1. Live storage method Using greenhouses to grow celery seedlings, you can borrow greenhouse facilities and use methods of increasing the amount of cover and heating to make celery free from cold damage and grow slowly in the greenhouse to maintain its life. Delay the harvest period to achieve the purpose of preservation. 2, code storage method In the greenhouse code storage of celery, to ensure that celery does not meet the frost, under the premise of freezer, as late as possible, in order to facilitate storage. In order to prevent the celery from freezing in the open, it can be covered with plastic film or straw at night before and after the frost fall. Pour water once every two to three days before harvesting. Firstly, it can increase yield and improve quality. Second, roots can bring more soil to facilitate storage. Harvest to deep cut, leaving about 6 centimeters. After cutting, remove yellow leaves, diseased leaves, bundles of 3 kg or so. Each bundle is best bundled with upper, middle, and lower channels for storage. Before the celery enters the greenhouse, the interior of the greenhouse is made into a file about 1 meter wide and about 20 centimeters high. On both sides of the pole, a column was nailed, a cross bar was tied, and the celery was laterally and horizontally placed in a yard and placed in a ventilated channel. Do not stack too tightly between bales and bundles for ventilation. After the code is poured, it is poured once. Immediately afterwards, the shed film or glass cover is covered with a straw curtain to prevent room temperature from rising due to sunlight. Indoor temperature to maintain at 0-2 °C is more appropriate. If it is too high, it should be ventilated and cooled. When the temperature is lower than -2 °C, insulation measures or heating measures should be taken. In the course of storage, we must always check and pick out bundles that are no longer suitable for storage.
