Embodiment Construction

[0066] A method for preserving ginseng germplasm resources and breeding seeds and seedlings, the steps of which are as follows:

[0067] 1. Location selection

[0068] The fine-bred breeding area is selected in Tonghua at 125°10'-126°44' east longitude and 40°52'-43°3' north latitude. The surrounding forest coverage rate should reach more than 80%, and there should be no concentrated population within 500 meters. Points and any industrial enterprises, no air, water pollution sources of land plots to build solar greenhouses.

[0069] 2. Solar greenhouse structure

[0070] The semi-arch solar greenhouse has a structure of 70-80m in length, 7-8m in span, 3-4m in top width, and 3-3.5m in wall height. The walls are made of concrete; the doors are left on both sides, and rat-proof boards are placed.

[0071] 3. Bed soil matrix preparation

[0072] Select a large amount of litter in the forest that is rotten and degraded, fertile, loose, rich in humus, organic matter, and the soi...

Abstract

The invention provides a method for conserving radix ginseng germplasm resources and propagating seeds and seedlings. Excellent radix ginseng varieties or the germplasm resources can be planted in sunlight greenhouses in an isolation manner by the aid of the method. The technical method includes (1), selecting locations; (2), constructing the sunlight greenhouses; (3), preparing seedbed soil substrates; (4), turning, disinfecting and laying soil; (5), directionally arranging beds; (6), carrying out germination accelerating treatment on the seeds; (7), establishing germplasm resource propagation gardens; (8), carrying out seed sowing modes; (9), carrying out management in growth periods; (10), carrying out processes for propagating improved varieties; (11), controlling diseases and insect pests; (12), harvesting fruits and storing the seeds; (13), carrying out processes for lifting, collecting and storing the seedlings, and the like. The method has the advantages that the scientific method for protecting the radix ginseng germplasm resources and propagating the seeds and the seedlings is provided according to biological characteristics of radix ginseng, and material guarantee and technical support can be provided for conserving and innovatively utilizing the radix ginseng germplasm resources.

Description

technical field [0001] The invention relates to a method for breeding Chinese medicinal materials, namely a method for preserving ginseng germplasm resources and breeding seeds and seedlings. Background technique [0002] Ginseng ( Panaxginseng .C.A.Mey. ) Araliaceae Panax genus, my country’s ginseng breeding work has been going on for nearly 70 years since the 1950s. However, due to the backward evaluation of germplasm resources protection, and the low reproductive coefficient of ginseng seeds, it is difficult to multiply offspring, resulting in ginseng populations There are few good variation materials available for variety breeding, and the breeding work has been progressing slowly. Only through the research on the collection, introduction, preservation and evaluation of ginseng germplasm resources can we realize the preservation of pure and excellent ginseng germplasm resources in the true sense. The improvement of ginseng can only be achieved by studying more advanced...
