1, after the ripening time long wheat after the harvest has obvious after-ripening period, enhanced respiration, strong physiological metabolism, easy to heat, mildew, after the completion of ripening, can improve the quality of wheat, improve storage stability. Most of the wheat ripening period is 60 days, and a few more than 80 days. Generally, the germination rate reaches 80% as a sign of completion of ripening. 2. High-temperature-resistant wheat has strong heat-resistance. When the temperature is between 50-55°C, respiratory enzymes do not damage and proteins do not denature. Generally, the water content is less than 17% and the temperature does not exceed 54°C, which does not affect the seed germination rate. 3, easy to moisture absorption Wheat seed coat thin, no shell protection, soft tissue, strong water absorption, easy to breed pests, causing fever and mildew or sprouting. Storage method 1, hot pack, high temperature sealed use of wheat heat resistance, drying and storage in high temperature sunny days, can play a role in drying, promote ripening, insecticidal and bacteriostatic. Specific approach: 1 Select high temperature sunny weather sun cereals. The first sun dam, after the stalls drying wheat. Diluted and spread. 2 digging. The barley was sunned to 50°C for 2 hours to make the water content less than 12.5%. 3 bored heap insecticide. The spread wheat was piled into a small heap of 2,500 kg. It was hot and boring for half an hour, keeping the temperature of above 46°C. 4 cleaning and preheating. Before warehousing, warehouses, tools, and equipment should be cleaned, disinfected, and warmed up. 5 enthusiasm to warehousing inventory, promptly cover the closed, anti-moisture heat, pest recovery and other damage. Maintaining a temperature of 42°C for 10 days can kill pests, adults and their fleas and eggs. 2, control of water, maintain low temperature and low oxygen In order to long-term storage of wheat, improve the stability of the storage of grain, must control the moisture content of wheat, maintain low temperature and low oxygen state. For wheat with a moisture content of less than 12.5%, it can be stored in a sealed, moisture-proof manner and can be safely stored; if the temperature of the wheat with water content of 14%-15% rises to 22°C, it will be easily corrupted if poorly managed. For wheat that has been stored for one year to two years, heat is used for sealing and cold storage in winter to remove impurities. Dilution after cooling, cold storage, "cold sealed" storage, can prevent wheat deterioration, insects, mold, etc., to achieve the purpose of safe storage.
