How to prevent and control licorice rust? Detailed explanation of prevention and control methods
The pathogen is a basidiomycete fungus, mainly affecting the leaves. On the underside of infected leaves, yellow-brown blister-like lesions appear on one side; after the epidermis ruptures, brown powder is released, which are the uredinia and urediniospores of the pathogen. From August to September, dark brown teleutosori form. Prevention and control methods: 1. Collect diseased plant leaves and burn them. 2. At the early stage of disease onset, spray 0.3-0.4 degrees Baume lime sulfur mixture or 97% dithianon sodium 400-fold solution.

Detailed Explanation of the Botanical Morphological Characteristics of Licorice
The licorice plant is 50-150 cm tall, with a thick, cylindrical root that often grows horizontally and tastes sweet. The outer bark is reddish-brown or dark brown. The stem is upright, mostly woody in the lower part, and the whole plant is covered with short white soft hairs. The odd-pinnate compound leaves are alternate, with 7-17 pairs of leaflets that are ovate-elliptic, entire, and covered on both sides with glandular scales and white hairs. The raceme is axillary, the calyx is bell-shaped, and the corolla is papilionaceous, purplish-red or blue-purple. The pods are mostly densely clustered in a spherical arrangement; a single pod is sometimes curved into a sickle shape, brown, densely covered with prickly glandular hairs, and contains 6-8 seeds, sometimes 2,

Detailed Explanation of Sand Storage Treatment for Licorice Seeds
If a large quantity of seeds is used, sand storage treatment is mostly adopted. The method is: carry out the treatment about 2 months before sowing. First, soak the licorice seeds in 60°C warm water for 4~6 hours, stirring several times during soaking. After removing them, drain them, and mix them evenly with clean fine river sand at 5 times the volume of the seeds. The humidity of the river sand should be such that when squeezed in the hand, water appears but does not drip. Then put the evenly mixed seeds into a wooden box, pack the surrounding area tightly with wet sand that has not been mixed with seeds, and cover the top with a 3~5 cm thick layer of moist fine river sand. Finally, place the seed box into a prepared pit,

How to treat licorice seeds? A detailed guide to the warm water soaking method
Soak the seeds in warm water at 60°C, stirring constantly. Once the water temperature drops, remove the seeds and soak them in clean water until they swell, then remove and drain them before sowing. Warm water soaking can increase the germination rate of the seeds by 15%-20%. Alternatively, soak the seeds in warm water at 60°C for 4-6 hours, remove them and place them in a warm spot, cover with a damp cloth, and rinse with clean water twice a day, then sow once the seeds crack open.

Identification and control methods of the licorice seed weevil
Morphological characteristics: The adult is oval, brown or dark brown, with a body length of 2.5-3mm and a width of 1.5-1.8mm; the antennae are broad and short, serrate, and do not reach the base of the elytra. The pronotum is covered with punctures and dense light brown hairs, and its posterior margin is as wide as the elytra. The elytra are covered with punctures and dense light brown hairs. The pygidium is long, slightly pointed at the tip, and the ventral surface is covered with dense light brown hairs. The inner margin of the hind femur has 1 small, indistinct tubercle near the tip; the inner margin of the hind tibia has 1 long tooth at the tip; the first segment of the hind tarsus is the longest. Damaged crop: licorice. Damage symptoms: main

How to grow licorice for high yield? A full breakdown of the technical key points
1. Soil selection. Choose deep soil layers, good drainage, high-lying terrain, and sandy soil and sandy loam soil with relatively high calcium content. Waste flats and waste slopes with slightly alkaline soil and a pH between 7 and 8.5 can all be cultivated. Plots with low-lying terrain and heavy clay soil must not be planted. 2. Variety selection. Choose the new "Wosheng licorice" variety suitable for artificial cultivation. This variety has the following characteristics: First, strong adaptability, drought resistance, cold resistance, salt-alkali resistance, heat tolerance, and tolerance to poor soil. Its temperature adaptation range is 43 to 45°C. In areas with severe water shortage or relatively dry conditions, no wilting or death has been found, and it can adapt to weakly alkaline calcareous soil. At the same time, it is suitable for intercropping with young forest and fruit trees; second, a short growth cycle. With seedling raising and transplanting, the seedlings grow for 3 to 4 months, and after planting they can be harvested after 8 to 10 months of growth; third, fast growth. Because of its prostrate growth habit, combined with artificial cultivation techniques, it grows horizontally at 30 cm on the soil surface, and its absorption rate of natural conditions such as light, water, and fertilizer is high, so its growth speed is fast. Thirty days after sowing, 3 to 4 true leaves appear. At 60 days, the plant height is 30 cm, the root length can reach 20 cm, and the diameter is 0.5 cm; fourth, harvesting and processing are simple. All operations can be mechanized, less labor is used, and it can be sold after being naturally dried to 80 percent; fifth, high yield and good quality. The yield of medium rough grass per mu is more than 500 kg, and high-yielding fields can reach 800 kg. The skin is red, there are few branches, and the strips are uniform. It meets the standards of the national pharmacopoeia and complies with the germplasm requirements for building a GAP production base.

Detailed Explanation of the Processing Technology and Method for Licorice-Flavored Melon Seeds
1. Ingredients: Use 5% licorice, 3% salt, and 0.05% saccharin, add water and boil into a broth. 2. Method: Wash the black melon seeds, air-dry them, put them into a wok and heat over high heat until hot to the touch. Switch to low heat, and at the same time sprinkle in the prepared broth, stirring while sprinkling, until the melon seed kernels turn yellowish.

Detailed Explanation of Control Methods for Licorice Leaf Spot Disease
① The pathogen is a type of imperfect fungus (Cercospora astragali), belonging to the subdivision Deuteromycotina → Moniliales → Cercospora fungus. It damages leaves; affected leaves produce circular or irregular lesions, with the center of the lesion grayish-brown and the edges brown, and grayish-black mold-like growth on both the front and back of the lesions. Fruiting bodies grow on both sides of the leaf, but mainly on the upper surface; the stroma consists of only a few brown cells; conidiophores are born in bundles of 6 to 12, pale brown, with the apex lighter in color and narrower, unbranched, having 0 to 5 geniculate nodes, with the apex nearly truncate, spore scars prominent, and 1 to 7 septa; conidia are whip-shaped to obclavate, colorless and transparent, straight to curved, with the base truncate to nearly truncate, the apex slightly blunt, and 3 to 10 septa.

What are the classification methods for rice bran? A detailed explanation of common types
Rice is one of humanity's main food grains, and it is rarely used to feed livestock. What is used as feed is mainly the by-product of processing rice into milled rice - rice bran - and its nutritional value varies greatly depending on the processing method. Depending on the rice processing method, rice bran can be divided into rice hulls, rice bran and rice mill by-product. Rice hulls are the hulls removed when processing rice into brown rice.
