Embodiment 1

[0017] After drying the seeds first, winnow the plump seeds. Then refer to the attached figure 1 Install the air supply equipment, put the air stone 3 through the mesh layer 2 into the bottom of the soaking basin, connect the air pump 5 through the rubber hose 4, then spread the seeds on the isolation board of the soaking basin, and add clear water in the soaking basin (add soaking seeds in clear water) Liquid agent), make it spread over the seeds 5cm.

[0018] Then put the soaking pot into the constant temperature room, open the ventilation equipment for 5 minutes, and close it for 10 minutes. The temperature is controlled at 25°C 24 hours before the soaking and germination process; The hourly temperature was adjusted to 26°C constant temperature for germination.

Embodiment 2

[0020] After drying the seeds first, winnow the plump seeds. Then refer to the attached figure 1 Install the air supply equipment, put the air stone 3 through the mesh layer 2 into the bottom of the soaking basin, connect the air pump 5 through the rubber hose 4, then spread the seeds on the isolation board of the soaking basin, and add clear water in the soaking basin (add soaking seeds in clear water) Liquid medicine agent), make it spread over the seeds 7cm.

[0021] Then put the soaking pot into the constant temperature room, turn on the ventilation equipment for 7 minutes, and turn off the ventilation for 10 minutes. The temperature is controlled at 25°C for 48 hours before the soaking and germination process; the temperature is adjusted to 32°C for the next 36 hours until the seeds are broken. For 24 hours, the temperature was adjusted to a constant temperature of 26°C for germination.

Embodiment 3

[0023] After drying the seeds first, winnow the plump seeds. Then refer to the attached figure 1 Install the air supply equipment, put the air stone 3 through the mesh layer 2 into the bottom of the soaking basin, connect the air pump 5 through the rubber hose 4, then spread the seeds on the isolation board of the soaking basin, and add clear water in the soaking basin (add soaking seeds in clear water) Liquid medicine), make it spread over the seeds 10cm.

[0024] Then put the soaking pot into the constant temperature room, turn on the ventilation equipment for 10 minutes, and then turn it off for 10 minutes. The temperature is controlled at 25°C for 72 hours before the seed soaking and germination process; the temperature is adjusted to 32°C for the next 48 hours until the seeds are broken. For 24 hours, the temperature was adjusted to a constant temperature of 26°C for germination.

[0025] In above-mentioned embodiment, the aeration volume can be smaller when whole seed ...

Abstract

The invention belongs to the field of rice cultivation and discloses a seed ventilated soaking method in rice seed accelerating germination. The method comprises the following steps: soaking rice seeds in a seed soaking solution, introducing gases into the soaked rice seeds every 10 minutes for 5-10 minutes for ventilating, controlling the temperature to be 25 DEG C within 24-72 hours before the seed soaking and accelerating germination process, regulating the temperature to be 32 DEG C within the subsequent 24-48 hours, soaking the seeds under the condition of constant temperature until the seeds are broken and exposed, regulating the temperature to be 26 DEG C within the subsequent 24 hours for accelerating germination. According to the method, air is introduced into the bottom of the seed soaking solution in the seed soaking process, the oxygen content in the air in the soaking solution is guaranteed, and the problem that the water lacks of oxygen in the seed soaking process is solved. According to the method, the germination rate of rice seeds is 83.4 percent and is improved by 27 percent compared with the ventilation-free seed-soaking accelerating germination rate of 65.7, and the germination rate of the seeds is obviously improved. Moreover, the germination rate of the seeds is improved, the cost of the seeds can be saved, particularly the cost of hybrid rice seeds is saved, and the rice production is stabilized.

Description

technical field [0001] The invention belongs to the field of rice planting, and relates to a seed aeration and seed soaking method in rice seed germination acceleration. Background technique [0002] Rice seeds are soaked and germinated before sowing. The main purpose of seed soaking is to make the seeds absorb enough water, accelerate seed germination, and promote the consistency of seed germination. During the soaking process of rice seeds, medicaments are added to kill the pathogens carried by rice seeds. The conventional seed soaking method is to put the seeds in an impermeable container, add water and immerse the seeds in water for 2 to 6 days. In the process of seed soaking, it is necessary to change the water frequently and turn it more often to increase the oxygen content in the water; under the condition of high temperature, if the water is not changed in time, it is easy to cause the growth of seed microorganisms, cause the seeds to stink, and the seed germinatio...
