Due to its high quality and high medicinal value, Jiuzi River has a high reputation in the international market because many countries in Southeast Asia regard it as a premium beverage.

Jiuzi Hehe quality technical requirements (1) site conditions. The altitude is between 300 and 1000 meters, and the soil is yellow brown soil dominated by woodland soil. The soil pH is 4 to 6.5. (2) Variety. It is the sclerotium of the Polyporaceae fungus 茯苓Poria cocos (Schw.) Wolf. (3) Cultivation management. 1. Preparation before planting: (1) Seed preparation: The pure mycelium isolated from the fresh sclerotia of Jiuzi River is used as a parent species, and is expanded into original species and cultivars for production. (2) Preparation: From the end of October to February of the next year, middle-aged pine trees with growth of 15 to 20 years and breast diameter of 10 to 20 cm are selected as culture materials. Cut down the selected pine trees, dig out the tree stalks, and cut the bark of about 3 cm in width from the longitudinal direction of the shovel, so that the trunks are irregular octahedron shape, which causes the trees to dry, that is, "skin peeling Reinforcement". After the tree is slightly dry, gather the trunk and saw it into a 50cm piece of wood. The stacking is overhead and the sun is dry. (3) Preparing for the field: Select a wasteland with a slope of less than 25°, no crops, or no plantings within 3 years. Digging in the winter, the depth is not less than 50cm, and the mud and clods in the field are broken, and the weed roots and stones are removed to freeze the sun to eliminate the bacteria and eggs. 2. Inoculation and colonization: In mid-May, select the sunny day for inoculation, 1 bag for each strain, and about 8kg for the culture. Usually, the culture material is placed in two layers, and the strain is inoculated tightly on the cross section of the culture material. Then cover the soil and seal it. 3. Inoculation "inducing": About 20 days after inoculation, when the mycelium grows to the end of the culture material, the sand around it is opened, and a piece of freshly prepared fresh weight of about 50g to 80g is inoculated. Sclerotium block (ie "inducing"). 4. Field management: Jammu → Qinggou drainage → Covering soil cover → Fence protection field 5. Pest control: The common disease of alfalfa cultivation is sclerotial soft rot, and the insect pest is cockroach. Generally, the correct selection of the field, the investigation and the replacement of the method are adopted to carry out harmless comprehensive treatment. 6. Harvesting (starting): Harvesting can be carried out half a year after planting and planting. From November to December of that year, there will be no new cracks on the surface of the open field. The barrel will change from light yellow to brown, sclerotia. The epidermis has no white growth cracks and is slightly hard to the touch. Choose sunny days when harvesting, and keep the sclerotia intact to avoid damage to the outer skin. (4) Processing. The process of processing is: after the fresh sorghum is harvested, the sand is removed → the categorized → sweating → peeling → cutting (white, red separated) → sun drying to 60% dry → returning → sun drying or drying to dry → Grading → Inspection → Packaging. 1. Pre-processing: Place fresh sclerotia (tidal) in a clean, dark, closed room (sweating room), sort and stack according to individual size, cover with clean straw, and turn once every 4 to 5 days. The water in the fresh sclerotia is evenly and slowly escaped, and after 10 to 15 days of "sweating" treatment, the surface of the fresh sclerotium is slightly shrunk and dry, and the skin is peeled off after being removed. 2. One processing: one consists of fresh and dried ones. (1) Fresh squid is a mature and complete fresh sclerotium, which is irregularly spherical, with a light brown to tan surface, slightly rough, and can be seen to have healed growth cracks. The cross section is white with more juice and mild taste. , chewing the sticky teeth. (2) Dry sputum is fresh and dried by repeated sweating. The surface is brown, dark brown, with tumor-like wrinkles, firm weight, white cross section, light taste, chewing sticky teeth. 3. Block processing: The block is cut and dried by fresh peeling, which is in the form of blocks and varies in size. 4. Bran processing: The bracts are cut, planed and dried from freshly peeled, and the flakes are in the form of flakes with a thickness of ≤0.2cm. (5) Quality characteristics. 1.
