What are the characteristics of licorice's growth habits?
Licorice, also known as "sweet grass seedling", is a perennial herbaceous medicinal plant. Licorice prefers an ecological environment with ample sunlight, low rainfall, scorching summers, severe cold winters and large day-night temperature differences, and has the characteristics of being light-loving, drought-tolerant, heat-tolerant, salt-alkali-tolerant and cold-tolerant. It is suitable for growing in sandy soil that is deep, loose and well-drained. Licorice seeds have a thick and hard seed coat with poor water permeability, making them difficult to germinate; seed treatment is required before sowing, and the treatment method is to use coarse sand and a rice mill to abrade the seed coat, making it rough and increasing water permeability.

Licorice Star Fruit
This product belongs to the preserved fruit category. The raw material used can be dried star fruit or salted star fruit pips. The processing technique is as follows: 1. Raw material handling: Dried star fruit should be soaked in water for about 1 hour, the purpose being to let the dried product rehydrate to a semi-dry state so that it can rapidly absorb the liquid. If it is a semi-finished salted pip, it should be soaked in water for desalting; the desalting degree can retain 1-2% salt content, then take it out and dry it to a semi-dry state for later use. 2. Liquid preparation: 10 kg of dried tangerine peel, soak in a large amount of clean water to remove the bitterness, or boil for 10 minutes and then soak in water,

Processing Methods and Technical Key Points for Licorice Waxberry
Licorice waxberry is a type of preserved fruit product, and the raw material waxberry is utilized in the form of its finished salted blank. Its processing technology is as follows: 1. Raw material handling: The process of turning fresh waxberry into a semi-finished product is as follows. Cure with 20% salt, one layer of fruit and one layer of salt. Add another layer of salt on top. After curing for more than ten days, scoop the raw material out of the brine and sun-dry it until salt frost appears, which is the semi-finished salted blank. Further process from the salted blank. First, desalt by soaking in water to remove the overly salty taste; the degree of desalting generally leaves about 2% salt, and there is no need to remove the salt completely.

How to control licorice aphids? Master these methods
They damage tender leaves, tender shoots, flowers and fruits. Adults and nymphs suck plant sap; in severe cases they can cause leaves to turn yellow and drop, affecting seed set and marketable yield. Control methods: ① Avoid planting next to leguminous plants. ② During the occurrence period, spray with 40% dimethoate emulsifiable concentrate at 1000 times dilution.

Detailed Guide to Seed Selection and Seed Treatment Methods for Licorice
Seed selection: Ural licorice (Glycyrrhiza uralensis), which has higher levels of glycyrrhizic acid and glycyrrhetinic acid, was chosen. Seed treatment: licorice seeds have a hard seed coat that is impermeable to water and air, making them difficult to germinate. Untreated seeds have a germination rate of only 30%-40%, while seeds treated by breaking the seed coat can reach a germination rate of over 90%, so the seeds must be pre-treated before sowing. The method used is: soak the seeds in water at 60°C, then remove them, cover them with a damp cloth for 4 hours to 6 hours to let them absorb water and swell, then air-dry and drain them before sowing.

What are the control methods for licorice rust disease?
① Pathogen The pathogen of licorice rust (Uromyces glycyrrhizae) belongs to Basidiomycota → Teliomycetes → Uredinales → Pucciniaceae → the genus Uromyces. ② Disease pattern a. Urediniospore stage In the seedling stage of licorice, infected plants show a light brown uredinium at the tip of leaves that have not yet unfolded. As the young leaves flatten and grow, the spore masses appear densely along the leaf tip and the underside of the leaf, and finally the entire underside of the leaf is covered by spore masses, appearing as a sheet of yellow rust color; generally all leaves of the whole plant become diseased, and diseased plants are noticeably dwarfed.

Symptom Identification and Control Methods of Licorice Rust
Latin scientific name: Uromyces glycyrrhizae Magn. Crops affected: Licorice. Symptoms: Mainly affects leaves. After seedlings emerge in spring, round, grayish-white small blister spots appear on the underside of leaves, and later the surface ruptures to reveal yellow-brown powdery masses, which are the pathogen's uredinia and urediniospores. In the late stage of the disease, the entire leaf is covered by uredinia, causing the aboveground part of the plant to die; the phloem tissue at the junction of the stem base with the root or stem proliferates, latent buds sprout, and the plant becomes clustered and dwarfed. After reinfection by urediniospores,

The papilionaceous corolla is pale purple. The pods are flat, sickle-shaped or curved into a ring, densely covered on the outside with bristle-like glands. The flowering period is June to July, and the fruiting period is July to September.
