Sunburn. Before seed soaking rice seeds, it is necessary to choose 2-3 days in sunny weather to improve the germination potential and germination rate of rice seeds. But be careful not to spread the rice seeds on the concrete floor or slate to prevent sunburning the seeds. Pay attention to flipping during the drying process.

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

Seed disinfection and soaking. The selected seeds were treated with 25% Shigak (microbamide) in a bag (10 mg) for 50 kg of water, soaked in 40 kg, the water temperature was maintained at 11-12 ° C, and the seeds were sterilized for 6 to 7 days. Note that when soaking seeds, the water should be 10 cm higher than the rice seeds, and the accumulated temperature should reach 100 degrees, turning once a day.

Promote germination. Remove the soaked seeds and use a gauze bag to germination. After the rice seeds are warmed up, the temperature is controlled at 30 to 32 °C. If the temperature is too high, the temperature should be turned over. After the whitening is broken, the temperature is controlled at 25 °C. When germination, it is necessary to pay attention to the change of rice temperature at any time. It is suitable for germination and germination. The length of the bud root should be within 2 mm. After urging it, bud in the shade and wait for sowing.
