Harvest Time and Processing Methods for Licorice
The harvest time is generally late autumn to early spring, and it is best after the leaves have fallen and withered in autumn. The licorice roots harvested at this time are firm in texture, heavy in weight, high in powder content, and strong in sweetness. Remove the soil from the dug-up licorice (washing with water is strictly prohibited). While still fresh, use a fodder chopper or a sharp knife to cut off the branch roots from the head and root portions close to the main root. Divide them into first and second grades according to the diameter of the root head, and mao cao. Generally, dried goods with a thick head diameter of more than 1.5 cm are first grade, those with a diameter of 0.3-1.4 cm are second grade, and those smaller than 0.5 cm are placed in mao cao. For first and second grade licorice, the root strips must not be shorter than

Asexual Propagation and Seedling Methods for Schisandra: A Detailed Guide to Layering Techniques
Layering is one of the oldest propagation methods created by the working people of our country. Its characteristic is that a portion of a branch still attached to the mother plant is bent down into the ground, causing the branch to root and produce a new individual. Its advantages are that the seedling has ample nutrients during the growing period, is easy to survive, grows vigorously, and bears fruit early. Layering is mostly carried out after sprouting in spring, when the new shoots have grown to about 10 cm. First, beside the mother plant intended for layering, dig a 15-20

Field Management Methods and Technical Key Points for Schisandra chinensis
(1) Trellis management: During the young stage, the selected main vines should be tied to bamboo poles in time to promote upward growth. In principle, new shoots sprouting from the lateral vines of mature trees do not need tying; if any are too long, they can be pinched at about 8-10 nodes. If the lateral vines (fruiting mother branches) are left too long or carry a heavy load, necessary tying should be given to prevent branch breakage. (2) Cultivation and weeding: more than 5 times a year, at a depth of about 10 cm, keeping the soil loose and free of weeds within the planting strip. Deep plowing is carried out throughout the whole orchard after fruit harvest.

Seed propagation methods and key technical points for Schisandra chinensis
1. Seed treatment: From late August to mid-September, harvest ripe fruit, rub off the peel and flesh, float off shriveled seeds, and dry in a cool place. In mid-to-late December, soak the seeds in clean water for 3-4 days, changing the water once daily, then mix the wet seeds with clean fine river sand at a ratio of 1:3. The sand moisture is usually kept at the level where it forms a ball when squeezed tightly in the hand without dripping water (absolute moisture content of about 40%-50%). Place in a wooden box or flower pot for storage, keeping the temperature at 0-5°C. In Northeast China, before the soil freezes,

Detailed Explanation of Fertilization and Watering Methods and Technical Points for Schisandra chinensis
(1) Watering and Fertilization. Schisandra chinensis (five-flavor berry) prefers fertilizer and needs sufficient water and nutrients during the growing season. After planting and establishment, water frequently to keep the soil moist. Irrigate once before the ground freezes to aid overwintering. During the bud differentiation, flowering and fruiting stages, in addition to sufficient water, large amounts of nutrients are also needed. Apply chemical fertilizer twice a year: the first application during the leaf expansion stage, with quick-acting nitrogen and potassium fertilizer. The second application after the plants flower (mid-growth period, early July), with quick-acting phosphorus and potassium fertilizer. As the plant grows larger, the fertilizer amount increases year by year: ammonium nitrate 25-100 g/plant, superphosphate

Planting Methods and Management Techniques for Schisandra chinensis Seedlings
The planting methods for Schisandra chinensis seedlings and the management techniques after planting directly affect the survival rate of the seedlings and the growth condition of the plants, and are also an important foundation for whether early cultivation of Schisandra chinensis can achieve high and stable yields. In recent years, with the continuous expansion of Schisandra chinensis cultivation area, people have summarized some relatively mature experience in the planting of Schisandra chinensis seedlings and post-planting management techniques, which are briefly introduced as follows: 1 Planting and management of finished seedlings 1.1 Planting period Schisandra chinensis finished seedlings can be planted in autumn or spring. Autumn planting is carried out before the soil freezes;

Why Does Schisandra Drop Its Flowers and Fruit? Causes and Control Methods
I. Causes of flower and fruit drop 1. Low-temperature freezing damage causes flower drop. In some areas of the east, the last frost period occurs in mid-May, and cold air masses cause physiological chilling injury, causing some flower buds to drop. 2. Herbicide drift causes flower drop. Field herbicides are mostly used in late April and early May, which is exactly the flowering period of Schisandra. Herbicide drift directly damages Schisandra petals, preventing female flowers from pollinating normally and causing flower drop. 3. Pests and diseases cause fruit drop. The main diseases are root rot, leaf blight, and powdery mildew, which cause fruit drop when they occur severely;

Detailed Explanation of Schisandra Breeding Techniques and Methods
Schisandra is a plant of the Magnoliaceae family and a valuable medicinal material, with effects of astringing the lungs, nourishing the kidneys, stopping sweating, stopping diarrhea, and securing essence. Schisandra prefers humid environments (but is not tolerant of low-dust waterlogging), is cold-resistant, needs moderate shade, and is suitable for humus soil or loose, fertile loam. It has strong adaptability and can be planted in both northern and southern China. It often grows wild in mixed coniferous and broad-leaved forests, mountain gullies, along stream banks, among small trees and shrubs, or at forest edges and open areas within forests. Breeding methods for superior varieties: 1. Seed propagation. After autumn, collect the fruits, remove the fruit

Occurrence and Control Methods of Powdery Mildew in Licorice
The pathogen is a type of imperfect fungus among the fungi, with the scientific name Erisiphepolygoni. It damages the leaves, and diseased leaves develop white powdery growth on both the upper and lower surfaces. For control, spray 0.2-0.3 degrees Baume lime sulfur mixture.

Identification of Symptoms and Control Methods for Powdery Mildew on Licorice
It mainly damages leaves, and can also damage pods. The surface of affected leaves and pods is covered with a layer of white powder, and later many small black spots appear on the lesions, which can cause early defoliation or wilting of the whole plant. Control methods: spray 0.1-0.3 degrees Baume lime sulfur mixture, 50% thiophanate-methyl wettable powder 800 times dilution, 50% amobam 600 times dilution.
