Longquan Ganoderma lucidum spore powder quality technical requirements (A) strains. Local screening, domestication and cultivation were carried out. After 2 years of Ganoderma lucidum stage wood cultivation test in Longquan, it was confirmed by the strain management department that the species was suitable for local cultivation and had high medicinal value. (2) Cultivation substrate. 1. Matrix requirements: broad-leaved tree logs, preferably 8cm to 20cm in diameter. 2. Deforestation time: The trees are deciduous until they are germinated. 3. Segment wood processing: Logs are stored in a cool place, cut off 15 to 30 days after felling, and the length of cut off should be 28cm to 30cm. 4. Selection of Shibachang: The altitude should be 300m to 600m. It is located in a flat, open and ventilated sunny place, with loose soil, convenient drainage and no flood disasters. (3) Production technical requirements. 1. Culture of strains: The culture medium should comply with the relevant regulations of the industry and local regulations on the management of edible fungi. 2. Sterilization: The feed temperature is 98 ° C to 100 ° C and continuously maintained for 10 h to 12 h. 3. Inoculation: Two inoculations are carried out when the temperature of the segmental wood after sterilization is ≤30 °C and the temperature is ≤25 °C. 4. Culture: culture at a temperature of 15 ° C to 30 ° C for 90 days to 110 days. 5. Management of Chiba: (1) Shade: Set up a scaffold with a height of 2.5m to 3m, and maintain the illumination at 1000Lux to 2000Lux. (2) Excavation in the field: the bacteria are discharged on the raft, and the bacteria bag is removed after 5 to 10 days of ventilation, and then discharged on the raft. The spacing of the bacteria is 5cm to 10cm, the row spacing is 20cm to 25cm, and the soil is filled between the bacteria segments. The cover bacteria are not exposed, and the thickness of the cover soil is 1cm to 2cm. (3) Microclimate control in the shed: When the buds are formed until the fruit body is opened, the relative humidity of the air is maintained at 90% to 95%; when the opening is basically completed, and the edge of the cap is slightly yellow, the relative humidity of the air is maintained at 85%. 95%; the fruiting body tends to mature to the spore ejection period, the relative humidity of the air is maintained at 80% to 85%; the temperature of the control shed is 20 ° C to 30 ° C; the illuminance is maintained at 1000 Lux to 2000 Lux; the primordium of Ganoderma lucidum is formed to During the growth period of the baby, keep the ventilation so that the concentration of CO2 in the air is less than 0.1%. (4) Shuzhi: Keep 1 to 2 ganoderma lucidum per segment. (5) Overwinter: After harvesting, the winter season will be cleared, the film and shading net will be removed, and the exposed section will be covered with soil, with a thickness of 2cm to 5cm, and a deep drainage ditch will be dug around the shade. (4) Harvesting and processing. Harvesting time is from August to October. After the spores are mature, choose a sunny day to harvest with a sleeve, place the collected spore powder in a clean container, and dry or dry. Ganoderma lucidum spore powder was broken by physical method, and the wall breaking rate was over 95% at 25 ° C for 45 minutes. (5) Quality characteristics. 1. Sensory characteristics: (1) Ganoderma lucidum spore powder (unbroken wall): powdery, brownish yellow or brown, odorless, under high magnification microscope, the spores are nearly elliptical to oval. (2) Ganoderma lucidum spore powder (broken wall): powder (or fine grain), brown, odorless, under high magnification microscope, spores are fragmented. 2. Physical and chemical indicators: (1) Ganoderma lucidum spore powder (unbroken wall): water ≤ 10%, ash ≤ 2.0%, crude polysaccharide ≥ 2.0%. (2) Ganoderma lucidum spore powder (broken wall): moisture ≤ 9%, ash ≤ 2.0%, crude polysaccharide ≥ 2.0%, triterpene (based on oleanolic acid) ≥ 2.0 mg / kg, breaking rate ≥ 95%. 3. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
