1. The choice of storage species should be based on the selection of species with strong storability, which is an important condition for prolonging its storage period. Such as Jin research series of cucumber, the general epidermis is thicker, the flesh is plump, the solid material is substantial, more resistant to storage, but the tolerance of the cucumber between the varieties of cucumber is not the same. Beijing small thorny cucumber is small, thin skin, epidermis, and more easily damaged, storage conditions slightly discomfort, melon meat into pink, melon taste bitter. Therefore, Beijing's small thorny cucumber is not resistant to storage. When selecting varieties, in addition to considering the storability of the varieties, the quality of the cucumber varieties should also be taken into consideration. In particular, attention should be paid to the aroma and vitamin content of the cucumber. 2. The picking of the fruits is an important part of storing cucumbers. Pour water once in 1 to 2 days before picking so that the melons can fully absorb water and grow sufficiently to prevent loss of water through storage. Picking cucumbers will not dew in the morning. The temperature is low. When picking the melon, it is best to use scissors to cut the melon pedicle 3 cm. Take care when picking to avoid peeling and tumor damage. In order to prevent mechanical damage during transportation, it is best to use a basket of melons, and put soft paper in the basket, cucumber harvested from the greenhouse in the winter, be careful to keep warm transport. 3. Choosing the storage of cucumbers requires the top flowers to be pricked and the color green. To select the melons growing in the middle of the plant, the melons are mostly straight. sturdy. Do not pick melons that are close to the ground because they are in contact with mud, with germs and perishable. Also do not gourd the top of the melon, because the melon pods are aging, the melon's content is insufficient, the melon shape is more irregular and intolerant of storage. Also pay attention to the maturity of the melon and choose not to be old or not tender. Medium ripe melons, tender and small melons and old ripe melons have shorter shelf life. The appropriate harvesting standard for storage melons is small. No straight white line melon.
