Recently, I learned in an interview with major grain producing areas such as Heilongjiang and Jilin that farmers are reluctant to sell because of the decline in corn prices. The local food department is worried that the warming of the weather will cause mildew and deterioration of the corn, causing greater losses to the farmers, vigorously promoting scientific grain storage technology, guiding farmers to put the corn on the shelves, storing them off the ground, ventilating and drying, and selling at the right time to realize the grain yield.

Reduce food post-harvest losses and realize the increase in grain yield

The waste of post-harvest losses in China is staggering. Due to the simple storage of grain storage facilities for farmers, the omission, excessive or extensive processing of grain handling, the annual food losses in China have reached more than 70 billion jin. Bringing influence to national food security that cannot be ignored. In recent years, China's grain output has been continuously improved. The national grain inventory is at a historically high level. The contradiction between storage and storage in some major producing areas is extremely prominent. The quantity of open-air grain storage is large, ensuring the quality of stored grain and the safety of fire safety. Strengthening the scientific management of post-harvest food and effectively solving the problem of serious loss of food post-production loss is also a strategic measure to ensure national food security.

Saving food, in fact, is equal to increasing production, loss and waste, and space for reducing grain. At present, the post-harvest losses of food in developed countries are usually within 3%. According to this calculation, China can save more than 35 billion kilograms of grain per year, equivalent to 200 million people for one year of rations. Reducing the post-harvest losses of grain will effectively alleviate the pressure on China's grain supply, production increase and financial support. At present, China's grain production is facing a lot of challenges such as high production costs, shortage of land and water resources, deteriorating ecological environment, and increasing difficulty in increasing grain production. Reducing post-harvest losses should be a strategic choice to ensure national food security.

Therefore, it is necessary to speed up the formation of a government-led, enterprise-implemented, national-involved, and joint-action food-saving reduction mechanism, and reduce food through measures such as implementing scientific grain storage projects for farmers, strengthening the construction of warehousing and logistics facilities, improving the utilization rate of grain processing, and strengthening education guidance.
