Under the present summer harvest of good crops, many farmers' homes are full of food. Due to lack of knowledge on custody, coupled with high summer temperatures and humid air, food is susceptible to insects and mildew. To this end, here are six methods for storing food in the summer. Hypoxic storage. In hypoxia custody, plastic films or other closed containers must be used to seal the food, isolate it from the outside air, use its own respiration, consume oxygen, and accumulate carbon dioxide, thus suppressing the mold. The method is: After the sun dried grain is filled into the container, immediately cover the grain surface with plastic film, and the surrounding surface should be buried 30--50 cm below the grain surface, so as to be tight and tight and ensure airtightness. However, it is not appropriate to use this method to leave food. Sun exposure method. Choose a hot sunny day, first clean the drying field, heat, and then spread the insect food thinly on the drying floor, thickness of 3--5 cm, and often flip. The grain temperature should be controlled at 45--52°C, the grain temperature should be about 48°C, and the exposure should be 4-6 hours. Except for wheat, it can be hotted outdoors and other foods should be re-entered when the grain temperature drops to near the air temperature. Exposure to insecticide must be observed in rice and peanuts. Other foods and oils can be used. Lime method. The sun dried grain is put into a container, and the good quality lump lime is selected. It is packed into 5 kg of 1 bag by sacks, buried in the grain heap at a depth of 30--50 cm, and buried in 1 bag per square meter. After a good time, cover the food surface with a plastic film and tightly press it around. After burying it for a month, remove the lime. Insect pests and phosphorus mixed grain method. According to the ratio of 0.5 kg of wheat bran per 20 g of insecticidal phosphorus emulsion, mix pest control phosphorus, wheat, and wheat bran uniformly and dry. The foodstuffs to be dried and stored in Yangjing will be uniformly mixed in the ratio of 1:1000, and will be stored immediately. When the food is consumed, the wheat stubble can be blown. The calcium carbide method. Put insect foods in altars, jars, jars, drums, or leak-proof plastic bags. Use appropriate amounts of wet sand, such as plates and bowls, and place them on the grain surface. Then press 500 kilograms of grain and use 50 grams of calcium carbide. Pour it evenly onto the wet sand and immediately fasten it with a plastic film or newspaper paste. After 3 to 10 days, the pests are all killed. Boil water dipping method. This method can be used to eliminate bean pests such as mung beans. The method is: burning a pot of boiling water, keep boiling, the beans wrapped with gauze or into a small bamboo basket, into the boiling water pot and scalded for half a minute, immediately remove the thin booth to dry, that is to achieve insecticidal effect.
