Because the corn embryo is large, nutrient-rich, breathing is strong, the amount of microbes is large, and the original moisture of corn in northern China is high. At lower temperatures, mold can also multiply and cause mildew. To this end, the experts specially reminded the peasant brothers that after the corn harvest, they must pay attention to the anti-mild work in the process of storage, so as not to cause losses to themselves. How to prevent corn mold? Experts pointed out that we should start from the following aspects.
First, do a good job before degranulation. Since the grain embryo is buried in the cob of the ear when the corn is not threshed, it has a certain protective effect on the insect damage. Therefore, it is advisable to adopt the corn ear storage after harvesting. Corn ear gardens should be stored in large yards. In autumn rain and warm winter seasons, plastic film should not be used to close the lid. In rain and snow, corn stover, grass lotus and other items should be covered best. To prevent the inner temperature of the humidity and a large amount of mildew. It is best to take the method of stacking and palletizing. For the small amount of corn, and not eager to sell, it is necessary to take the method of stacking and keep the corn ear in a special stack for storage. The shape of the stack is divided into two types: rectangular and circular. Due to the terrain, it is made of wood or sorghum straw. The bottom is padded about 0.5 meters, the diameter is 2-4 meters, and the height is 3-4 meters. If the amount of corn is large or the farmer does not have the conditions for stacking, it should be temporarily kept by means of yards. The corn yard scorpion should have a bottom of 20 cm or more. According to the moisture level of the corn, determine the time and number of ups and downs to avoid the problems of low temperature mold and degradation of the corn cob due to poor ventilation. For new plots of different plots, different varieties, different maturity, different quality and different moisture, different measures should be taken to take the stack or yard storage to avoid mass confusion and increase income.
Second, we must choose bar threshing at the right time. It is necessary to determine the threshing time reasonably depending on the moisture condition of the corn. Prepare the site and other preparations before threshing. If there is no fixed, clean and spacious site, the flat ground water can be thawed and then threshed to reduce the loss of soil. At the same time, the moldy sticks and the uncooked sticks should be taken out, the tops of the cockroaches should be smashed, and the cockroaches should be smashed separately and stored separately to avoid the mutual mixing and threshing, which affects the overall quality of the corn.
Third, we must do a good job of corn threshing. After corn threshing, it is necessary to avoid the accumulation of large piles of storage. If it cannot be sold before mid-April, it is necessary to choose the method of wind picking, drying or drying according to the actual situation, and the farmers should keep the corn in the summer. It is necessary to first reduce the moisture of corn to less than 14.0%. Drying should be determined according to the size of the drying, usually in mid-March, the thickness is about 8-10 cm, the first two days of frost big 3-4 times a day, when the ground is not frosted when the ground is seen with the sun The angle of light irradiation is turned over by wood milling every hour, and the whole river is once again every other day (to prevent the sandwich). When it reaches safe moisture, it needs to pass two layers of sieve to remove the impurities and broken surface to enter the warehouse, and ensure the food is cool and dry. ventilation.
