First, the choice of wheat seed wheat must be strictly before the harvest to the miscellaneous purification, the tall trees, small trees, dwarf trees, all cut ears, brought out of the field, leaving the wheat to single-single harvest to prevent mixing. Second, the storage method 1, anti-hygroscopic wheat strong hygroscopicity, red, hard wheat than white, soft wheat poor hygroscopicity. Wheat seeds with moisture content below 12% should be put into storage in time, and closed storage methods should be adopted to reduce the moisture absorption of the seed, maintain seed vigor for a long time, and have a high germination rate. When the water content is 13-14%, the seed temperature must be controlled below 25°C. When moisture content is 14-15%, the temperature is controlled below 20°C to prevent moisture absorption and ensure seed quality. When the moisture content exceeds 16%, it cannot be stored as seeds. 2. Storage methods Wheat is a conventional variety. Farmers can store a small amount of seeds in porcelain vats or woven bags. When storing with a porcelain urn, first put a certain amount of hay wood ash on the bottom of the cylinder, separate the seeds and ash with kraft paper, put the fully sun dried seeds into a porcelain vat, and cover the surface to prevent the seeds from absorbing moisture. When storing in woven bags, the moisture content of the seeds must fall below the safe moisture content of 12%, and should be kept away from the individual substances such as pesticides and chemical fertilizers, so as to prevent affecting the germination rate and vigor of the wheat seeds.
