There are roughly three reasons why radish appears to crunch during storage: (1) Wounds, cracks, and other wounds are caused during harvesting and shipping, which increases respiration and nutrient consumption. (2) The ambient temperature is too high. The suitable temperature for radish storage is 1-3°C. When the temperature exceeds 3°C, it is prone to bud growth, which causes the water and nutrients in the tissue to migrate to the growing point, resulting in a rapid expansion of the radish cells and a loose structure. (3) The storage environment is dry. The ideal air humidity is 90-95%, less than 90%, accelerating the transpiration of the radish itself, and dehydration to make the cell tissue soft. Before radish is stored, the above situation will be more serious if the stem plate (radish top) is not removed. For these reasons, we must take appropriate measures. First of all, try to reduce the mechanical damage such as broken skin, breakage, etc., remove the stem, place in a cool, clean place, cover tightly, prevent wind, sun and frost, and wait until the temperature in the pit or the reservoir falls below 4°C. In storage. Secondly, when storing, we should first spread a thick 8-9 cm thick wet sand on the bottom of the cellar, and then check whether the radish stem disks are clean and have no wounds. Then, a layer of radish is placed on top of a layer of wet sand, which is in turn laid out. There is no gap, and the stack height must not exceed 2 meters. Before the heavy snow, it is necessary to pay attention to ventilation and temperature control and moisturizing, so that the cellar temperature is about 2°C and the humidity is 90-95%. From the snow to the beginning of spring, the cellar temperature of 0 °C is appropriate, if you find shiny or blister radish, it shows that has been frozen, it should promptly cover straw, sacks and other cover antifreeze. After the beginning of spring, the temperature gradually rises. If it is found that the air in the pit is dry, a small amount of water should be sprayed on the radish heap to avoid the occurrence of caries. Third, if there is less stock, the radish can be cut off from the stem plate and put into the thin yellow mud to make a layer of mud. After the shade dries up, it forms a sealed mud shell, which is piled in a cool place. can. If the radish heap is covered with dry soil or straw curtains, the effect will be better.
