Detailed Explanation of Key Techniques for High-Yield Cultivation of Licorice
Licorice, also known as sweet grass root, is a medicinal plant of the Fabaceae family. Its roots and rhizomes are used as medicine, and it has the effects of tonifying the spleen and boosting qi, clearing heat and detoxifying, moistening the lungs and stopping cough, and harmonizing all medicines. Licorice prefers a dry climate and tolerates severe cold. It is suitable for planting in sandy soil with deep soil layers, good drainage, a relatively low groundwater table, and rich calcium content. The soil should preferably be neutral or slightly alkaline. Waterlogged lowlands, land with a high groundwater table, and acidic soil are not suitable for planting. Licorice is generally propagated by rhizomes. After harvesting licorice in autumn or spring, the thick roots are used as medicine, and fine

Detailed Explanation of Licorice Propagation Methods and Cultivation Management Techniques
Propagation methods: use seeds, rhizomes, and division propagation. 1. Site selection and land preparation: sandy soil and loose red loam soil are suitable; apply 2500 kg of farmyard manure per 667 sq m, deep plow 40-50 cm in autumn, rake fine and level, and make high ridges with a ridge width of 40-50 cm and a ditch width of 30-35 cm. 2. Seed propagation: because licorice seed coats are hard and thick, making emergence difficult, before sowing mix crushed glass with an equal amount of seeds and grind for half an hour, giving a germination rate of about 85%; or use 3 times the seed volume of

Key Points on Harvesting and Processing Techniques for Licorice (Part Three)
For licorice propagated from seed, harvest in the 4th year; for licorice propagated from rhizomes, harvest in the 3rd year. Harvesting can be done either before Grain in Ear (Mangzhong) or after White Dew (Bailu), but harvesting after White Dew is preferable. After digging them up, cut off the branches and twigs while fresh, sun-dry until half dry, tie into small bundles separately according to thickness, and sun-dry until completely dry. Quality specifications for dry goods: cylindrical in shape, thick at the top and thin at the bottom with no reed head, surface purplish-red or grayish-brown, rough skin, loose and light in texture, cross-section yellow-white, starchy, sweet in taste, free from impurities, insect damage, and mildew. Grade One: length over 60 cm, diameter over 1

Detailed Guide to Harvesting and Processing Licorice Root (Part Two)
For seed propagation, harvest after 3 to 4 years; for rhizome and division propagation, harvest after 2 to 3 years. Digging can be done from late autumn to early winter and before spring sprouting. Those dug in autumn are the best, with a high glycyrrhizic acid content and a firm texture. After the licorice is dug out, clean off the soil, remove the stem base, branches and fibrous roots, cut into sections of appropriate length, sun-dry until half dry, tie into small bundles, then sun-dry until completely dry.

Detailed Explanation of Licorice Harvesting and Processing Methods (1)
Key Technical Measures for High-Yield Cultivation Choose fertile, loose-textured, well-drained sandy loam soil for planting. Treat the seeds before sowing to improve the germination rate, water the seedlings to keep them alive, and apply sufficient phosphorus and potassium fertilizer every early spring. Harvesting and Processing 1. Harvesting Licorice propagated from seed generally grows for 4 years after sowing, while that propagated from rhizomes can be harvested after 3 years of growth. Harvesting in autumn each year is best. When harvesting, dig up the licorice roots and rhizomes, shake off the soil, and set them aside for processing. 2. Processing Method Dig

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

Research and Development Progress of Functional Rice and Its Food Products
Functional rice refers to rice products that regulate human physiological functions, are suitable for consumption by the general population, and are not intended for the treatment of diseases. In addition to containing the seven major nutrients necessary for human growth and development - protein, fat, carbohydrates, vitamins, minerals, water and fiber - functional rice also contains certain special components that regulate and balance human physiological functions. It can enhance physiological defense mechanisms, prevent specific diseases, delay aging, and control physical strength and energy status. 1. Processing of functional rice

Introduction to the Characteristics of the Zhendao 2 Rice Variety
Zhendao 2 was developed by the Zhenjiang Institute of Agricultural Sciences from a variant plant selected from "Guihua Nuomi" (Osmanthus Glutinous Rice), and belongs to the late-maturing medium glutinous type. When grown as single-season rice, it is sown in mid-May, reaches full heading in mid-August, and matures in mid-October, with a total growth period of nearly 150 days, a total leaf age of 16-17 leaves over its life cycle, and 5-6 elongated internodes. When transplanted after melon, rice, or beans, it reaches full heading in early September and matures in late October, with a total growth period of about 125 days, a total leaf age of about 14 leaves over its life cycle, and 4-5 elongated internodes. It has large panicles with many grains and a high seed-setting rate. For a yield of about 600 kg per mu, the yield structure is

Detailed Explanation of Super-High-Yield Cultivation Techniques for Single-Season Rice in Northern China
(1) Use plastic film and special non-woven fabric to cover dry-raised rice seedlings, with the seeding rate controlled within 200 grams per sq m. (2) Transplanting spacing in the paddy field: 30 cm x 16.7 cm to 20.0 cm sparse planting, or (40 cm + 20 cm) x 16.7 cm wide-ridge double-row sparse planting. (3) Apply 60-70 kg of standard nitrogen per mu, 10 kg of diammonium phosphate, and 10 kg of potassium sulfate. (4) Intermittent water-saving irrigation in the paddy field alternating shallow water, wet, and dry conditions. (5

Detailed introduction to the new conventional rice variety Aixianzhan
Aixianzhan, a new conventional rice variety bred by crossing Yueyezhan 21/Yuanxianzhan, is a high-quality, high-yield conventional rice variety suitable for both early and late seasons. It was identified as Grade 1 high-quality rice under the national standard through physical and chemical analysis by the Food Quality Supervision and Inspection Testing Center of the Ministry of Agriculture (Wuhan), breaking the zero record for new rice varieties of Grade 1 high-quality under the national standard in our province. It is reported that this variety is a temperature-sensitive indica rice with medium maturity in the early season and early maturity in the late season. In the 2002 late season, it participated in the provincial regional trial, with an average yield of 383.29 kg per mu, an increase of 3.54
