(a) Variety selection plan Fresh-keeping storage of watermelon should be thick and tough medium-late-maturing varieties, requiring dense melon meat, relatively low water content, mature from July to August, but also should be no mechanical scars and pests and scars .
(2) The large number of watermelons that have been listed on the market after ripening is almost impossible to meet the storage requirements because they are currently sold and sold. Therefore, it is necessary to purchase and purchase from the place of origin of watermelons, request watermelons to stop watering for 10 days before harvesting, choose low-temperature and dry sunny days when picking, use scissors to cut 2cm long guati, and avoid hard to prevent wounded watermelon. Take care when transporting to avoid mechanical trauma.
(III) Preservation
1. Preservation agent soaking Nanjing Institute of Vegetable Research and other units developed a new type of watermelon preservative-BVA1 preservative agent, which is an active substance extracted from Chinese herbal medicine, which is a natural biological preparation, diluted at a concentration of 1%, soaked in watermelon 2 After -3min, it can be kept fresh for 1-3 months according to storage conditions. Of course, other melon and fruit preservatives can also be applied.
2. Saltwater immersed The former Soviet Union’s agricultural sector concluded a simple preservation method. The watermelons to be prepared for storage were soaked in 15% salt water for 30 minutes. After soaking, they were air-dried and sealed in polyethylene bags. According to the storage conditions, they could be preserved. -No deterioration in quality for 5 months.

First, the process of watermelon watermelon juice production process of raw materials → selection → cleaning → peeling → crushing → juice → filtration → deployment → degassing → homogenization → high temperature instant sterilization → filling sealing → inspection → watermelon juice finished , Can also be made of watermelon sauce, watermelon soda, watermelon sparkling wine, watermelon vinegar and processed watermelon seeds Second, storage and preservation of fresh watermelon is very short, mature fresh watermelon preservation period is only ten days to half months. If we can make the watermelon extend the shelf life, first, the concentrated ripe watermelon will be listed on the market after being stored, which can reduce the contradiction of supply exceeding demand and extend the period of sale and consumption. The second is the change of the buyer's market after preservation and storage. For the seller's market, after the fresh watermelon is sold out and then put on the market, according to the law of market surplus and deficiency, you can achieve better economic benefits.
