Storage characteristics Cucumber, also known as cucumber and courgette, is native to India and the tropical regions of Southeast Asia. It is a crispy fruit for consumption. It has a high water content. After harvesting, it will age after being stored at room temperature for a few days. The epidermis turns from green to yellow. The head of the melon is gradually enlarged due to the continued development of the seed, the tail tissue shrinks and becomes awkward, the melon shape becomes a stick-like shape, the flesh is soft, the acidity is increased, and the eating quality is significantly decreased. The texture of cucumber is crisp and tender, and it is susceptible to mechanical damage. The melon thorn (type of thorn melon) is easy to get rid of, forming a wound out of the juice, so that the infected bacteria cause rot. 2. Storage process (1) Harvest: The cucumber used for storage is preferably the melon grown in the middle of the harvested plant, commonly known as the “waist melonâ€; do not collect the melons that are connected to the ground for storage, because even the sweet potatoes. In contact with the soil, the melon body has many germs, it is easy to rot, and it is not necessary to harvest the knotted melon at the top of the plant for storage. Because this melon is the late melon when the plant is depleted, the melon has insufficient contents, in appearance. It also shows little rules and has a short shelf life. Cucumber harvesting period should be timely and early harvesting. It is required to be carried out when the melon body is greenish, the top bud is thorny, and the seed has not yet expanded. That is, the straight-lined and enriched medium-ripe green melon strips are selected for storage. The tender melon has more water, less solid matter, and is not resistant to storage. The value of the yellow aging melon is poor and it is not suitable for storage. Mercury melons that need to be stored for a long time should be harvested in the morning to ensure the quality of the melon. (2) Post-harvest handling and packaging: After picking the cucumber, the fruit should be carefully selected to remove unqualified melons with mechanical scars and disease spots, and the qualified melons should be placed in the disinfected dry basket (box). The capacity of the basket should not exceed 3/40 of the total capacity. If the melons with storage thorns are wrapped in soft paper, they should be placed in the basket to prevent the thorns from stabbing each other and rot. In order to prevent the dehydration of the cucumber, the polyethylene film bag can be used as the inner package during storage, and the bag is filled with an ethylene absorbent which accounts for about 1/30 of the weight of the melon, or is covered with a plastic film at the bottom of the stacked package and the four walls. The diseases in cucumber storage mainly include anthracnose, bacterial soft rot, violacem and rhizomania. For storage period of more than one month, fungicides (such as Tecto) and film coating agent can be used before storage. (such as shellac, soluble wax) mixed with fruit soaking to extend the shelf life. 3. Storage and transportation Control conditions: 1 Temperature: The suitable storage temperature of cucumber is very narrow. The optimum temperature is 10~13°C. It will be chilled at 10°C. The seed grows, yellows and rots are obviously accelerated above 15°C. The cold storage with mechanical refrigeration equipment is ideal. Place. 2 Humidity: Cucumber is easy to lose water and become soft and wilting. The relative humidity is required to be kept at about 95%. It can be packed with plastic film to prevent water loss. 3 Gas: Cucumber is extremely sensitive to ethylene. When storing and transporting, care should be taken to avoid mixing with fruits and vegetables (such as tomatoes, bananas, etc.) which are prone to ethylene. The use of ethylene absorbent to remove ethylene during storage has a significant effect on delaying cucumber. Cucumber can be stored in a controlled atmosphere. The appropriate gas composition is 2% to 5% for both oxygen and carbon dioxide. A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
