I. Causes of seed fever 1. The seeds continue to breathe during storage, releasing moisture and heat one after another. If these moisture and calories cannot be distributed in time, the surface will accumulate in the seed piles, which will increase the respiration intensity of the seeds and release more moisture and calories. Such repeated and mutual promotion will take a long time and cause fever. 2. Due to the respiration of seeds, a large amount of moisture and heat accumulate in the seed heap, which is conducive to the growth and reproduction of microorganisms. In microbiological activities, more water and calories can be released, which is more likely to cause fever. 3. During seed storage, seed moisture absorption occurs due to poor storage conditions or improper management. The greater the seed moisture content, the stronger the respiration and the more moisture and heat released, which will result in seed fever. In addition, some pests, such as gluten, can also promote seed heating if they reproduce in large numbers. Second, prevention measures 1, the seed warehouse should choose high dry terrain, low groundwater level, Xiangyang leeward place, the warehouse must have a certain degree of moisture and heat insulation properties, that is, can be closed to maintain low temperature and dry, but also ventilation, anti-warm and loose. 2. The lower the seed moisture content, the weaker the respiration. Before storage of seeds, they should be fully air-dried, clean, and strictly tested so that their water content, cleanliness, etc., can reach the safe storage standards before they can be stored. If the weather is not good enough and there is no adequate drying, after the seeds are put into storage, strong ventilation should be carried out to reduce the moisture content of the seeds. 3, during the ripening of the seed, vigorous breathing. Therefore, before the seeds are stored in the storage, they should be fully air-dried so as to promote the subsequent ripening effect. In the early stage of storage, the seeds of crops with long ripening effect should be strongly ventilated to reduce the temperature and disperse moisture. 4. After the seeds are exposed to the sun, they should be adequately air-dried and cooled, and then stored in storage, so as to avoid excessively high seed temperature, enhanced breathing, or due to the large temperature difference between the warehouse and the seeds, and the phenomena of redistribution of water, causing the seeds to dampen and dampen. 5. During the storage of seeds, the temperature and humidity of the warehouse should be inspected. If there is an abnormal phenomenon, clear weather should be selected, timely ventilation, cooling and looseness, and identify the reasons, and take timely measures. 6. Seed temperature, moisture content and pests should also be inspected during seed storage. Abnormal phenomena should be taken promptly. Such as ventilation and ventilation, deep rake the surface of the seed piles, dumping, dumping, drying and impurity removal, etc., to reduce the tide. The use of methods such as exposure and freezing will worsen the living conditions of pests and microorganisms, as well as directly kill pests and microorganisms. If the insect pests are serious or difficult to turn over, they can be used for drying and can be controlled by aluminum phosphide or phosphine. 123 55 6ssw 123 55 6ssw Ganzhou Green days Biochemical Technology Co., Ltd. , http://www.cn-gangdao.com
