Detailed Explanation of Main Cultivation Techniques for the New Late Japonica Rice Variety Ning 81
1. Sow at the right time and transplant at the right time. Sun the seed before sowing, soak the seed with seed-soaking agent or "402" chemical solution. For single-season late rice cultivation, the sowing period is June 5-15, with a seeding rate of 2.5-3.0 kg per mu, a seedling-bed seeding rate of about 30 kg per mu, and a seedling age of about 25 days. For continuous late-season cultivation, the sowing period is June 25-30. The seeding rate is about 3.0 kg per mu, the seedling-bed seeding rate is 25-30 kg per mu, and the seedling age is 25-30 days. For continuous late-season machine transplanting or seedling-throwing cultivation, sow around July 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

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

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

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

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

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

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.

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
