The harvest of pomegranate should be carried out in stages according to maturity and species characteristics. The signs of ripeness of pomegranate fruit are as follows: 1 Pericarp from the green to yellow, color varieties fully colored, shiny fruit surface. 2 fruit edges appear. 3 The red or silver-white needle awns in the flesh cells are fully developed, and the color of the red granules reaches an inherent level. In the northern producing areas. During the period from autumnal equinox to cold dew harvest, it is suitable for harvesting, and it is harvested too early. The flavor is poor, and the tolerance to storage is also poor. The pomegranates in the south should first take flowers, fruits, and then ripe after harvest. 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 in rainy days, the water in the bowl of the fruit is prone to infiltration and it is easy to cause the invasion of the pathogen and cause decay. Therefore, picking should be done on a sunny day. When harvesting, twigs are hand-picked, fruits are picked in one hand, and fruit pedicels of about 1 cm are used. Lightly pick lightly to prevent pomegranate fruit from mechanical damage, especially to prevent internal injuries. The fruit was squeezed and internal injuries occurred. The seeds in the peel broke, but they were not visible from the outside. Afterwards, during storage and transportation, the sap from the crushing process will affect the remaining unbroken grains, causing them to collapse and deteriorate and lose food value. After the fruit is harvested, the disease, fruit damage, and fruit cracking should be removed. The fruit with suspicion of internal injuries should also be singled out early and sold immediately. The healthy, non-injury fruit used for storage must be sterilized in a timely manner. The test results showed that the bactericidal effect of the jujube farmer Pomegranate Preservative No. 2 developed and produced by the Agricultural Bureau of Zaozhuang City, Shandong Province was good and the use concentration was 1000 times. 50% carbendazim 1000 times or 45% thiabendazole suspension 800 to 1000 times, dipping fruit for 3 to 5 minutes, after drying, storage, storage can be used to spray the above-mentioned agents to the fruit surface Upper, dry and store. Beijing 2B, Beijing No. 1 preservative, sec-butylamine, etc. for the pomegranate preservation effect is not satisfactory. Excerpt from: "Guoshu storage preservation processing Daquan"
