Problems solved by technology

Studies have found that it is difficult to cultivate velvet grass seedlings through cuttings and root divisions, which cannot meet the needs of large-scale production; the seeds of velvet grass are small and will fall off randomly after maturity. Moreover, the seed germination rate is low, only about 12.6%, and the effect of cultivating seedlings with seeds is not ideal; at present, the artificial breeding of velvet grass seedlings in China is mainly through tissue culture, which has high requirements for tissue culture technology and facilities. Requirements, and the survival rate of hardened seedlings of tissue cultured seedlings is not high, it is not easy to popularize and apply

Embodiment 1

[0038] In January 2019, the ridge is 30cm, the ridge distance is 35cm, and 2 acres of ridge is prepared, and the seeds are laid on April 22nd to collect seeds until the end of May 15th, the total collection To 0.85kg seed.

[0039] Implement 2

[0040] In August 2019, he selected a glimpse of Yancian Town, Anfu County, with a slope of approximately 10 °, flipped according to the depth of 25cm; then divided into two pieces in the slope, one piece according to 1T / min organic fertilizer and 2T / acres The gray is uniform, and the flour of the flour will be diled. One piece does not fertilize; according to 1.2m wide ridge, the ridge is 25 ~ 30cm, it is suitable for 30cm, the ridge spacing is 35 ~ 40cm; the seeds began to deal with seeds in early September, Seeds were seeded in Example 1, seed treatment using three ways: 1) water soaking seed, 2) 50 mg / L gibberellin solution soaking, 3) 150 mg / L gibberein solution is soaked; use the above manner to treat seeds After the treatment...

Embodiment 3

[0044] On April 12, 2020, the anti-strailling traits were square, and the side length was 40cm. The opening edge of the diagonal position was taken to the center of the center, and the seed collection ended on May 27, collecting a batch of mature The velvera seeds, configured 6 concentration gradients in the laboratory: T1, 0mg / L; T2, 50mg / L; T3, 100 mg / L; T4, 150mg / L; T6, 200mg / L; T6 250mg / L, new reserved dealer grass seeds were soaked in these solutions for 48 hours, placed in a culture dish with double-layered filter paper (50 capsules per dish), each treatment repeated 3 times, at 25 ° C temperature The germination, the number of germinated seeds per day until it is no longer increased, the final germination rate is calculated, and the results are shown in Table 2. The results show that the gibberellin concentration can significantly improve the germination rate in the range of 100 to 200 mg / L.

Embodiment 4

[0048] The original mature velvera seeds collected in May 20020 were used in May. In the laboratory, 150 mg / L gibberellin concentration was prepared, and the new velvet blast seed was soaked in a gibberellin solution 6h, 12h. 24h, 48h, 72h, placed in a culture dish with two-layer filter paper (50 capsules per dish), each treatment repeated 3 times, germination at 25 ° C, mass germination seeds per day until no more increased, The final germination rate is calculated, and the results are shown in Table 3. The results show that the sprocket rate is the highest when the soaking time is 24 ~ 48h.

Abstract

The invention belongs to the technical field of cultivation of medicinal plant seedlings, and relates to a method for large-scale cultivation of velvet antler grass. The method for large-scale seedling cultivation of Cervis antler grass provided by the present invention includes seed collection, selection of nursery plots, fertilization, seed pretreatment, sowing and seedling management; the seeds are collected using weed-proof cloth, and the The grass-proof cloth is surrounded directly below the velvet grass; the seed pretreatment includes using gibberellin to soak the seeds. The invention uses the grass-proof cloth to collect the seeds, which overcomes the problem of difficulty in collecting the velvet grass seeds; the gibberellin pretreatment breaks the dormancy of the seeds and increases the germination rate. The method for cultivating large-scale seedlings of velvet antler provided by the invention not only has a high germination rate, but also is simple to operate and easy to popularize, and has a great role in promoting the protection of wild resources and the development of industries.

Description

Technical field [0001] The present invention belongs to the cultivation of pharmaceutical plant seedling cultivation techniques, and involves a method of cultivation of Shatu velvettegraduated seedlings. Background technique [0002] Shada deer grass, also named lauder, also referred to as velvet. The velvet grass is a perennial plants in Xuanzhiku, the whole grass, the whole grass is used to add medicine, and the heat of hot and detoxification, hurricane and pain and blood hemostasis are mainly used for cough, vomiting blood, redish, banding, gingivitis, mastitis, 疖Treatment of diseases such as swollen. The velvet grass is mainly distributed in Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei and other places. By excavating wild resources difficult to meet the needs of domestic pharmaceutical production, a large number of excavation of wild antler leaves makes the natural distribution and growth supply of velvet. [0003] It is the only way to protect wild resources can also e...
