Beijing Agricultural Technology Extension Station specially proposed technical guidance on the safe storage of grain corn

The safe storage of grain corn should follow the principle of economy, safety and effectiveness, and take technical measures such as mildew prevention and insect prevention according to local conditions to reduce storage losses, do a good job of classification and storage according to quality, avoid reducing grain grades due to mixed harvesting and mixed storage, and improve the quality

Panicle harvesting storage method

Do a good job of drying and moisture-proof: for corn with high moisture content at harvest, natural ventilation should be adopted to improve the quality of precipitation and prevent mildew

Removal of impurities: After the harvest of corn, remove bracts, filaments and other debris, and at the same time remove green ears, diseased ears, etc

Scientific use of storage facilities: generally put the corn fruit ear into a special storage warehouse, select the dry and ventilated location of the foundation, lay the bottom of the substance, prevent the corn ear from direct contact with the ground, cover the upper part, prevent rain and snow from entering the warehouse, and maintain a certain distance between the warehouse and the warehouse to facilitate ventilation

Grain collection and storage method

Do a good job of drying and moisture-proof: corn grains should be fully exposed to the sun or dried after harvesting, and the moisture content should be controlled below 14% before storage

Removal of impurities: corn grain machine harvest often contains more impurity such as unripe grains, broken grains, etc.

Pest control: the main pests of corn during storage are corn elephants, coffee bean elephants, wheat moths, pink spot borer, etc.
