1. Sunning: One week before soaking, choose a sunny day to sun the seeds for 6-8 hours, and then put the sunned seeds in a dry and cool place to cool the heart. 2. Seed selection: It is required to select seeds with clear water, fish out the blighted grains floating on the surface, and select full rice seeds.

1, drying seedOne week before soaking, sun the seeds for 6-8 hours on a sunny day, and then put the sun-dried seeds in a dry and cool place to cool through the heart.
2. Selection of seed: It is required to select seeds with clear water, fish out the chaff grains floating on the surface, and select full rice seeds.
3. Promote seed soaking with living water: The soaking time is not easy to be too long. It is better to adopt the method of "daily soaking and night dew", I .e. soaking seeds during the day and taking out and spreading them at night. When soaking seeds, it is better to immerse seeds in flowing clear water for 6 hours (if there is no flowing clear water, the water should be changed every 4-6 hours or so).
4. Advocate drug soaking seedThe commonly used medicine is 25% prochloraz 2000-3000 times (I .e. 2ml mixed with 5kg of water and 4-5kg of seed soaking) for 6 hours. The disinfectant should be one inch higher than the surface of the seed (no water change during disinfection), and then the rice seeds should be rinsed repeatedly with clean water to rinse the residual liquid.
5. GerminateAt present, there are still many farmers who like to put seeds in woven bags to promote germination. Even if the temperature does not rise, the seeds are exposed to the sun, which often causes germination. The best and simplest method is to use double-layer, disease-free, moist sacks to promote germination, pad a layer of disease-free straw on the ground, spread a sack, spread the seeds evenly on it, and then cover another sack on it. Only a little attention should be paid to whether to add water in the middle. Can also be loaded into sacks or relatively ventilated woven bags, around the available straw sealed insulation. After the grain is heated, the temperature is controlled at 35~38 ℃. If the temperature is too high, the pile will be turned over. If the temperature is too low, the warm water will be poured to raise the temperature. After about 20 hours, the grain can be exposed and broken. If the temperature is normal in mid-to-late May, the daily immersion and night dew method will be adopted without adding heat preservation materials, and the germination can be normal.
6, timely sowingAfter the grain is exposed to white, the temperature is adjusted to 25~30 ℃, the appropriate temperature is used to promote germination and root promotion, and the seed can be sown into the field when the bud grows half a grain of grain and the root grows one grain of grain.
7, refined budBefore sowing, spread out the sprouted grain seeds and refine the sprouts at normal temperature for 3-6 hours before sowing. Make the grain species adapt to the air temperature and improve the seedling rate.
