How to preserve wax gourd with black skin

1, suitable storage conditions. Wax gourd is a cold-sensitive vegetable, which likes temperature and heat resistance. The suitable storage conditions are: temperature 10- 15℃, relative humidity 70-75% and good ventilation. It can be stored at 10- 15℃ for several months. Wax gourd is not resistant to low temperature storage, and chilling injury will occur below 10℃. But the storage is too high, the respiratory rate is accelerated, the tissue becomes soft rapidly, and the pathogenic bacteria multiply rapidly, and the storage period is not long.

2. Preparations for storing melons. Wax gourd has high water content, so tender melon and overripe melon are not suitable for storage. Therefore, the storage of wax gourd requires nine-ripe, thick skin and thick meat, dense texture, good quality, shiny green skin and waxy varieties. Stored melons can't frost. During the growing period, you should put bricks under the melon or dry them to prevent the sun from exposure. Irrigation is not allowed before harvest 1 week. Wax gourd should be protected from rain before storage. Leave 3-5 cm seedlings when harvesting. Choose to cut and pick with scissors when it is cool in the morning. In order to prevent mechanical damage and microbial infection caused by collision between melons, wax gourd is wrapped in newspaper. In the process of handling, handle with care to prevent scratches and bumps, especially to prevent falling and rolling, so as to avoid internal damage of wax gourd and great hidden dangers for storage.

3. Preparation of storage kiln. Most of the storage kilns are semi-underground, that is, the height of the kiln chamber is about 3.6 meters, with 1.8 meters above and below the surface, and kiln windows are set around, facing each other, which is convenient for ventilation. The size of the storage kiln depends on the number of stored wax gourd. The building with this structure has the excellent characteristics of high constant temperature, coolness, simple ventilation and easy control of humidity. 2-3 days before the winter melon is put into storage, the warehouse should be fully disinfected: after the kiln warehouse is closed with potassium permanganate smoke, the temperature of the warehouse should be reduced to 65438 03℃, and then the winter melon to be put into storage.

4. Placement of wax gourd. Choose carefully selected, neat and undamaged mature wax gourd and store it in warehouse or shelf. It is best to store it on the shelf and put it on a single floor. Because of good ventilation, the shelf storage of wax gourd is better than stacking storage, but the shelf storage of wax gourd should also be covered with soft ventilation materials such as hay before putting wax gourd on it. When stacking, you should first lay hay or straw curtains on the bottom of the library, and then put wax gourd on it, generally no more than 3 layers, so as to avoid crushing and damage. When stacking, leave a passage for inspection. In the process of placing, it is advocated that melons should be placed in the cellar as long as they are in the ground, that is, they should be placed according to the state when they grow in the ground, and they must not be misplaced, because the pulp of melons has adapted to its gravity direction and is not easy to crack, so the storage time can be longer.
