Having said all this, what is the modified atmosphere maintenance method, and why can it achieve the effect that other methods can't do, let's reveal the secret.
As we all know, the necessary conditions for the survival and reproduction of insect mold are that the oxygen concentration is higher than 20%, when it is lower than 20%, the eggs enter the state of suspended animation, and below 2%, the adult worms and eggs are in a state of death, and the mold almost disappears.
The main principle of the modified atmosphere is to reduce the oxygen concentration and carbon dioxide concentration in the sealed space, and create an environment that kills insects and inhibits the growth and reproduction of mold.

Generally, borers stop their activities at the ambient temperature of 8 10 and enter hibernation at -4 -8, and the temperature is lower than -4 after a certain period of time, which can kill the pest. The use of low temperature (2 10) storage of decoction pieces can effectively prevent the occurrence of deterioration phenomena such as insects, mildew, discoloration, and oil walking that are not suitable for drying and drying traditional Chinese medicine. Some valuable Chinese medicines are also mostly cured at low temperatures.
When the rainy season comes, the decoction pieces can be stored in the refrigerator, and the temperature is 2 10 is appropriate, which not only contains the grip to prevent mildew, insects, discoloration, and oil, but also does not affect the quality of medicinal materials. Because this method requires a fixed set of equipment, the cost is large, so it is mainly used for valuable medicinal materials, especially the medicinal materials that are easy to mold and moth, and the medicinal materials that have no other better way to keep them. For example, toad oil, white fungus, ginseng, chrysanthemum, yam, wolfberry, tangerine peel, etc. are also commonly used in this method.
Refrigeration is best carried out before the plum season, and can only be shipped out after the plum season, and the temperature should not be lower than 2, so as not to affect the quality of the pieces. Therefore, ABCD should be selected for this question.
