Before the storage of the apple in the warehouse, the apple must be carefully cleaned, and debris, garbage, etc. must be cleaned out of the library, then sprayed with 1% formalin solution or fumigated with sulfur for 2 to 3 days (per cubic meter). Rice uses 10 grams of sulfur). Apple should be properly ventilated when it is in storage.
Apples that are carefully stored in the warehouse must be carefully selected from harvesting, and fruit pickers should cut their nails lightly and gently to ensure that the fruit stems are intact. A layer of cloth should be sewn in cages or baskets used for fruit picking in order to prevent squeezing bumps. The selected fruit should be diluted with 4% of NPK 120 to 600 times spray or pod sterilized. After the fruit surface liquid is air dried, the selected fruit is put into the field trench or garden backlit cover and precooled. , ready for storage. Do keep in mind that the freshly picked apples must not be rushed into storage because the fruits of this time are very active and the amount of heat released is greater. At this time, storage affects the storage effect.
Fruit bank management Fruit bank management is mainly the regulation of temperature and humidity. The suitable storage temperature for apples is 0°C to 2°C and the relative humidity is 80% to 90%. Therefore, in the early stages of apple storage or cell entry, it is necessary to check the temperature. If the temperature is too high, adjust the cooling equipment in time or use natural ventilation for cooling. Natural ventilation cooling time should be selected before dawn, when the outside temperature is low, easy to cool. The humidity in the cellar is generally easy to control, and the humidity of the built-up fruit bank is difficult to grasp. If the humidity is low, on the one hand, it is necessary to check whether the fruit bank is closed tightly, and on the other hand, artificial humidity must be used to keep the humidity stable. In addition, the diseased fruit and rotten fruit found during the inspection should be brought out of the fruit bank in time to prevent the spread of germs.
Apples that are graded and sold in storage are best sorted and packed according to specifications prior to sale. Do not mix. Mixed packaging seems to simplify a bit of program, but revenue will be significantly reduced. The astute fruit growers even post the same apple from an orchard. The mixed sale sells for 1.8 to 2 yuan per kilogram. If the sale is graded, it costs 2.8 to 3 yuan per kilogram of apples. Therefore, the author advocates classified sales, which is actually a value-added method for fruit production. Ji County Agricultural Information Center
