How to store in order to ensure that the citrus sell well, the loss of less use of storage-resistant species: orange, navel orange, grapefruit and Pomelo and other more resistant to storage, followed by Wenzhou tangerine. Fruit picking points: Generally picking oranges in sunny days, Platycodon grandiflorum should be cut flat, gently and gently, to avoid mechanical damage. Treasury disinfection: Stored in ventilated warehouses or ordinary houses can be citrus. Before the storage, the warehouse was cleaned, the rat hole was blocked, and sterilized with carbendazim or thiophanate-methyl 500-fold solution one week before the citrus was stored. Citrus should be ventilated open doors and windows 2 days before storage, in order to prevent bacteria damage affect the storage effect of citrus. Anti-corrosion treatment: The citrus used for storage should be preserved for the anti-corrosion treatment on the day of harvest, and it should not exceed 2 days. The antisepsis and preservation agent is made of 25% Shibaoke 10ml plus 2-3g 2.4-D sodium salt and 10-12.5kg water, which can handle 750-1000kg of orange. The treatment method is to dip the picked citrus fruit into the liquid for 1 minute, then remove it and let it dry. Ventilation pre-storage: Preserved citrus should be stored in a ventilated warehouse, usually pre-stored 5-7 days, in case of rain, can be extended to 10-12 days, usually dried peel, fruit weight loss 3-5% For degree. Pre-stored oranges can be packed in polyethylene film bags and stored as single fruit, or can be stored in bare fruit. Wood storage containers, bamboo baskets or rattan baskets can be used to store fruit. Storage method: When the oranges are stored for storage, they can be selected according to the storage conditions and the size of the warehouse. The main methods include “product†shape stacking, rack storage, and on-site storage. Either way, there should be enough channels and space for managers to operate. Treasury management: During the storage of oranges, warehouse doors and windows are required to be shaded, the temperature inside the warehouse is maintained at 4-10°C, relative humidity is 85-90%, and the temperature difference between day and night is small. At the early stage of storage, high temperature and humidity are likely to occur in the warehouse, shortening the life span of citrus. At this time, it is necessary to strengthen ventilation and reduce the temperature and humidity of the warehouse as soon as possible. When the outside temperature is lower than 4°C, close the doors and windows in time, block the vents with grass, strengthen indoor cold and warm, ventilation, ventilation when the temperature is high at noon. In the late period of storage, when the outside temperature rises to 20°C, the doors and windows must be closed, ventilation should be performed sooner or later or when the temperature is lower than 16°C. When the relative humidity in the warehouse is reduced to 80%, the citrus in the container should be covered with a plastic film to moisturize. The film should be 25-30 cm away from the ground and must not be sealed. The piled citrus can cover clean straw moisture. In addition, the air humidity can be increased by using ground water or water in the basin. Citrus should be inspected regularly during storage to eliminate floating rot at any time, but try not to flip it.
