Problems solved by technology

During the breeding process of celery, the seed germination rate is low, the germination is slow, and the germination is irregular, which has a great impact on production and increases the cost of planting
As far as the applicant knows, the seed itself is a very complex organism, and the reasons for the low germination rate of different seeds are also different. Clover seeds can be divided into dark brown, brown and yellow-gray according to the germination rate and color, among which dark brown The germination rate of the seeds is the highest, followed by the brown color, and the yellow-gray is the lowest. If you want to increase the germination rate of celery seeds, you usually use the color card to select dark brown seeds for breeding. The brown and yellow-gray seeds are discarded and are wasted.

Embodiment 1

[0021] Prepare saline with a mass concentration of 15%, benomyl at 500 times liquid, gibberellin solution at 250 mg / L, and naphthaleneacetic acid solution at 45 mg / L. Soak the celery seeds in 15% salt water for 10 minutes, and remove the floating sundries and deflated seeds, then wash the seeds with clean water, then put the washed celery seeds in 500 times liquid benomyl Soak in (benomyl weight unit 1: water weight unit 500) for 5 hours, remove and drain excess water, and then put the drained celery seeds in a concentration of 250mg / L at 25°C±2°C Soak in the gibberellin solution for 12±0.5 hours, wrap the celery seeds soaked in the gibberellin with gauze to prevent the seeds from scattering, and soak in warm water whose water temperature gradually drops from 55°C to 35°C for 6 hours. hours (at this time, the cooling rate of warm water is 3-3.6°C / hour). After soaking at variable temperature, spread the seeds evenly on the surface of the sponge block (germination requires ligh...

Embodiment 2

[0023] The difference between this example and Example 1 is that saline with a mass concentration of 18%, benomyl with 1000 times liquid, 300 mg / L gibberellin solution, and 20 mg / L indole acetic acid solution were prepared. After the clover seeds were soaked in saline with a mass concentration of 18% for 8 minutes, the clover seeds were soaked in 1000 times liquid benomyl (benomyl weight unit 1: water weight unit 1000) for 10 hours, and then Soak in 300mg / L gibberellin solution at 25±2°C for 11.5 hours, place the seeds in a breeding tray and add 20mg / L indole acetic acid to the breeding tray, accelerate germination under variable temperature conditions, and then observe And record the germination rate, germination potential and germination index of clover seeds in 7 days, and the fresh weight per plant, bud length and lateral root number of seedlings, and record it as treatment 2, the results are shown in Table 1.

Embodiment 3

[0025] The difference between this example and Example 1 is that saline with a mass concentration of 16%, benomyl with 700 times liquid, and 200 mg / L gibberellin solution were prepared. After soaking the clover seeds in saline with a mass concentration of 16% for 12 minutes, soak the clover seeds in 700 times liquid benomyl for 7 hours, and then soak them in 25±2°C at a concentration of 200mg / Soak in the gibberellin solution of L for 12.5 hours, seed is placed in the breeding dish and adds the gibberellin of 200mg / L to the breeding dish, vernalizes under variable temperature conditions, then observes and records the germination rate of celery seed in 7 days, The germination potential and germination index, as well as the fresh weight per plant, bud length and lateral root number of the seedlings were recorded as treatment 3, and the results are shown in Table 1.

Abstract

The invention relates to a method for enhancing the mitsuba seed germination rate, which comprises the following steps: soaking mitsuba seeds in salt water with the mass concentration of 15 to 18%, clearing floating dopants and shrivelled seeds, cleaning the seeds with clean water, soaking the mitsuba seeds cleaned by the clean water in benomyl of 500 to 1000 times, fishing out, and trickling moisture; soaking the trickled mitsuba seeds in gibberellin solution with the concentration of 150 to 300 mg / L for 11.5 to 12.5 hours at the temperature of 23 to 27 DEG C, then soaking in lukewarm water of which the water temperature falls from 55 DEG C to 35 DEG C gradually for 5.5 to 6.5 hours, placing the mitsuba seeds soaked by the lukewarm water in a breeding plate, and accelerating germination under a temperature alternating condition. The method takes certain process measure to the seeds before the sow to improve the germination rate and the sow quality of the seeds, is good to save the seed dose, meanwhile also promotes the initial grow of the germchit, and enhance the resistance of the plants.

Description

technical field [0001] The invention relates to a method for increasing the germination rate of plant seeds, in particular to a method for increasing the germination rate of celery seeds, and belongs to the technical field of agriculture and forestry. Background technique [0002] Clover celery (Cryptotaenia japonica Hassk.), also known as duck celery, mountain celery, wild Shu celery, etc., is a perennial herbaceous perennial plant of Umbelliferae and japonica Hassk. The whole plant can be used as medicine, and the tender stems can be eaten as vegetables. Every 100g edible part contains 1.1g of protein, 2.6g of sugar, VA100 international unit, VB10.04mg, VB20.02mg, calcium 44mg, phosphorus 38mg, iron 0.8g, so clover is very popular in the international market, Japan In countries such as South Korea and South Korea, the cultivation of celery is mainly through hydroponics, and the demand for seeds is very large. A large amount of celery seeds need to be imported from China e...
