Morphological characteristics of Glycyrrhiza uralensis and suitable seed environment
[Morphological characteristics]
Licorrhiza is a perennial herb, 30~100 cm high. The whole body is covered with white pubescence and glandular hairs. Above-ground stem erect, lignify below, branchlet has angulate, green. The leaves alternate and are odd-numbered compound leaves. Leaflets 3~8 pairs, oval or ovate-elliptic, entire margin, apical leaflets larger. Racemes, axillary, pedicels very short, with an ovate bracteole below base, calyx campanulate, green, corolla butterfly, violet or blue purple flower. The fruit is a pod, narrowly rectangular, curved into a sickle-shaped or semi-annular, brown, densely spiny tomentose. Seeds 5 - 8, oval and slightly flat, smooth surface, brown.
[Suitable environment]
Licorices are light-loving, cold-resistant, drought-tolerant, barren and resistant to low temperatures of-10℃. Because licorice is a deep-rooted plant, the place with high groundwater level is not suitable for growth, and it is easy to cause rotten roots and dead seedlings. Sandy loam soil is good, clay soil and poor drainage of the low concave land is not suitable for cultivation of licorice.

Rust control of licorice
The pathogen is a kind of basidiomycetes in fungi, which mainly harms leaves. The yellow-brown blister unilateral disease spot appeared on the back of the susceptible leaf, and the brown powder was released after the epidermis ruptured, that is, the summer spore pile and summer spore of the pathogen, and the dark-brown winter spore pile was formed from August to September. Prevention and control methods: 1. The leaves of the diseased plants were burned. two。 At the initial stage of the disease, spray Baume 0.3-0.4 stone sulfur mixture or 97% diazepam sodium 400-fold solution.

Field management of licorice
In the year of direct seeding between seedlings and fixed seedlings, the height of seedlings is about 6 cm, the distance between plants is 10-15 cm, and the distance between plants is kept at 30 cm in the second year. After planting licorice by mid-ploughing, weeding should be done diligently in the first year and the soil should be loosened in time. To loosen the soil from shallow to deep, herbicides can also be used to control weeds. By the second year, when the plant grows up, it is difficult for weeds to grow and can no longer be weeded by intertillage. During sowing or planting, in addition to applying base fertilizer, phosphorus and potassium fertilizer can be applied in early spring and plant ash or compost per mu during the annual growth period.
