Pomegranates have a long flowering period and should therefore be harvested in stages according to their maturity and species characteristics. When picking, the diseased fruit and cracked fruit should be picked by special personnel and treated centrally to prevent the spread of disease and infection. When picking on rainy days, it is easy to cause pathogens to invade and cause rot. Therefore, it should be picked on a sunny day. When harvesting, twigs are hand-picked, fruits are picked in one hand, and fruit stalks are about 1 cm in length. The fruit should be picked and released as lightly as possible to prevent the pomegranate fruit from mechanical damage. In particular, internal injuries should be prevented. When the fruit is squeezed and internal injuries occur, the seeds in the peel are crushed, but they are not visible from the outside. Afterwards, during storage and transportation, the sap from the crushing process will affect other unbroken kernels and degrade them. Pre-storage treatment: 1. Fruit selection and grading: After fruit grading, diseases, fruit wounds, and cracked fruits should be removed. Fruits that may have internal injuries should also be singled out as soon as possible and sold immediately. Sound and non-injured fruits should be sold, and their weight should be divided according to their weight. Five grades, special grades (350 grams or more), one grade (250-350 grams), two grades (150-250 grams), three grades (100-150 grams), and others (with less than 100 grams of fruit weight). Special grade, first grade fruits can be used for foreign trade, foreign transport, and other fruits and wounded fruit can be used as processing raw materials in addition to the nearest sale. 2. Disinfectant treatment: use jujube Pomegranate antistaling agent No. 2 1000 times solution, 50% carbendazim 1000 times solution or 45% ceftazidime suspension agent 800 to 1000 times solution, dipping fruit for 3 to 5 minutes, and after drying Storage; When the storage capacity is large, the above-mentioned medicaments can be sprayed onto the fruit surface by spraying, and dried and stored. Storage method: Temperature and humidity: Pomegranate thermophilic, its basic requirement for storage is high temperature and high humidity. 0 °C cold injury will occur, tissue necrosis. Therefore, the fruit should not be stored at a low temperature of 0°C, the appropriate temperature is 4 to 5°C, and the suitable humidity is 95%. The following methods are commonly used for storage: 1 Hanging: For hanging fruits, a fruit stem should be kept during harvesting, tied together with a string, suspended in a cool house or packaged in newspapers or plastic films. If it hangs in a room with a small temperature and humidity change, it can be stored before and after the Spring Festival. 2 cylinders, urns (cans) possession: use a new altar or cylinder, and lay a layer of fine sand or wheat straw about 5 cm thick on the bottom. Store the pomegranate in a cool, ventilated place for three or four days (pre-preserved pomegranate has been treated with a bactericidal agent) and layer it into containers until it is full. The mouth or cylinder mouth is sealed with a plastic film and fastened. Check once a month after storage, if rotten fruit should be promptly removed. This method can be stored until March and April of the following year. 3 Dry Well Pit Storage: In the dry section, dig a dry well with an inside diameter of 80 cm and a depth of 2 meters. Dig a few holes in the bottom of the bucket to pomegranate. Before entering storage, the fruit should be strictly selected, and the disease, injury, and broken fruit should not be stored, and the fungicide should be sprayed at the same time. When entering the storage, the pomegranate fruit should be stacked into the hole, and a small air hole should be left when covering the cellar lid. 10 to 15 days to check once, remove rotten fruit, generally after the cold dew into the pit, can be stored until after the Spring Festival. 4 Polyethylene plastic bag storage: The pomegranate, which was pre-cooled and treated with a bactericide, was put into a polyethylene plastic film bag, and the bag was put in a cool room for storage. Stored in this way for 140 days, the pomegranate fruit is still fresh. Pomegranate fruits treated with fungicides can also be packaged in plastic bags. The fruits are stored at 3 to 4°C for 100 days. The freshness of the fruit pieces is good, and the skin disease is light. The plastic bags are more than other packages. The effect of the measures will be good. 5 heaping: on the floor or earth floor that is not affected by smoke and dust, or to store pomegranate fruit with a large cabinet, firstly lay a layer of fresh pine needles on the floor or the bottom of the cabinet, put a layer of pomegranate, and then spread a layer of pine needles. . Such a layer of fruit is piled up on one side with pine needles. The top cover is covered with pine twigs, straw and other coverings. The mulch is checked every half-month, and the rotten fruit is removed and a pine needle is replaced. Stored varieties can be stored in April-May in the following year using this accumulation method. Pay attention to the fruit before the accumulation, must first wash the skin with water, pre-cooling.
