Embodiment 1

[0032] 1. Seed collection

[0033] ① time

[0034] From late March to early May,

[0035] ② Record the date of listing on the flowering plants every day,

[0036] ③ 7 days after flowering, use 30-35 mesh transparent gauze to sew a 35 cm x 35 cm bag, and put it on the inflorescence.

[0037] ④ When the seed coat of the seeds is yellowish brown, take back the bagging before the flower stems wither and fall, and ripen the seeds for 3-5 days. After the inflorescences are dry in the shade, shake the seeds out.

[0038] ⑤ Use an 8-mesh sieve to screen out larger impurities, and then use an 18-mesh sieve to get new species of spider incense for later use.

Embodiment 2

[0040] Seed constant temperature treatment

[0041] ① Routinely disinfect the new species of spider incense, soak in distilled water at 30°C for 6-12 hours,

[0042] ②Put it in a sterilized Petri dish (9 cm in diameter) with filter paper, add appropriate amount of distilled water to keep the filter paper and seeds moist, and seal it with a film.

[0043] ③ Place the sterilized culture dish in a constant temperature incubator for cultivation. The temperature set in the constant temperature incubator is 0°C-30°C, preferably 5°C-30°C, 20°C-25°C, 25°C. Each treatment was repeated 3 times, 100 grains per dish. Observe and record the germination of the seeds.

[0044] The processing results are shown in Table 1

[0045] temperature (°C) Germination rate(%) 0 0 5 4.9 10 13.4 15 17.2 20 19.8 25 20.5 30 12.6

[0046] It can be seen from Table 1 that under the constant temperature condition, the germination of the seeds of the spide...

Embodiment 3

[0048] Seed variable temperature treatment

[0049] Set up 12 variable temperature treatments, each treatment has 3 repetitions, and 100 grains per dish. Observe and record the germination of the seeds.

[0050] ① Routinely disinfect the new species of spider incense, put them in the freezer at -5°C, -10°C or -15°C for 7 days, 14 days, 21 days and 28 days respectively,

[0051] ② Take out the seeds and soak them in distilled water at 30°C for 6-12 hours.

[0052] ③ Place in a sterilized Petri dish (9 cm in diameter) with filter paper, add appropriate amount of distilled water to keep the filter paper and seeds moist, and seal with a film.

[0053] ④ Place the sterilized culture dish in a constant temperature incubator at 25°C for cultivation.

[0054] The processing results are shown in Table 2

[0055] variable temperature treatment Germination rate(%) -15°C treatment for 7 days +25°C 45.4 -15℃ for 14 days +25℃ 50.7 -15°C treatment for 21 days...

Abstract

The invention discloses a method for improving the germination rate of the spider incense. The method comprises: collecting seeds and treating the seeds. Seed collection is a 35 cm x 35 cm bag sewn with 30-35 mesh transparent gauze, and the suit is realized on the inflorescence. Seed treatment includes constant temperature treatment and variable temperature treatment. For constant temperature treatment, the sterilized culture dish is placed in a constant temperature incubator for cultivation, and the temperature set in the constant temperature incubator is 25°C. During the temperature-changing treatment of the seeds, the new species of S. chinensis were sterilized routinely, and placed in a ‑10°C freezer for 21 or 28 days. The invention has the advantages of low cost and simple operation, effectively solves the problems of difficult collection and low germination rate of spider incense seeds in the natural environment, and provides technical basis for large-area artificial planting.

Description

technical field [0001] The invention belongs to the technical field of cultivation of medicinal materials, and in particular relates to a method for increasing the germination rate of spider incense. Background technique [0002] Spider incense (Valeriana jatamansi Jones) is a plant of the genus Valeriana in the Patella family, with aliases: horseshoe incense, even vanilla, blood lotus, black ginseng, etc. The roots and rhizomes of valeriana cordifolia contain 1,2-diketone substances, which can be obtained from isovaleric acid and caproic acid after alkali hydrolysis or acid hydrolysis, and also contain valerian glycoside isovalerate and valerian ring fenmelin. The rhizome is used as medicine and is a kind of precious Chinese medicinal material. It has the effects of regulating qi and relieving pain, digesting food and qi, invigorating the stomach and stopping diarrhea, expelling wind and dampness, calming the nerves and so on. In recent years, the regeneration ability of ...
