The volcanic powder is produced in the administrative area of ​​Datang Town, Qujiang District, Shaoguan City, Guangdong Province. It is a high-quality pink cultivar in Datang Town, Qujiang District. It enjoys a good reputation in northern Guangdong and is a natural green health food. It grows in the volcanic area of ​​Datang Town, so it is called volcanic powder.

Technical requirements for quality of volcanic powders (1) Sources. Local powder Ge local varieties. Choose the middle stem section that is disease-free, stout, and full of buds to make seedlings. (2) Site conditions. Choose a soil type that is clay, convenient for irrigation and drainage, loose soil layer, and uniform texture. The organic matter content is ≥2.84%, the pH value is 4.26 to 6.05, and the soil layer thickness is ≥60 cm. (3) Cultivation management. 1. Cutting rod selection: At the time of harvesting, choose robust and disease-free branches as seedlings, and put them in a cool dry porch. 2. Seedling: From February 1st to February 10th, the middle part of the rattan of the seedlings is cut into 2 inches of buds containing two buds before planting, and the organic matter is inserted at a density of 3×3cm. 4%, nutrient soil thickness ≥ 10cm on the seedbed. After transplanting, cover the nutrient soil from 1cm to 1.5cm, cover the nutrient soil, sprinkle water and wet it, cover the straw, and remove the straw after the seedling grows. 3. Colonization: From March 5th to March 10th, the seedlings will be inserted directly into the soil, and the depth will be based on the buds just attached to the ground. Planting 1000 to 1100 plants per 667 m2 (mu), row spacing 1.2 m to 1.6 m, plant spacing 0.4 m. 4. Fertilization: Increase the application of decomposed home fertilizer, apply ≥500kg per 667 m2 (mu). 5. Plant adjustment: From April 5 to 10, a fence is inserted between the two plants, with a height of 2 m, and 600 to 800 hedges per 667 m2 (mu). Choose a strong seedling to leave, and the rest of the weak seedlings are removed, and the vines are placed on the fence. From June 5th to 10th, the ground at the base of the plant was excavated to expose the head of the genus Pueraria, which was exposed to the sun, and the buds of the geese were selected, and one or two pieces of georgae were selected. (4) Harvesting and storage. In early December, when most of the leaves of the pink gems turn yellow, they choose to harvest in sunny days. The storage method uses the soil burial method, and the powder gems are arranged neatly under the straw shed, and covered with soil for about 10 cm. Pay attention to keep the soil moisture at 35% to 65% during storage and the storage period should not exceed 6 months. (5) Quality characteristics. 1. Sensory features: long strip shape, no split ends, fleshy milky white, soft and tender taste, with 糯 (sticky), sweet taste, no residue, no odor. 2. Physical and chemical indicators: on a dry basis, protein ≥ 2.49%, soluble solids ≥ 8.8%, crude fiber ≤ 1.07%, starch ≥ 30.8%, moisture ≤ 58.4%. 3. Safety requirements: Product safety indicators must meet the relevant regulations of the state for similar products.
