Problems solved by technology

[0003] During the planting process of Asparagus bamboo, it is mainly to carry out branch propagation and seed propagation. In the traditional seed propagation process, the seeds are germinated by sand storage before sowing. It takes 25-40 days for the germination to germinate. The efficiency is too low, and there are no special literature and patent documents to report the germination method of Asparagus asparagus seeds

Embodiment 1

[0017] A method for accelerating germination of asparagus asparagus seeds, comprising the following steps:

[0018] (1) Soaking and softening: Select mature, complete and plump Asparagus asparagus seeds, soak them in 11% acetic acid solution at 56~58°C for 30 minutes, then ultrasonicate at 32kHz for 20 minutes to soften the seed coat and stimulate the germ Active, to speed up germination, to soak the seeds;

[0019] (2) Low-temperature fermentation: Add white sugar to the fermented seeds so that the mass fraction of white sugar is 6%, add Angel wine yeast, mix well, and ferment at 13°C for 7 days. The fermentation product can inhibit the activity of dormant substances and break down Seed dormancy, provide the nutrients needed for seed germination, kill residual germs, make the seeds germinate in advance, filter, and get fermented seeds;

[0020] (3) Peeling with temperature difference: freeze the fermented seeds at -23°C for 6 hours, take them out, and put them in a constant ...

Embodiment 2

[0027] A method for accelerating germination of asparagus asparagus seeds, comprising the following steps:

[0028] (1) Soaking and softening: Select mature, complete and plump Asparagus asparagus seeds, soak them in 12% acetic acid solution at 56~58°C for 33 minutes, then ultrasonicate at 33kHz for 23 minutes to soften the seed coat and stimulate the germ Active, to speed up germination, to soak the seeds;

[0029] (2) Low-temperature fermentation: Add white sugar to the fermented seeds so that the mass fraction of white sugar is 7%, add Angel wine yeast, mix well, and ferment at 14°C for 7 days. The fermentation product can inhibit the activity of dormant substances and break down Seed dormancy, provide the nutrients needed for seed germination, kill residual germs, make the seeds germinate in advance, filter, and get fermented seeds;

[0030] (3) Peeling with temperature difference: freeze the fermented seeds at -22°C for 7 hours, take them out, and place them in a constan...

Embodiment 3

[0037] A method for accelerating germination of asparagus asparagus seeds, comprising the following steps:

[0038] (1) Soaking and softening: Select mature, complete and plump Asparagus asparagus seeds, soak them in 13% acetic acid solution at 56~58°C for 35 minutes, then ultrasonicate at 34kHz for 25 minutes to soften the seed coat and stimulate the germ Active, to speed up germination, to soak the seeds;

[0039] (2) Low-temperature fermentation: Add white sugar to the fermented seeds so that the mass fraction of white sugar is 7%, add Angel wine yeast, mix well, and ferment at 15°C for 8 days. The fermentation product can inhibit the activity of dormant substances and break down Seed dormancy, provide the nutrients needed for seed germination, kill residual germs, make the seeds germinate in advance, filter, and get fermented seeds;

[0040] (3) Peeling with temperature difference: freeze the fermented seeds at -21°C for 8 hours, take them out, and place them in a constan...

Abstract

The invention discloses a germination accelerating method for the seeds of Asparagus setaceus, belonging to the technical field of plantation. The germination accelerating method comprises the following steps: soaking and softening; low-temperature fermentation; dehusking through temperature difference; and acceleration of seed germination. The method is simple, has a germination acceleration rate of 91%, and enables germination time to be shortened to 11 to 12 days, the survival rate of the seeds to reach 96% and economic income to be increased by 12.8%. According to the invention, the seeds of Asparagus setaceus are soaked with an acetic acid solution to soften seed coats, stimulate germ activity and accelerate germination; after low-temperature fermentation of the seeds, a fermentation product can inhibit the activity of dormancy substances, break dormancy of the seeds, provide the seeds with nutrients needed in seed germination and kill residual pathogens, so seed germination is brought forward; through temperature-difference treatment, the coats of the seeds of Asparagus setaceus have cracks, which facilitates entry of oxygen and nutrients and accelerates seed germination; and after the seeds are put in a germination accelerating box, germination acceleration conditions for the seeds are adjusted, germ activity is improved, stress resistance of germs is enhanced, and the survival rate of the seeds is increased.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for accelerating germination of asparagus asparagus seeds. Background technique [0002] Asparagus asparagus, also known as cloud pine, thorn asparagus, and cloud bamboo, has a beautiful shape, can relieve visual fatigue, purify sulfur dioxide, nitrogen dioxide, chlorine and other harmful gases, and can also secrete bacteria-killing gases to reduce colds, typhoid fever, The occurrence of infectious diseases such as laryngitis is of great benefit to human health and has a good ornamental value. The root can also be used as medicine to treat acute bronchitis, moisten the lungs and relieve cough. [0003] During the planting process of Asparagus bamboo, it is mainly to carry out branch propagation and seed propagation. In the traditional seed propagation process, the seeds are germinated by sand storage before sowing. It takes 25-40 days for the germination to germi...
