After the radish has been harvested, there is no period of physiological dormancy. In the storage process, budding pods occur under suitable conditions. The growth of the pods and leaves consumes the moisture and nutrients of the fleshy roots, and the breathing continues, resulting in an increase in radish fibers, glutinousness, and Natural weightlessness. In winter, radish can be stored by means of a ditch method, which can generally be stored until the following year from March to May. The storage period can be as long as six months. The green radish has a long shelf life and can be stored until the following May; the red radish is the next, and the storage period is 3 to 4 months; the white radish is poor and can only be stored for a short time.
It is best to dig trenches in trenches with low groundwater levels and good water retention. Low temperature in the shade, small changes in temperature, and slow temperature increase in spring, which is conducive to prolonging the shelf life of radish. When radishes are stored in large quantities, they are mostly buried in open, airy fields. The storage ditch is generally east-west direction, and the upper earth mound is dug out on the south side of the ditch, blocking the sun, leaving little dirt on the soil, and is placed on the north side of the ditch, and is then used for covering. If the ditch is dug on the north side of the building, both east-west and north-south ditch can be used. The ditch is about 60 centimeters deep and the ditch is 0.8 meters to 1.5 meters wide. If the ditch is too deep, the temperature at the bottom of the ditch is high; if it is too shallow, the cover soil is too thin and it is prone to drought and freezing, which is not conducive to long-term possession. The length of the ditch is determined by the amount of storage. Generally, a 1 meter long ditch can store 225 to 250 kilograms of radish. When digging trenches, ditches with a width of 10 to 13 cm and a depth of 12 to 20 cm should be dug along the ditch at the bottom of the ditch. Both ends of the ditch should lead to the ditch, and then horizontally dig a horizontal ditch every 60 to 100 cm. , intersecting with the longitudinal groove is "10" shape, the mouth of the groove out from the side wall.
As soon as possible, the radish stored in trenches will not be exposed for a long time. Move to avoid collision damage, so as not to blacken the wound decay. It is better to enter the ditch before 10 o'clock in the morning, when the radish temperature is low, the amount of heat brought into the ditch is small. Before the storage, dig up the growing point, or just go to the leaves, and cut the tops later in the storage period. When storing, put a layer of radish to cover a layer of soil, so that each radish is surrounded by wet soil, so that it can maintain moisture, reduce disease, storage effect is good, and the effect of stacking with wet sand is better. The thickness of the stack is preferably 40 to 50 cm. If the thickness of the stack is too thick, the temperature difference between the upper layer and the lower layer is too large, and the upper layer may become frozen and the lower layer may become hot.
The optimum temperature for storing radish in stages is 1～3°C. If it is higher than 5°C, it will germinate easily. If it is less than 0°C, it will be rotted. During storage, the thickness of the cover soil should be increased or decreased according to the weather. The temperature at the early stage of storage is high and the cover soil is thin. With the temperature decreasing, the thickness of the cover soil is increased in time to make the thickness of the cover soil close to the thickness of the frozen soil layer. Covered soil should be wet, especially the soil around the radish must be wet, and water should be properly watered when the soil is dry. After pre-storage and after the spring, pay attention to adjust the temperature, timely treatment of frozen, rotten and sprouted radish.
When storing radish, the key is to create a low-temperature, humidity-friendly environment so that the radish grows and respires without losing water. The greenhouse radish produced by the greenhouse can be stored according to the above method. If the temperature is higher at the time of harvesting, it can be pre-cooled in the shed or outside the shed after harvesting (the temperature should not fall below 0°C to avoid freezing) and then be stored in the ditch. The individual flowers and radishes are small in size and should not be stacked too thick during storage. It is best to layer them together with fine sand or fine soil and consider that they can be easily removed after storage.
