Rice production is about to enter the sowing and nursery season. Scientific understanding of the time and method of soaking seeds is the key to raising the germination rate of rice and cultivating the strong and strong. Therefore, the majority of rice farmers should do the following processing before the broadcast of rice seeds:

Shaizhong. Before soaking rice seed, it is necessary to select good weather for 2-3 days so as to improve the germination potential and germination rate of rice seeds. But be careful not to spread rice seeds on the cement floor or slate to prevent sunburn. During the drying process, pay attention to turning.

Salt water selection. When selecting seeds, the proportion of brine should reach 1.13 (25 kg of water, 5 kg of salt dissolved). After the salt water is selected, it must be washed twice with clear water, otherwise the seeds will not sprout.

Seed disinfection and soaking. The selected seeds were used 25% scorcamine (10 mg) in a bag of 50 kg of water and soaked in 40 kg of water. The water temperature was maintained at 11-12°C and soaking for 6-7 days. Pay attention to soaking, the water should be more than 10 cm above the rice seed, the accumulated temperature should reach 100 degrees, turning once a day.

Germination. Remove the soaked seeds and use a gauze bag to germinate. After the rice seeds are warmed, the temperature is controlled at 30-32°C, and the temperature is too high to turn over. The temperature after dew-breaking is controlled at 25°C. When germinating, pay attention to the changes of rice seed temperature at any time, appropriate temperature and germination, and the bud root length should be within 2 mm. It is advisable to dry the bud in the cool place after sowing and wait for sowing.
