Embodiment 1

[0028] A method for rapid germination of poinciana seeds, comprising the following steps:

[0029] 1) Select fine mature seeds (Jiangxi seeds) with plump seeds and no pests and diseases. After removing impurities, wash the seeds with tap water 2 to 3 times to remove surface dirt.

[0030] 2) Place the cleaned seeds in an anti-corrosion glass container, slowly pour 98% concentrated sulfuric acid treatment solution into the glass container in a fume hood, submerge half of the seeds, and place them for 5 hours, during which time, use a glass container every half an hour. Stick stir 1 time. This operation requires the operator to wear anti-corrosion gloves, work clothes, and a mask, and the glass rod must be stirred slowly to prevent the liquid from splashing.

[0031] 3) After the treatment, the 98% concentrated sulfuric acid treatment solution should be slowly poured into another glass container, and the seeds should be rinsed with tap water for 8-10 times, and the seeds can al...

Embodiment 2

[0036] A method for rapid germination of poinciana seeds, comprising the following steps:

[0037] 1) Select fine mature seeds (Jiangxi seeds) with plump seeds and no pests and diseases. After removing impurities, wash the seeds with tap water 2 to 3 times to remove surface dirt.

[0038] 2) Place the cleaned seeds in an anti-corrosion glass container, slowly pour 98% concentrated sulfuric acid treatment solution into the glass container, submerge the seeds, and place for 5 hours, stirring once with a glass rod every half hour during this period.

[0039] 3) Slowly pour out the concentrated sulfuric acid treatment solution, scrub the seeds with tap water for 8-10 times, or rinse the seeds with flowing tap water for 5 minutes to remove the acid solution on the surface.

[0040] 4) Soak the treated seeds in clean water for 24 hours, take them out and place them in a germination box filled with 2 layers of moist filter paper, place them in an incubator at 25°C to 27°C, wash the s...

Embodiment 3

[0043] A method (Hainan seeds) for rapid germination of poinniana seeds, comprising the following steps:

[0044] 1) Select good mature seeds with plump seeds and no pests and diseases. After removing impurities, wash the seeds with tap water for 2 to 3 times to remove the dirt on the surface.

[0045] 2) Place the cleaned seeds in an anti-corrosion glass container, slowly pour 98% concentrated sulfuric acid treatment solution into the glass container, submerge the seeds, and place for 5 hours, stirring once with a glass rod every half hour during this period.

[0046] 3) Pour out the 98% concentrated sulfuric acid treatment solution slowly, and rinse the seeds with tap water 8-10 times to remove the acid solution on the surface.

[0047] 4) Soak the treated seeds in clean water for 24 hours, take them out and put them in a germination box filled with 2 layers of moist filter paper, place them in an incubator at 25°C to 27°C, wash the seeds with tap water once a day, and after...

Abstract

The invention discloses a method for quickly sprouting flame tree seeds, which includes the following steps: (1) selecting excellent mature seeds with full seeds and no diseases and pests, and cleaning the seeds after impurity removal; (2) placing the cleaned seeds in an anti-corrosive glass container, and soaking the seeds with an acid treatment solution; (3) washing the seeds with tap water formultiple times after acid etching to remove the acid solution on the surface, and then soaking overnight; (4) placing the soaked seeds in a sprouting box, placing the soaked seeds in an incubator at 25-27 DEG C for sprouting, and sprouting for 5-7 days; and (5) sowing the sprouted seeds on a seedling raising disc or a field seedbed for seedling cultivation. The method can obviously improve the germination rate, the germination potential and the emergence rate of the flame tree seeds, obviously improve the quality of seedlings, reach the highest germination rate of 94%, shorten the germinationtime to 7 days, and solve the difficulties of hard seed coat, long germination time, easy mold growth and low germination rate of the flame tree seeds.

Description

technical field [0001] The invention relates to the technical field of plant seed germination, in particular to a method for rapid germination of poinciana seeds. Background technique [0002] Phoenix wood (Delonix regia Raf.), also known as Phoenix flower, red flower jacaranda, fire tree, etc., is a leguminous plant. Native to Madagascar and tropical Africa, it is a large deciduous tree with a height of up to 20m. The tree shape is elegant and beautiful, with two pinnate compound leaves; the flowers are large, 7-10cm in diameter, the corolla is bright red to orange red, and the flowering period can last as long as For several months, the pods are flat and woody, 30-60 cm long, and each pod contains 10-20 seeds. Therefore, Phoenixwood has become one of the main greening tree species in southern subtropical regions such as Hainan, Guangdong, and Guangxi in my country. However, the outer layer of the poinciana seed coat is covered with hard colloid, which is hard, not easy t...
