The natural preservation period of raspberry berry is only 1-3 days, and it is highly perishable. To extend the shelf life of strawberries, it must be scientifically harvested, sorted and carefully stored. Scientific harvesting of different strawberry fruit has inconsistent maturity, so to pick it up once a day or the next day, all ripe strawberry fruit must be harvested every time to prevent it from being over-ripe and rot and affect other strawberry fruit. The appropriate time for harvesting strawberry fruit is early morning, before 10 o'clock in the morning and in the evening, and it cannot be harvested at other times. The skin of the strawberry fruit is extremely thin. When harvesting, it must be taken lightly, lightly picked, and taken together with the handle, and the handle can be cut off with a nail, and one can be picked. When fresh fruit fruits have more than 70% coloring, they can be harvested. This kind of fruit is of good quality, beautiful in shape and relatively resistant to storage and transportation; for strawberry fruit, such as jams, fruit juices and jelly, etc., should be ripe when the fruit is fully mature. Harvesting, this fruit has a high sugar content, a lot of juice, and a strong aroma. The fruit used for canning needs uniform size, 70-80% coloration, harder pulp, and better coloration. Graded packaging In order to ensure that the strawberries that are harvested are not squeezed and bumped, the collection containers should be cartons or plastic boxes, bamboo boxes, etc. The boxes should be filled with soft goods. Generally, 2.5-5 kg ​​of strawberries per box is appropriate. When harvesting, it is best to classify the edge and remove the deformed fruit, over ripe fruit, rotten fruit, and pest fruit. Fruit grading standards are as follows: single fruit weight is more than 20 grams for large fruit, 10-20 grams for the fruit, 5-10 grams for the small fruit. Strawberries under the style should be placed in a cool place or in a pre-compartment. When transporting, it is best to use a small transparent plastic box to load strawberry fruit. The single box of fruit is 0.25-0.5 kilograms, and then it is loaded into a large box with a load of not more than 5 kilograms.
