2-3 days before sowing, choose sunny noon to evenly spread the grains on the ground and sow the seed one day before sowing to “three wash and one stuffy mixâ€, that is, use the clean water to rinse the seeds first, and then use 10% salt water. Drain the full grain and wash the salt with clean water; select the good seeds with 0.1% of the amount of phosphorus pesticides, such as phoxim, to control the soil pests; and use 0.2%-0.3% of the seeds. The Rhizoctonia solani, Jinmanli or carbendazim and other seed dressings prevent white incidence and smut; after dressing, they can be sowed for 6-12 hours.
