How to Improve the Germination Rate of Rice Seeds? A Detailed Guide to the Latest Methods
Rice is a very important staple food crop in China, and in many places people can hardly go a single meal without rice. This shows the status of rice in China, and rice is also the grain crop with the widest planting area in the country. However, when growing rice, people often run into some problems, and a low germination rate of rice seeds is one of them. So when we grow rice, how should we improve the germination rate of rice seeds? Let's take a look below!
1. Sun-drying the seeds
Before sowing, put the seeds under the sun to bake for about two days. This can effectively reduce the thickness of the seed coat, promote enzyme activity, and noticeably improve the seed germination rate. Many friends find that after buying seeds, poor management causes the germination ability of the seeds to decline, so sun-drying the seeds is a very important task. Proper sun-drying can also effectively reduce the substances in the seeds that inhibit germination. It can also dry out the moisture inside the seeds, which helps promote even moisture distribution during later sun-drying, and can also achieve a disinfecting and sterilizing effect.
2. Soaking the seeds and disinfecting them
Soaking the seeds is meant to promote water absorption by the seeds, ensure that every seed has enough water for germination, and improve the uniformity of germination. First, put the seeds in warm water and soak them for about one week. Then use chemicals to dress the seeds and disinfect them. Although sun-drying the seeds can have a sterilizing effect, the sterilization is not complete. Therefore, in order to thoroughly eliminate the pathogens inside the seeds, we should dress the seeds with chemicals such as prochloraz. This can effectively prevent diseases such as bakanae disease, and we should also choose the corresponding seed-dressing chemical according to the specific disease we want to control.
3. Keeping moisture and promoting sprouting
After completing the soaking and disinfection work, we also need to promote sprouting. When promoting sprouting, a certain level of humidity must be maintained. Humidity is also the problem that many friends most easily overlook when promoting sprouting, which leads to poor sprouting results. After soaking the seeds, air-dry them, then wrap them in a wet cloth to promote sprouting. If the temperature is relatively low, then we also need to do a good job of keeping them warm. When soaking the seeds, the temperature should be controlled and should not be too high, otherwise it is easy to cause the seeds to burn their sprouts and lose their germination ability.

Spreading out the sprouts to dryAfter sprouting is successful, in order to let the seeds adapt well to the natural environment such as the planting temperature, we also need to dry the seeds again. This round of sun-drying is mainly to strengthen the adaptability of the sprouts. Usually after promoting sprouting, spread the seeds out indoors to air-dry for about 12 hours, and then sow them. If some rice seeds cannot be sown in time after sprouting due to environmental factors such as low temperature, they should also be dried in time. By lowering temperature and humidity, the growth of roots and sprouts can be controlled, and then they can be sown when the environment is suitable.
The above is a brief introduction to how to improve the germination rate of rice seeds. The work of promoting sprouting of rice seeds is very important, as it not only affects the growth ability of rice, but is also directly related to yield. That is all for today's introduction.
