhiza. The seed production and seedling raising method is characterized in that a salviae miltiorrhiza inbred line is obtained by a measure of sleeving individual salviae miltiorrhizae with mesh bags for isolation and inbreeding and pollinating the salviae miltiorrhizae to seed, and the salviae miltiorrhiza inbred line is used as a breeding material for performing crossing (by two modes: female sterile crossing and female fertile reciprocal crossing) to obtain the new species. The new specieswith superior features is selected to perform in-situ seedling raising by a seed production and seedling raising integrated measure (planting the salviae miltiorrhiza breeding material on ridges and planting peanuts in seedling raising furrows for casting a shade for growth and development of salviae miltiorrhiza seeds) to obtain a big quantity of seedlings with superior features, thereby promoting development of the salviae miltiorrhiza industry.

Description

technical field [0001] The invention relates to a method for producing and raising seedlings of new varieties of salvia miltiorrhiza, belonging to the technical field of breeding of traditional Chinese medicinal materials. Background technique [0002] Salvia miltiorrhiza Bunge, scientific name: Salvia miltiorrhiza Bunge, is a perennial erect herb of the dicotyledon family Salvia genus, distributed in Anhui, Shanxi, Hebei, Sichuan, Jiangsu and other places in China. In addition, Hubei, Gansu, Liaoning, Shaanxi, Shandong, Zhejiang, Henan, Jiangxi and other places are also distributed. Salvia miltiorrhiza is a traditional Chinese medicinal material in my country. It uses its roots as medicine. It has the functions of removing blood stasis, promoting regeneration, promoting blood circulation, and regulating menstruation. It is an important medicine for gynecology. Coronary heart disease also has a good effect. [0003] The output of salvia miltiorrhiza mainly comes from the wi...
