Licorice should not be stored for too long
Licorice storage is generally wrapped in compressed linen packaging, each 50 kg, stored in a dry, ventilated place, the safe moisture content of the commodity 12%~14%. There are more than ten kinds of pests in licorice warehouse, such as coffee bean weevil, domestic antler longicorn, four-star longicorn, etc., which can be treated with nitrogen or carbon dioxide for 514 hours, and all adults and larvae can die. There is no obvious change in licorice endoplasm.
Licorice is easy to mold, if the air humidity is too large, licorice surface is easy to produce mildew spots or white and green hyphae, the following measures can be taken to prevent and control: water content to ensure that 14% below, environmental relative humidity control in 80% below, good packaging seal, the use of pile position and account to wet; chemical fumigation, with 10000:1 ratio of Cubeb volatile oil, sealed fumigation for 6 days, its mold content will be greatly reduced.
The storage life of licorice should not be too long. Some people have studied licorice in different storage periods and found that storage time has a direct effect on the content of licorice, which decreases with the extension of storage time. The storage time of licorice for 1 year is 5.12%, 2 years is 4.24%, and 3 years is 3.08%. It can be seen that the longer licorice is stored, the greater the loss of effective ingredients. Therefore, licorice products should be sold as soon as they are collected, and should not be stored for too long.

Harvesting and processing of licorice
Harvesting and processing licorice is generally planted for 1-4 years. Hebei, Beijing planting 1-2 years harvest, Inner Mongolia; Northeast, * planting 3-4 years harvest. At present, there are two cultivation methods, one is direct seeding, the other is raising seedlings in the first year, transplanting in the second year, transplanting horizontally in the ground, easy to harvest. The first method is simpler and less gardener, and the second method is suitable for small family planting and intensive cultivation. Planting in a large area and harvesting is a problem, and manual digging is very difficult. After years of experiments, we can use the 55 iron cow rubber wheel tractor.

Licorice is not difficult to grow.
At present, there is a great demand for licorice products at home and abroad. Experts believe that to solve the contradiction between the demand for licorice products and environmental protection, the most important thing is to develop licorice artificial planting industry. Judging from the actual situation of artificial cultivation of licorice at present, it is feasible to promote the coordination of planting and fence culture and to reasonably develop the construction of the base. In fact, licorice is not a difficult plant to grow, as long as the soil and water are suitable, it can be planted on a large scale. Some people think that the key to solving the problem of artificial planting of licorice is not money.
