Embodiment 1

[0018] Chinese Academy of Sciences South China Botanical Garden Antler Grass Planting Guangzhou Base.

[0019] The natural temperature for seed soaking and germination is between 20 and 35°C.

[0020] Take fresh velvet grass seeds, use 600μM gibberellin aqueous solution, soak for 24 hours under natural indoor light conditions, and then sprinkle the seed suspension on the surface of sandy red soil at a place two meters above the surface of the red soil. Cover a layer of shading net with a shading rate of 90%, and then water or spray moisture every day. The seed germination rate reaches 90% in half a month. After 2-3 months, the seeds germinate until the plants grow to a height of 10-20 cm. To meet the needs of raw materials for commercial production. In the process of planting and germination, organic fertilizers or chemical fertilizers can be used appropriately, which is beneficial to the growth of plants. After the growth of the plants tends to be stable, the light can be i...

Embodiment 2

[0022] Chinese Academy of Sciences South China Botanical Garden Antler Grass Planting Guangzhou Base.

[0023] The natural temperature for seed soaking and germination is between 20 and 35°C.

[0024] Take fresh velvet grass seeds, soak them in 50 μM gibberellin aqueous solution under natural light for 24 hours, then sprinkle the seed suspension on the surface of sandy red soil, and cover a layer two meters above the surface of the red soil. Layer a shading net with a shading rate of 90%, and then water or spray to moisturize every day. After half a month, the seed germination rate will reach 78%. After 2-3 months, the seeds will germinate until the plants grow to a height of 10-20 cm, basically reaching Raw material needs for commercial production.

Embodiment 3

[0026] Chinese Academy of Sciences South China Botanical Garden Antler Grass Planting Guangzhou Base.

[0027] The natural temperature for seed soaking and germination is between 20 and 35°C.

[0028] Take fresh velvet grass seeds, soak them in 3000 μM gibberellin aqueous solution under natural light for 24 hours, then sprinkle the seed suspension on the surface of sandy red soil, and cover a layer two meters above the surface of the red soil. Layer a shading net with a shading rate of 90%, and then water or spray to moisturize every day, and the seed germination rate will reach 64% in half a month. After 2-3 months, the seeds will germinate until the plants grow to a height of 10-20 cm, basically reaching the commercial level. Raw material needs for chemical production.

Abstract

The invention discloses a method for Monochasma sheareri Maxim.ex Franch.et Savat seed germination and seedling breeding. The method comprises the following steps: soaking Monochasma sheareri Maxim.ex Franch.et Savat seeds in 50-3000 muM gibberellin for 24-48 hours, wherein the soaking process is performed in natural lighting; broadcast-sowing the soaked seeds on a surface of sand-containing red earth, covering a layer of a shading net above the red earth, watering or spraying for moisture retention; the germination temperature of the seeds is 20-35 DEG C. The Monochasma sheareri Maxim.ex Franch.et Savat seeds of the invention have a certain dormant period; by the combination of natural lighting (lighting is necessary for the gibberellin treatment and germination process, or germination is absolutely impossible) with gibberellin treatment, the invention completely breaks the dormancy; the germination rate for fresh seeds is up to above 90%; 2-4 months are taken for the seeds to grow into plants with a height of 10-20 cm from seed germination; no plant transplantation is needed; the survival rate is high; the method has the advantages of simplicity, convenience, rapidness and effectiveness; a lot of seedlings can be bred within a very short period, and raw materials required for medicine can be obtained.

Description

Technical field: [0001] The invention belongs to plant propagation technology, in particular to a method for seed germination and seedling cultivation of velvet grass. Background technique: [0002] Antler grass (Monochasma sheareri Maxim.ex Franch.et Savat) is a perennial herb belonging to the family Scrophulariaceae. Bitter in the mouth, cool in nature. It is used for the treatment of cough, hematemesis, red dysentery, leukorrhagia, gingivitis, mastitis, boils and other diseases. It is mainly distributed in Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei and other places. It is difficult to meet the needs of domestic pharmaceutical production by mining wild resources, and the natural distribution and growth supply of velvet grass is becoming less and less. Therefore be badly in need of seeking a kind of breeding method of artificial cultivation. At present, there are no patents and research reports on the propagation technology of velvet grass seedlings in China. ...
