Seed soaking and germination accelerating method for rice seeds

1. Before soaking rice seeds, it is generally necessary to choose sunny days for 2-3 days to reduce germs and improve the germination potential and germination rate of seeds. But you can't bask in the cement floor or slate to avoid sunburn and affect germination. Pay attention to turning frequently when drying, so as to dry evenly.

2. At the same time, pay attention to seed selection. After removing impurities such as chaff and broken grains from seeds, you can also select seeds with clear water, remove chaff floating on the surface, select full rice seeds, and cultivate neat and strong seedlings.

3. Seeds are not easy to soak for a long time. It is best to use the method of "soaking seeds during the day and exposing the ground at night", that is, soak the seeds with flowing clear water for 6 hours first (if there is no flowing clear water, change the water every 4-6 hours), and eliminate the old (old) seeds and soak them directly for 48 hours.

4. After the soaked seeds are drained until no water drops fall, the seeds can germinate, and the seeds can be wrapped with water to keep warm and moist. In the process of germination, we should always pay attention to the temperature change of seeds. Generally, the temperature should not be too hot to avoid the temperature of seeds being too high or too low. If the temperature is too high, the seeds should be sown in time to cool down, and if the temperature is too low, the seeds should be kept warm or heated externally.

5. The practice of sprouting Before sowing, spread out the seeds that have sprouted and germinated, and then sow after sprouting for 3-6 hours at room temperature. Make the grain seeds adapt to the temperature and improve the seedling rate.

6. After the seeds are exposed, adjust the temperature to 25 ~ 30℃ and accelerate germination and rooting at a suitable temperature. When the bud is half a grain long and the root length is 1 grain, it can be sown in the field, and the seedling length of mechanical transplanting and throwing seedlings should be shorter. In order to do a good job of soaking rice seeds and accelerating germination, it is necessary to turn 1-2 times a day to make the temperature of seeds uniform and consistent, so as to achieve orderly germination. In addition, proper water supply and ventilation should be paid attention to after chest rupture, so as to promote the buds to grow strong and well.
