Rare Edible Mushroom Cultivation Technique of Yellow Umbrella
The yellow umbrella (photiotaadiposa), also known as Fritillaria, willow mushroom, belongs to Basidiomycotina, Laminaria, Agaricaceae, Strophicaceae, and Parabium. The yellow-hulled fruiting body has a bright golden color and the stipe on the stipe is covered with yellow-brown scales. The mushroom is rich in protein, carbohydrates, vitamins and various mineral elements. The food is sticky, refreshing, delicious, and unique in flavor. The mushroom covered with a special kind of mucus, according to biochemical analysis shows that this substance is a nucleic acid, has an effect on the recovery of human energy, brain power. Yellow umbrella is a kind of medium and low temperature type edible fungus. It has simple production process, high output, and high selling price. It is one of the new varieties of edible fungi with promising future. 1. Cultivation season: The mycelial growth of yellow parasols ranges from 5°C to 35°C, and the optimum temperature is 23°C to 25°C. Mycelial growth beyond 28°C is inhibited. The temperature range of the fruiting body is 15°C-23°C, and the primordium formation is fast at 18°C-20°C. The pH value of 5.5-6.5 is most suitable. 2. Cultivation methods: The yellow umbrella mushroom is cultivated in the baghouse or in the wild. 3. Medium formulation: cottonseed hull culture medium: 70% cotton seed hull, 20% wheat husk, 8% corn flour, 1% gypsum powder, 1% sugar, 55 kg water, ph natural. Sawdust cottonseed husk medium: wood chips 35%, cottonseed husk 35%, wheat husk 20%, corn flour 8%, sugar 1%, gypsum powder 1%, water 55 kg. 4, bag making process: cultivation bag is 15-17 cm, polypropylene plastic bag, mixing materials, uniform water content of 58% bagging about 11 cm, the plastic bag tied, normal pressure sterilization should be maintained at 100 °C, 24 - 30 hours. 5, fruiting management: After the bacteria, the indoor temperature maintained 23 °C -25 °C, 10-13 days turning a heap. Generally after 50-60 days of culture mycelium full of material, unpack the bag to increase the relative humidity of the indoor air, heat and moisturize the material surface to form a layer of aerial hyphae, which is conducive to the formation of the primordium, combined with ventilation, scattered light, and the use of temperature difference. Stimulation, the greater the temperature difference, the more the primordium is formed. The water should be sprayed once a day. After forming a yellow rice grain in the primordium, appropriate ventilation is needed to keep the room temperature at 18°C-20°C and the humidity is 85%-90%. After 2 days, the primordium soon produces a yellow coat covering 1-3 cm long. The brown fruit fleshy fruit-body, in another 3-5 days, the finger-like fruit body becomes longer and thicker, and it differentiates into a stipe and a capsularis cap. The stipe no longer elongates in the next few days. Caps grow rapidly, 9-11 days after the formation of the primordium, and harvest when the vegetative screen is about to break down. 6, post-harvest management: after the first tide harvest, should eliminate the residual material on the material table mushrooms and withered mushrooms to rejuvenate the mycelium, accumulated nutrients 3-5 days later, and then pull the temperature difference to stimulate mushrooming, repeat the above management.
