Good benefits can be obtained by storing broccoli in cold winter and early spring. The suitable storage conditions are that the temperature is 0? 1 ℃ (below 0 ℃ will be frozen, above 8 ℃ will turn yellow, dark), the relative humidity is 90%? 95%. The air in the storage environment accounts for 3% of oxygen and 4% of the air, and carbon dioxide does not exceed 5%.

Autumn harvest as long as not frozen damage, the later harvest is more conducive to storage. Do not water 7 days before harvest. To take leaf-binding measures, that is, to break the leaves around the flower bulb in at the flowering stage by breaking two or three pieces to cover the flower bulb, or by tying up three or four leaves and tying them gently with straw or rope. So that sunlight can not be directly into. 7 when mature harvest more resistant storage. In order to prevent yellowing and shedding of the outer leaves, 25 ml / L 2,4-D solution or 10-50 ml / L 6-benzyl adenine solution should be sprayed one day before harvest. Spray 3000 ml / L carbendazim or thiosulfan solution onto the flower bulb. It can reduce decay. Cauliflower bulb formation is also very inconsistent among plant individuals, should be harvested in batches. When harvest should pay attention to choose the cauliflower which is big, the flower branch is dense, the bud is dense, the margin is not yet scattered. Cauliflower plants for artificial planting must be harvested with roots and leaves. The cauliflower plants stored by other methods should retain 3-4-leaf-coated bulbs in order to reduce mechanical damage during transportation. Apply moisturizing material to cover or plastic film packaging during storage.

A small bag of 30cm × 34cm was made of 0.04mm thick plastic film, packed with single flower ball, folded without sealing, and put into the cold storage at 1 ±0.5 ℃. The storage period was about 65 days, and the commodity rate was about 94%. The plastic film bag was used, the air in the bag was in a static state, the cauliflower had sufficient moisture, expanded pressure, strong and brittle tissue and less weightlessness under high humidity condition. The temperature in the bag was also relatively stable, which ensured the normal progress of physiological and biochemical activities of cauliflower, and could be protected from the mutual infection of bacteria and mechanical damage, thus greatly reducing the incidence of disease.

As soon as possible, put the cauliflower in a cool, ventilated place or cold store to remove the field heat. Pre-cooled broccoli according to grade, specifications, origin, batch code into the cold storage room, at least 1 meter from the evaporator. When the cauliflower box (basket) refrigerates, the flower bulb should face up: when the box (basket) is placed, should not harm the lower layer cauliflower flower bulb is appropriate. When the single flower ball bagging is refrigerated, a single flower ball shall be placed in a 0.015 mm thick polyethylene plastic bag (30 / 35 cm × 35 x 40 cm), and the opening shall be placed in the box basket), and when placed in the yard, the flower bulb shall be required to face down. Made out of condensed water droplets produced in a bag on a flower bulb. It is moldy and rotten. The cold storage temperature should be kept at 0 ±0.5 ℃, and the relative humidity in the storage should be 90% ~ 95%. Under the above-mentioned conditions, according to the variety and origin of cauliflower, the cold storage period is 3-5 weeks, and the cold-storage period is 6-8 weeks in single-flower-ball bagging method, according to the variety of cauliflower and the origin of cauliflower.

Make a account of plastic film, store broccoli in the account, fill the account with ordinary nitrogen to reduce the proportion of oxygen in the account, and put calcium hydroxide into the account to absorb carbon dioxide, and use a pump or a low pressure fan to remove the gas in the account. Use a gas analyzer every 2 days to measure oxygen and carbon dioxide in the account and adjust it to the required range. The optimum temperature for controlled atmosphere storage of cauliflower is 3 ~ 8C, oxygen control is 2% ~ 5%, carbon dioxide is 0% ~ 6%, this method can be stored for 3 ~ 4 months. Dipping the root of the flower bulb with 50 mg / L 2,4-or 6-benzyladenine before storage helps To prevent yellowing and shedding of the outer leaves. Spraying 3000 mg / L benzendazim or thiothiazim solution into the flower bulb at the time of storage can reduce the decay of the flower bulb.
