First, close the window Spring is the time when the cold and warm air flow meet each other, often due to a sudden drop in outside temperature, so that the surface of the seed pile "dew" occurs, that is, the surface of the seed is very humid, absorbs a lot of water vapor, and gradually condensed into tiny droplets. Seed condensation often leads to fever, mildew, and loss of seed. Therefore, when the cold wave arrives, warehouse doors and windows should be sealed to prevent a sudden drop in temperature inside the warehouse. Second, killing insects Spring temperatures gradually warmer, a variety of pests began to move, threatening the safe storage of seeds. Therefore, insecticide lines should be sprinkled with pesticides around the warehouse to reduce pests invading the warehouse. The stored seeds must also be inspected frequently. During the inspection, the designated area sampling method shall be adopted. That is to say, the seed heap shall be divided into three layers of upper, middle and lower layers with 5 points for each layer. A total of 15 points shall be sampled and then used for a diameter of approximately 30 cm. The small hand sifted through the screen, generally after 3 to 5 minutes of the screen to calculate the pest density (heads/kg). Most of the beetle pests have a pseudo-dead nature. They can be caught out of the beetle and placed in the palm of your hand or you can breathe a little more heat. The pests will crawl. Once signs of hazards are found, they should be immediately treated with exposure, freezing, wind screening or fumigation. Third, the anti-return spring weather gradually warmer, the ground began to thaw and return to the tide. Seeds near the ground, walls, columns, etc., tend to absorb moisture and cause mildew and mildew in the seeds. In general, isolation measures should be taken to raise the seeds up to about 50 cm with planks, etc. The distance between the seeds and walls, columns, etc. should also be kept at a distance of 50 cm or more to prevent the seeds from absorbing moisture. The moisture content of the seeds should be checked regularly. If problems are found, measures such as ventilation and drying should be taken.
