Problems solved by technology

[0003] The germination rate of traditional cotoneaster seed germination method is low, the seed dormancy period is long (gather and sow directly in that year, and just can emerge in the 3rd year), therefore, need to develop a kind of germination method of cotoneaster seed with high germination rate

Embodiment 1

[0029] The low-temperature stratification germination-promoting method of the cotoneaster seed of the present embodiment comprises the following steps:

[0030] First prepare the prepared cotoneaster seeds: crush the mature cotoneaster fruits, put them into a sieve with an aperture of 0.30cm, rinse them repeatedly under running water, pour the sieved jam and seed mixture into Wash repeatedly in a fine sieve with an aperture of 0.15 cm, place the remaining mixture in the fine sieve in a ventilated and dry place to dry in the shade, rub repeatedly to remove impurities, and obtain the prepared Cotoneaster chuankang seeds; the prepared seeds have no Impurities are convenient for subsequent germination of seeds;

[0031] S1. Add hot water at a temperature of 100°C to the prepared Cotoneaster chuankang seeds while stirring. After stirring evenly, soak the seeds for 24 hours, then pour off the soaking water, and then add hot water at 100°C to the seeds and stir Evenly, then pour off...

Embodiment 2

[0063] The low-temperature stratification germination-promoting method of the cotoneaster seed of the present embodiment comprises the following steps:

[0064] First prepare the prepared cotoneaster seeds: crush the mature cotoneaster fruits, put them into a sieve with an aperture of 0.50cm, rinse them repeatedly under running water, pour the sieved jam and seed mixture Wash repeatedly in a fine sieve with an aperture of 0.20 cm, place the remaining mixture in the fine sieve in a ventilated and dry place to dry in the shade, rub again and again to remove impurities, and obtain the prepared Cotoneaster chuankang seeds.

[0065] S1. Stir while adding hot water at a temperature of 100°C to the prepared Cotoneaster chuankang seeds. After stirring evenly, soak the seeds for 24 hours, then pour out the water for soaking the seeds, and then add hot water at 100°C to the seeds. Stir evenly, then pour out the soaking water after soaking the seeds for 24 hours, then soak and disinfect ...

Embodiment 3

[0070] The low-temperature stratification germination-promoting method of the cotoneaster seed of the present embodiment comprises the following steps:

[0071] First prepare the prepared cotoneaster seeds: crush the mature cotoneaster fruits, put them into a sieve with an aperture of 0.50cm, rinse them repeatedly under running water, pour the sieved jam and seed mixture Wash repeatedly in a fine sieve with an aperture of 0.17 cm, place the remaining mixture in the fine sieve in a ventilated and dry place to dry in the shade, rub repeatedly to remove impurities, and obtain the prepared Cotoneaster chuankang seeds.

[0072] S1. Stir while adding hot water at a temperature of 100°C to the prepared Cotoneaster chuankang seeds. After stirring evenly, soak the seeds for 24 hours, then pour out the water for soaking the seeds, and then add hot water at 100°C to the seeds. Stir evenly, then pour out the soaking water after soaking the seeds for 24 hours, then soak and disinfect the s...

Abstract

The invention provides a low-temperature stratification germination accelerating method for cotoneaster ambiguus seeds. The method comprises the following steps: adding hot water at 100 DEG C into the prepared cotoneaster ambiguus seeds while stirring, soaking the seeds for 24 hours after uniformly stirring, then pouring away the water for soaking the seeds, repeating the steps again, then soaking and disinfecting the seeds for 2 hours by using a potassium permanganate solution, and finally, washing the seeds with clear water until the seeds are colorless to obtain treated seeds; putting the treated seeds into a net bag, placing the net bag filled with the treated seeds and disinfected wet river sand in a layered manner, then carrying out sand storage for 120 days at the temperature of 2 DEG C, then carrying out freezing storage for 30 days at the temperature of subzero 15 DEG C, then, carrying out standing for 30 days at the temperature of 15 DEG C, and finally, carrying out standing for 150 days at the temperature of 25 DEG C to complete germination accelerating of the cotoneaster ambiguus seeds. According to the method, the germination rate of the cotoneaster ambiguus seeds can be obviously increased through the steps of two-time seed scalding, variable-temperature sand storage and the like.

Description

technical field [0001] The invention belongs to the technical field of germination acceleration of seeds, and in particular relates to a low-temperature stratification acceleration germination method of Cotoneaster chuankang seeds. Background technique [0002] Chuankang Cotoneaster (scientific name: Cotoneaster ambiguus Rehd.et Wils.) is a plant of the genus Cotoneaster ambiguus Rehd.et Wils. in the Rosaceae family. It is a deciduous shrub up to 2 meters high. Falling glabrous or nearly glabrous, endemic to China; leaf blade elliptic-ovate to diamond-shaped-ovate, 2.5-6 cm long, 1.5-3 cm wide, apex acuminate to acute, base broadly cuneate, margin entire, above Sparsely pilose when young, shed soon, pilose below, sparsely pilose when old; petiole 2-5mm long, slightly pilose; stipules linear-lanceolate, mostly glabrescent, sparsely pilose hair. Cymes with 5-10 flowers, total pedicel and pedicel sparsely pilose; bracts lanceolate, slightly pilose, caducous; pedicels 4-5 mm l...
