Celery delay storage
Appropriate harvest. Fresh preserved celery should be kept as late as possible on the premise of no frost or frost (to prevent it from being exposed to frost in open field, plastic film or straw can be used at night before and after frost fall). Water should be poured 1 to 2 days before harvest. The first is to increase production and improve quality; the second is to increase the amount of soil in the root, which is conducive to preservation. Harvest to deep cut, leaving about 6 centimeters. After cutting, remove yellow leaves and diseased leaves, and bundle them into 3kg or so small bundles. Each bundle is best bundled with upper, middle and lower lanes for easy access during storage. Code storage. Before the celery enters the greenhouse, it is made into a width of about 1 meter in the greenhouse and about 20 centimeters in height. On both sides of the pole, nail up the column and tie up the crossbar. Place the celery horizontally and horizontally in a bundle. Note the tightness between the bundle and the bundle. After the code has been poured, the water is poured one time, and then the straw film (or glass) is immediately covered with a straw curtain to prevent the room temperature from rising due to sunlight. The indoor temperature is better to maintain at 0-2 degrees Celsius. When the temperature is too high, it should be ventilated and cooled. When the temperature is lower than minus 2 degrees Celsius, thermal insulation or heating measures should be taken. In addition, during the storage process, it is necessary to inspect frequently and pick out bundles that are difficult to be stored, and market them at any time according to market conditions. Fake live storage. That is, use the greenhouse protection facilities to plant celery. Before the ground is about to be frosted, the young celery will be rooted and excavated from the high-density resort. It will be planted in a greenhouse and will be protected from freezing injury by increasing the cover and warming methods, allowing it to grow slowly, delay the harvesting period, and achieve freshness. purpose. Prevent hollowing. When the celery is hollowed out, its quality will be greatly reduced. Not only it will taste bad, but also the nutrients will be lost and it will not be edible. In the greenhouse, falsely hold live celery, the temperature should not be too high, otherwise there will be a hollow phenomenon. At the same time, science should be used for watering. Usually, water is poured every 15 days, and small water is allowed to slip through. Fifteen days before going on the market, you can continue to pour 2 times with Dashui to keep the celery crisp and not hollow.
