(I) Storage conditions
1, temperature 0 - 1 °C.
2, relative humidity 90-95%.
3, the gas composition O2: 2-4%, CO2: 3-4%.
(II) Storage methods
1. The storage and digging pits are 55-60 cm deep and 1-1.5 m wide, and the pit floor is paved with fine soil. The fresh leaves are wrapped and wrapped in balls, tied with rope, rooted and excavated, planted in the pits tightly in the pits, buried with fine soil roots, watered immediately after prosthesis, and appropriate cover to prevent shading. At the beginning of storage, the grass mats were covered with shading during the day and ventilated at night. The temperature was maintained at 2-3°C; the latter was protected against cold and frost, and the thickness of the coverings. When the flower ball grows to about 0.5 kg, it will be sold on the market.
This storage method is generally only applicable to younger flower bulbs. Mature flower bulbs should not be stored with prostheses, otherwise they are prone to scatter.
2, cellar method used for cellaring is autumn broccoli, generally harvested in October-November, harvest should be selected to be carried out on a sunny day, leaving 3-4 leaves outside the flower ball, remove the disease, injury flower ball. When entering the pit, cauliflower can be scattered directly in the pit or placed on the storage rack. When stacking, care should be taken to leave proper ventilation. The plastic film can be used to cover the above, but it is not sealed, and once every day, the air is released and maintained. The temperature in the pit is 0-1°C, and the humidity is about 90%.
3, cold storage at 0-1 °C under the conditions of cauliflower single-ball plastic bag with the best method. Specifically, a bag of about 3035 cm2 in size is made of 0.015 mm thick low-density polyethylene plastic film. Each flower ball is put into a bag, folded, and placed in a basket or on a shelf. In order to maintain the white ball and prevent the growth of mold, Kemyling fumigation can be used during bagging. In addition, the leaves of the outside of the bulbs can be retained according to the length of storage. Within two months of storage, the main leaves are leaves. If the leaves are more than two months old, the outer leaves should be removed to prevent the leaves from becoming rotten during storage. . This method not only reduces the evaporation of moisture during storage, but also avoids cross-infection between flower balls, and has a long shelf life.
(3) Major Diseases and Control Measures During Storage The main disease during storage of broccoli is caused by Alternaria spp. causing moldy or brown spots on the bulbs. Symptoms often appear as depressions at moldy spots, and spread to pieces when severe. Mycelial growth occurs under high humidity and is in a wet and soft state. There are also gray mold, root mold rot and bacterial soft rot.
Prevention methods: In addition to maintaining a constant low temperature, the use of chemical agents, but also should take measures to prevent freezing damage, mechanical damage, reduce field sickness and other measures.
