(2) The cellar of cabbage is fully air-dried after the cabbage is harvested to minimize the water content in the body. After the dish is dried, it can be pre-cooled and can be pre-cooled. Each dish can be 6-7 layers, and the dome can be covered with leaves. In order to avoid freezing, in the pre-cooling process to pay close attention to repair, remove the yellow leaves, remove the mud. When entering the pits, the same as the pre-cooling, according to the size and needs of the pits, according to a certain arrangement of stacking up, after entering the pits to enhance ventilation, the skylights and cellar doors are open, in late November to block the cellar doors, only use Sunroof ventilation, gradually reduce the amount of ventilation after entering in December, stop ventilation at night, when the temperature outside the pit is lower than -10 °C, when the temperature is high at noon on sunny days, conduct a short period of ventilation, discharge the temperature inside the pit, the second year 3-4 In the month, when the temperature outside the pit is higher than the cellar temperature, the cellar doors are opened in the evening to increase the ventilation and extend the ventilation time, but no ventilation is allowed at noon. The suitable temperature of Chinese cabbage during the entire cellar period is 0-2°C, and the suitable humidity is 85%. During the cellaring period, it is necessary to frequently pour vegetable pods, remove yellow and rotten leaves at the same time, and pour it about 5-6 times before and after.
(3) Cabbage and Cabbage Storage Cabbage and cabbage are basically the same requirements for storage conditions, therefore, similar to the Cabbage trench cellar also applies to cabbage, but Cabbage is more tolerant of low temperature than cabbage, the beginning of its storage and harvest period than cabbage In the evening, leave part of the green leaves at the time of harvest, and it can not be removed when it is stored. When the groove is covered, the grass should be thin and not thick, and the cover should be too late, as long as the cabbage is not too cold.
2, radish and carrots storage and preservation technology Radish and carrots are one of the most traditional storage vegetables for farmers in our county. The main storage methods are sewerage and cellar storage, and sewerage is particularly common.
(1) The radish and carrots in the ditch of radish and carrots should be harvested in a timely manner. Cut stems and discs and store them in time. The location of the sandy soil is selected in the ditch (storage). The ditch is 1.2 meters deep along the east-west direction and the ditch is 50 cm wide. The length and width are determined according to need. The mound first dug out is on the south side of the ditch and the soil dug out later. The heap is on the north side of the ditch and reserved for coverage. When radish and carrots are in the ditch, stratification is used to layer the radish and carrots layer by layer, then lay a layer and then cover the soil, but the number of layers should not be too much. The average ground temperature of radish in 1-3 months It is advisable to keep it at 0-3°C. The covered soil is required to be moist, and when it is dry, it can be sprinkled with a small amount of water. The cover soil must be divided into several times as the temperature drops, and it cannot be overburdened once to cover the radish and carrots. Keep the temperature as low as possible. During storage, we must pay attention to cover the radish with the soil on the north side of the ditch, because the bottom soil pests and diseases, can reduce the chance of infection on the radish, and the temperature and humidity are more appropriate; and the mound on the south can be used to block direct sunlight ditch The role of the mound is higher and the effect is more pronounced.
(2) The cellar of radishes and carrots is also a radish or carrot in the cellar or placed in a layer, covered with sandy wet soil, then put a layer of radish and then cover the soil, pits the last layer of radish, with wet The soil is sealed tightly, and the ventilating vents in the pits and ventilates can be properly ventilated and ventilated during the early and late periods. The temperature and humidity conditions of the entire pit storage period are consistent with the trench storage requirements.
3. Storage and Preservation Technology of Celery (1) Storage under Micro-frozen Harvest the celery under root shovel, remove the rotten yellow leaves and rotten leaves, and tie each 5kg into one for storage. Underground storage trenches are also used. The depth of the ditch is 1.0-1.4m and the width of the ditch is about 1m. The length of the ditch depends on the storage capacity. The storage volume of celery is generally 25-30kg/m3. Storage trenches are good for sand and land. If the temperature is below -5°C after harvest, the celery can be stored directly in the ditch. If the temperature is high, it should be stored in shade and stored until the temperature drops below -5°C. Then move the celery into the ditch. Turn the celery down and have a good code. When the temperature at the beginning of the ditch is relatively high, soil cover is not needed for the time being, and temporary shade can be provided by straw or corn stalks. When the ground temperature drops to -7 to -9°C, thicken it with corn stalks, etc., so that the general day and night will no longer be opened. When 1/4 of the celery in the ditch begins to show freezing performance, immediately take off the temporary covering and begin covering the soil, according to the temperature changes in different times to ensure that the storage trench temperature is maintained at -2 - 0 °C, with this method can be Storage celery 60-70 days.
(2) For the prosthesis storage, the celery should be harvested by rooting, and the individual plants or bundles of 1-2kg bales should be planted on the ground in the ditch, pit or greenhouse, and the soil should be watered according to the humidity to maintain a certain humidity. To avoid loss of celery caused by freezing or fever.
