1. Strengthen the closure and thermal insulation of warehouses, prevent the damage of insects, rats and finches, reduce the heat sources in the warehouse, delay the aging of food, and reduce food losses. 2. Strengthen the roof transformation of the warehouse, and increase the asbestos roof insulation and leakproof double roof. Due to the long-term high temperature and freezing effects of the two felt and three oil leakproof layers, they can easily deteriorate and fall off, causing irregular leakage of the warehouse. Inflict adverse effects on grain reserves. In addition, there is no roof insulation layer, grain surface space is easy to accumulate heat and accelerate the increase of grain temperature, resulting in changes in grain quality and moisture reduction. 3, minimize the use of chlorination library fumigation. Because chloropicrin will not only affect the quality of food and reduce the germination rate of food, but also chloropicrin can damage sack fiber. When the temperature and humidity are high, it will reduce the firmness of cotton and linen fabric, damage the packaging, and increase the cost of grain storage. 4, to strengthen the daily rainy weather warehouse leakage work, control the humidity inside the warehouse to prevent the local mildew of food. 5. Use "two-low" storage with five sides to reduce the evaporation of food moisture to facilitate fumigation and insecticide and food preservation. 6, strictly enforce the "three, seven" test method, monthly testing of food moisture and other quality, grasp the law of changes in grain conditions, and take appropriate measures in a timely manner. 7. Ventilate in time in autumn and winter to reduce grain temperature and ensure the safety of stored grain. 8. Put good food into storage and do a good job of preventing moisture at the bottom of grain storage. 9. It is advisable for the warehouse to be converted into a standard house type warehouse. Although the one-time input cost is relatively large, it only takes 4 to 5 years to recover the cost from the aspect of reducing the cost of food storage and ensure the quality of stored grain.
