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 ridges were raised according to the width of 1.2m, the height of the ridges was 30cm, and the distance between the ridges was 35cm. The seed collection area was 2 acres, and the grass-proof cloth was laid on April 22 to start collecting seeds, and it ended on May 15. to 0.85kg of seeds.

[0039] Implementation column 2

[0040] In August 2019, a gentle slope land in Yantian Town, Anfu County was selected, with a slope of about 10°, and the ground was plowed at a depth of 25cm; then the slope land was divided into two evenly, one with 1t / mu of organic fertilizer and 2t / mu of chaff Sprinkle the ash evenly on the soil surface, and rotate it once, without fertilizing one piece; Ridge according to the width of 1.2m, the height of the ridge is 25-30cm, preferably about 30cm, and the distance between the ridges is 35-40cm; start to treat the seeds in early September, Seed is the seed that embodiment 1 collects, and seed treatment has adopted 3 kinds of mo...

Embodiment 3

[0044] Lay grass-proof cloth on April 12, 2020. The shape of the grass-proof cloth is square, with a side length of 40cm. The opening is cut along the diagonal to the center. The seed collection will end on May 27, and a batch of newly matured seeds will be collected. For velvet grass seeds, prepare 6 concentrations of gibberellin solutions in the laboratory: T1, 0mg / L; T2, 50mg / L; T3, 100mg / L; T4, 150mg / L; T5, 200mg / L; T6 , 250mg / L, newly harvested velvet grass seeds were soaked in these solutions for 48 hours respectively, and placed in a petri dish (50 grains per dish) covered with double-layer filter paper, each treatment was repeated 3 times, at 25 ℃ temperature Accelerate germination, count the number of germinated seeds every day, until no longer increase, calculate the final germination rate, the results are shown in Table 2. The results showed that soaking seeds with gibberellin concentrations in the range of 100-200 mg / L could significantly increase the germination r...

Embodiment 4

[0048] Using the same batch of velvet grass seeds collected in May 2020 in the same batch as Example 3, a gibberellin concentration of 150mg / L was prepared in the laboratory, and the newly harvested velvet grass seeds were soaked in the gibberellin solution for 6h and 12h respectively , 24h, 48h, and 72h, placed in a petri dish covered with double-layer filter paper (50 grains per dish), each treatment was repeated 3 times, accelerated germination at a temperature of 25°C, counted the number of germinated seeds every day, until no longer increased, Calculate the final germination rate, and the results are shown in Table 3. The results showed that the germination rate was the highest when the soaking time was 24-48 hours.

Abstract

The invention belongs to the technical field of cultivation of medicinal plant seedlings, and relates to a large-scale seedling cultivation method for Monochasma savatieri Franch. ex Maxim. The large-scale seedling cultivation method for Monochasma savatieri Franch. ex Maxim. comprises the steps of seed collection, nursery land selection, plowing and fertilization, seed pretreatment, sowing and seedling management. The seed collection is conducted by using weed-proof cloth, and the weed-proof cloth surrounds a portion under Monochasma savatieri Franch. ex Maxim.; the seed pretreatment comprises the step of soaking seeds by using gibberellin. According to the large-scale seedling cultivation method for Monochasma savatieri Franch. ex Maxim., the weed-proof cloth is used for collecting the seeds, and the problem that the seeds of Monochasma savatieri Franch. ex Maxim. are difficult to collect is solved; and the gibberellin is used for pretreatment, seed dormancy is broken, and the germination rate is increased. The large-scale seedling cultivation method for Monochasma savatieri Franch. ex Maxim. is high in germination rate, easy to operate and convenient to popularize, and has a great promotion effect on protection of wild resources and development of the industry.

Description

technical field [0001] 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. Background technique [0002] Deer antler grass, also known as wool velvet grass, also referred to as velvet grass. Antler grass is a perennial herb belonging to the genus Scrophulariaceae. The whole herb is used as medicine. It has the functions of clearing heat and detoxifying, expelling wind and relieving pain, cooling blood and stopping bleeding. It is mainly used for cough, vomiting blood, red dysentery, leukorrhea, gingivitis, mastitis, boils Treatment of diseases such as swelling. Antler grass is mainly distributed in Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei and other places. It is difficult to meet the demand of domestic pharmaceutical production by digging wild resources, and a large number of wild velvet grass has made the natural distribution and growth supply of vel...
