How to improve the germination rate of Rice Seeds

Rice is a very important staple food in our country, and almost every meal is inseparable from rice in many places. Therefore, we can see the status of rice in China, and rice is also the most widely planted food crop in China. However, some problems are often encountered when growing rice, and the low germination rate of rice seeds is one of them. So how can we improve the germination rate of rice seeds when we plant rice? Let's take a look at it.

1. Seed drying

Put the seeds in the sun for about two days before sowing. It can effectively reduce the thickness of seed coat, promote the activity of enzymes, and significantly improve the germination rate of seeds. Many friends after the purchase of seeds due to poor management, resulting in a decline in the ability of seed germination, so seed drying is very important. And properly drying seeds can effectively reduce the substances that inhibit germination in the seeds. And it can dry the moisture in the seeds, facilitate the uniform distribution of water in the later stage of seed drying, and achieve the effect of disinfection and sterilization.

2. Seed soaking and disinfection

The purpose of seed soaking is to promote the water absorption of seeds, to ensure that each seed has sufficient water for germination, and to improve the uniformity of germination. First, soak the seeds in warm water for about a week. Then use chemicals for seed dressing and disinfection, although drying seeds can play a germicidal effect, but sterilization is not comprehensive. Therefore, in order to completely eliminate the germs in the seeds, we have to mix the seeds with prochloraz and other agents. Can effectively prevent evil seedling disease and other diseases, we should also choose the corresponding seed dressing agents according to the specific diseases we want to prevent and cure.

3. Moisturizing and budding

After doing a good job of seed soaking and disinfection, we also have to carry out the work of accelerating germination. In the budding must maintain a certain degree of humidity, humidity is also a lot of friends in the budding when the most easy to ignore the problem, resulting in the budding effect is not good. After soaking the seeds, air-dry the seeds, then wrap them in a wet cloth to promote germination. If the temperature is low, then we should also do a good job of heat preservation. When soaking seeds, the temperature should be controlled, and it should not be too high, otherwise it is easy to cause seeds to sprout and lose their ability to germinate.

4. Spread the buds equally

After the successful germination, in order to make the seeds adapt to the natural environment such as planting temperature, we need to dry the seeds again. The main purpose of this drying is to enhance the adaptability of the buds. Usually after sprouting, the seeds are spread out and dried indoors for about 12 hours before sowing. If some rice seeds cannot be sown in time because of low temperature and other environmental factors after budding. It is also necessary to sun the sprouts in time, control the growth of root buds by reducing the temperature and humidity, and then wait until the environment is suitable before sowing.

The above is a brief introduction to how to improve the germination rate of rice seeds. The germination of rice seeds is very important, which not only affects the growth ability of rice, but also has a direct relationship with the yield. That's all for today's introduction.
