Study on the ecological environment of licorice growth by using plant growth room

Licorice is not a weed on the roadside. It has a high medicinal value. With the continuous research and development of licorice, the value of licorice is increasing. However, the demand for licorice is increasing. As for the wild licorice resources, the growing licorice is growing. So what is the licorice suitable for growing under what conditions? In the process of artificial cultivation of licorice, some scholars have found that the application of plant growth chamber can provide suitable growth conditions for licorice, and it is expected to make up for the shortage of wild licorice resources. Under natural conditions, licorice seeds have high hard solid rate and low germination rate, which directly affects the planting efficiency of licorice. The seeds of licorice are small, the seed coat is dense, and the water permeability and permeability are poor. The mature seed seed rate is as high as 96.15%, and the seed germination rate is extremely low, which seriously affects the emergence rate. The germination temperature of plant seeds is closely related to the climate and habitat conditions of plant populations, and it is an adaptation of plants to the natural environment. During the germination process, the seed germination temperature has the optimum value, that is, the optimal germination temperature. At 10 °C and 15 °C, the germination rate of licorice seeds tends to be stable from 6 to 7 days, and the other temperature germination rate tends to be stable at 5d. The germination rate of Glycyrrhiza glabra seeds is the highest, the optimum temperature for germination speed is 15~40°C; the optimum temperature for germination speed of Ural licorice is 25~30°C; the germination rate of licorice seeds is always low, and the highest germination rate is only 35 %, the temperature at this time is 35 °C. That is to say, in the actual artificial culture process, because of the different varieties of licorice seeds, the germination conditions of licorice seeds are also different, which often requires the use of plant growth chambers to simulate and adjust the cultivation conditions suitable for different varieties of licorice seeds, in order to improve the artificial cultivation of licorice.
