First, site disinfection 1. Stacking site first with 1000 times thiophanate or 500 times carbendazim spray disinfection. 2. The fine river sand or straw is soaked with the above drug concentration until it is water-dried, and is laid on the ground about 6 to 10 cm thick. The dryness of the river sand requires hand-kneading to form a mass; the hand-sprinkling is spread out. 3. For harvesting fruit, except for external grades and urgent fruit sales, if it is necessary to keep fresh, the dipping time is generally within 24 hours after fruit picking. Second, stacking 1. The fruits of the diffused fruits are piled 5 to 6 layers upside down, and the piles are thick and easily crush the following fruits. 2. Cover the placed fruit with a thin film or straw. Third, management 1. After the stacking of 3 to 4 days, water droplets appear on the surface of the film, which is called sweating. Pick out the wounded fruit and carry out fruit-flushing every 10 to 15 days to pick out the rot fruit and dried fruit. 2. The room temperature for stacking fruits should be controlled below 10°C. The temperature is too low to seal the window sticker. 3. Do not place aromatic substances such as rice bran on the piled fruit grounds. Do not eat tobacco and alcohol before the custodial staff turns fruit. Fourth, preservation of drugs and specific operations 1. Anti-corrosion film - Beijing 2B. The surface of the fruit is soaked with 1:30 to 1:90 times of Jing 2B. The formed film has an inhibitory effect on respiration and can reduce the loss of water. Both orange and orange can be used. The storage period of 100 to 120 days can be sprayed with a sprayer and the effect is best. 2. Thin film single fruit storage. Sweet oranges were harvested at mid-November-eight, and they were picked by Huang Liuqing. On the day of harvest, they used 2,4-D250 microlitre/litre plus thiophanate 1000-1500 times mixed liquid to diffuse fruit and 500 kg of fruit can be soaked. About 4 months out of the library. Red oranges were harvested around November 10, harvested on the same day with 2,4-D750 microliters/liter gattophanine 1000-1500 times diffuse fruit, pre-storage 10 to 15 days, storage thermostat temperature requirements sweet orange 4 ~ 5 °C , Red orange 2 ~ 3 °C, 30 ~ 60 days out of storage, relative humidity is generally 85% ~ 97% is appropriate. 3. Sand storage: First thiophanate-methyl 200 mg / liter gitobujin 1000 ~ 1500 times liquid soaked fruit after sand storage, a layer of dried orange layer of sand, can be stacked in 5 layers, and finally covered with plastic. It is required that the fruit pedicle be stored upwards, generally about 15°C. When the temperature reaches 20°C, the film will be opened and a small amount of water will be sprayed to make the river sand moist. 4. Starch plus baking soda storage. First thiophanate 1000 ~ 1500 times liquid spray fruit trees. After harvesting, the fruit was mixed with 1% baking soda and a small amount of starch. After cooling, it was allowed to cool for 3 days. After 15 days, it was sealed in a plastic bag. 5. Garlic fresh citrus. Use 9 parts of water to boil at 70-90°C, add one portion of garlic water (mashed garlic liquid), dip the fruit after cooling in boiling water for 10-15 minutes, and keep it fresh for about 100 days. The sour taste will be light and the sweetness will increase. 6. Conventional storage method. Use 2,4-D200 microlitre/liter geropentine 1000-1500 times liquid diffuse fruit, put into the cellar or air-raid shelter, 100 days out of the library. 7. Orange rot preservation. Use 2,4-D250 emblem l / l plus orange rot 100 times liquid dip fruit, the effect is better. When the fruit turns green and yellow, the time is from 1 to 7 November, 250 μL/L can be used for fruit soaking; yellow to orange, from 8 to 14 November, with 350 μL/L; fruit color is deeper 15 to 20 November, with 400 μl/l fruit dip; orange bright red, November 21 to 30, with 500 μl/l fruit dip. Early harvest can be stored for 2.5 to 3 months, medium harvest can be stored for 1 to 2 months, and late harvested fruits can be stored for 1 month. 8. Loose hair and convulsions. Use loose hair and cypress more than red and dry 3 to 5 times. A layer of fruit, a layer of loose hair and cypress 3 to 6 cm thick, can put 3 to 5 layers. Storage 150 ~ 250 kg, generally can be stored for 2 to 3 months, check every 10 days to half months. 9. Shen Xian No. 2 preservation method. Shenshen No. 2 can inhibit the respiration of fruits, delay the consumption of internal acids and improve the storability of fruits. For a long period of time to maintain the flavor and appearance of the fruit, the peony herb also contains several highly effective, broad-spectrum, safe fungicides that inhibit the spore germination of P. syringae pv. Cause malformation mutation of germ tube to lose its pathogenic ability. It can reduce the rot of the fruit, and at the same time has a high-molecular film-forming substance. Can form a layer of film on the surface of the fruit to reduce water loss. Increase the sheen of the fruit surface. 200 kg of water is used for fresh water and 2 kg of fresh produce is added to 1 kg. Stir well and the concentration is diluted to 0.5%. Dipping the citrus fruit collected for the same day for half a minute, air dry, pre-storage for about 5 days, and then put in fresh plastic bags.
