Late-maturing cauliflower is generally harvested in early November. If natural low-temperature storage is adopted, it will be delayed until New Year's Day or New Year's Day. Its management is simple, low-cost, value-added, and cost-effective. Here are three storage methods. First, do a good job of pre-storage processing. Use vacant storage and cellaring. Bamboo baskets are prepared, and the outside of the basket is covered with a layer of polyethylene plastic film, which is then packaged with a sterile pouch. Watering should be stopped 15 days before the appropriate cauliflower is harvested, and a 0.1% fresh green pigment should be sprayed to ensure the freshness and storability of the flower bulb. Then choose a large, non-dispersed, pest-free curd, leave 4-5 leaves cut down, dehydrate naturally in the same place for one day, dip into the bulb with a 1500-fold solution of thiophanate solution to facilitate sterilization. . Then use the outer leaves to put the ball tightly into the basket. After filling the basket, tighten the pouch and plastic film. Move the basket into a cool, ventilated place at near zero temperature and precool for 5-7 days. Then the pouches and plastic film were uncovered and examined once, the mildew balls were removed, and the pouches and plastic films were reassembled to be stored. Unoccupied storage: When the weather is gradually cold from late November to early December, put the basket into the unoccupied room. Pick 2-3 floors, but avoid crushing. The main house in Chaoyang needs to be opened with hanging doors and windows to facilitate ventilation and shading. It will enter late December and gradually close doors and windows according to weather conditions. Watch the outside world at noon on sunny days to open doors and windows for 1 hour. Enter 1-2 months, pay attention to cold. Check the basket once every 10 days to pick out the burned-out ball and market it in time. The entire storage period should try to keep the indoor temperature stable at 1-degree, avoiding sudden fluctuations. Cellar storage method: First, dig a good storage pit, the depth is generally about 2 meters, width of 3 meters or so, the length is not limited. The cellar roof is paved with eucalyptus and corn stalks, covered with 10-15 cm thick soil, leaving 1-2 sunroofs in the center of the cavern, and the larger cellar should have several more. Leave one entrance to the pit at one end of the pit. In the late November or early December, when you move into the pit, you can generally put three layers, and do not squeeze it. After entering the pit, you must open the basket mouth and change the air once, usually about 1 hour. Due to the high humidity in the cellar, the skylights should be kept open during the early days to keep the temperature in the cellar stable at 0-5°C. In the later period, with the outside world cooling down the doors and windows, the temperature in the pit is controlled at 0-1 °C. Every 10-15 days, it will be checked once and the rotten ball will be picked up or listed in time. Preservation storage method: This method does not require pre-storage treatment, but it is necessary to select in advance the location of the leeward sunny, dig a good storage trench, trench depth of 0.8 meters, 11.5 meters wide, unlimited length. In the late harvest period, the roots of the plants are dug up, and the yellow leaves of the canals and the diseased leaves are planted in the storage trench. The trees are leaned against each other. After pouring enough water, the top of the ditch is erected with wooden poles or bamboo rafts. On the grass, we open the sun in the morning and keep the temperature in the ditch 17-20°C during the day and 0°C in the evening. In the later period, a plastic film is to be added to the lamb, and the soil is tightly pressed around it. During the day, the grasshoppers will be covered at night. Keep 1°C during the day and 0°C during the night. The temperature is too high, easy to form scattered flowers, the temperature is too low, vulnerable to frost damage. Therefore, during the entire storage period, the yellow leaves and diseased leaves should be inspected frequently, and they should be listed successively with the growth of flower bulbs.
