Bionic black fungus cultivation technology
First, the cultivation season and preparation of materials 1, cultivation time: the choice of cultivation time is the key to the success of black fungus cultivation, and the level of production is closely related to the quality of poor, the bag should be selected from early October to November, the mountains can be appropriate early, This time is ideal, when the room temperature at 28-15 °C, air humidity of about 65%, and the temperature is gradually lower, bacteria activity at a low ebb, is conducive to black fungus mycelium colonization and eating, but also conducive to ear in early spring. 2, the ratio of raw materials: black fungus is wood rot fungi, with wood chips as a culture material, its nutritional composition can meet the needs of growth and development of black fungus. Suitable tree species for cultivation of mushrooms and fungus are suitable for growing black fungus bags. Pine, fir, cypress, etc. because of containing oils, alcohols, ethers and other substances, Aceraceae and stability of the tree species also contain aromatic substances, these tree species must be processed to cultivate black fungus, otherwise should not be used. Sawdust is smashed into a grain shape with a sieve of 8 mm. Cottonseed hulls and rice husk flour are also ideal for cultivation. Bran, rice bran and other accessories compose the medium. Raw materials are fresh and mildew-free. The formula is as follows: (1) 80% of wood chips; 18% of bran; 1% of gypsum powder; 1% of caramel; (2) 68% of miscellaneous wood chips; rice hull powder 15%; bran 16%; lime 0.5%; sugar 0.5%; (3) Mixed wood chips 65%; cottonseed husks 24%; bran 15.5%; lime 0.5%; Second, the production process Bags of black fungus mix when the water content of bag mushrooms slightly dry, with 50% -55% is appropriate. Due to the slimness of the black fungus mycelium and the slower development of the fungus, the culture material is slightly dry, the gap is large, and the oxygen content is relatively sufficient, which can significantly accelerate the mycelium of the fungus, and is favorable to the later period (field management). Bagging, sterilization and bag mushrooms (1515 tube material) similar. Inoculation application inoculation box under sterile conditions, each bag to connect four points, appropriately increase the inoculum size, access with a whole strain of bacteria, so that the black fungus mycelium rapid growth and occupation of the inoculation mouth. After inoculation, the mouth was tied with a bag and transferred to the culturing room. The culturing room should be cleaned in advance, sterilized with sulphur or sprayed with 5% phenol or peracetic acid on the walls, space and ground. After the odor of the medicine is distributed, the inoculated bag of bacteria is piled into a parallel pile or "well" shape. The optimum culture temperature has great influence on the growth of mycelium of black fungus. In order to make the mycelia of black fungus grow normally, the room temperature must be differentiated according to different growth periods. Mycelium growth stage is divided into: Germination period: 15 days after inoculation, the first 10 days of indoor temperature is appropriate to 26-28 °C, so that the hyphae in the most suitable environment to accelerate the eating, planting and spreading, occupation of culture materials, Become an advantage, reduce bacterial contamination, but should not exceed 30 °C, 10 days later with the growth of hyphae, the bag temperature gradually increased, the general bag temperature will be higher than the chamber temperature 2-3 °C, so adjust the room temperature at 22 - 24°C. Robust period: After 20 days, mycelia breaks down and absorbs the strongest nutrients. The mycelium is prosperous and vigorous, the metabolism is accelerated, and the temperature of the bag continues to rise. The room temperature is appropriate at about 22°C. At this time, because of special attention to scattered heaps to prevent abnormal temperatures, ventilation should be increased. Mature period: that is, after 40 days, the mycelium enters the physiological mature stage, which is about to transition from vegetative growth to reproductive growth. The temperature of the bag is gradually reduced and maintained at about 20°C. Observing the temperature change, the cultivation households mainly rely on the door and window switch. When the door is warmed up, it must pay attention to the temperature and timely ventilation. Although the temperature drops, the temperature can still rise after the door is closed. Therefore, the bacteria should be paid attention to in time to avoid heaping up the bacteria. When the mycelium is full of bags, it can be moved to the cultivation field for ear management. Third, the ear field selection of well-ventilated, sunny, convenient water source, no source of pollution, flood control fields or lawn as the ear. Integral turtle trampoline, 120cm wide, unlimited length, side ditch for the sidewalk. With a small wooden pole or wire frame, slightly thinner than the mushroom tube. The trampoline is covered with hay to moisturize (or cover it with a mulch) to prevent the erosion of the earphones by the sediment, so that the earpieces are clean and free of impurities and pollution. The quality after drying is excellent, the earpieces do not need to cover the film, and the shade is not built. Shed, open-air stadium, making it smooth. IV. Tube Discharge and Ear Management In early February, a good ear tube will be transferred to the ear field. Choose a sunny or cloudy day. Put the ear tube into 180 ear holes (using a 0.5 mm thick nail head system). Made of boring tools), using no bag, a week after the ear hole, see the ear hole hyphae recovery before spraying water management, spray sooner or later, every half an hour, depending on the growth of their fruiting bodies plus Large amount of water can be sprayed when the temperature is low, high temperature (daytime) does not spray, and windy days (morning and evening) are sprayed more frequently. Water management is the key to the process of black fungus cultivation. When the primordium is formed, The relative humidity of the cultivation field should be 90%-95%. Dry, wet and dry, alternating environment, when the temperature is high, should be sprayed early and late, when the air is dry, increase the number of water spray. Water spray stopped 1 day before harvest. After harvesting, keep the bacteria for 7 days, and spray the water for 8 days to moisten the culture. After the new ear buds are formed, continue spraying. Eighty-nine mature ears can be picked, pick two batches of fungus, fungus tube for the first time, so that both ears evenly. Promote mycelium formation fruiting bodies, a total of 4 to 5 batches of picking, black fungus processing dry is relatively simple, drying in the sun can be, storage is also very simple, into the film bag or woven bag stacked in a dry dark place. V. Attention to problems The main problem existing in black fungus sawdust bags is mold contamination. This is because the earpiece lacks a protective layer like the bark of the segmental wood, like the fungus layer of the mushroom stem tube, so it will cause the infection of the bacteria. In addition, the black fungus mycelia is slim, lacks the robustness and resilience of shiitake mushroom hyphae, and because the black fungus is a glial mushroom, in the ear bud and ear stage, if the temperature and humidity are poorly managed and ventilation is poor, it is easy to attract Pests and diseases. Therefore, we adopt an open-grown cultivation method that does not build shade and do not cover with thin film. It is an effective measure to solve the problems of ventilation and dehumidification, and it can also avoid breeding opportunities for germs and insect pests. Appropriate ear arrangement time; In the early spring temperature, humidity, air and other superior conditions are biased toward the growth of black fungus, so that the ear cannula high-yield, high quality has been guaranteed, so that black fungus made material breakthroughs in the development of breakthroughs, yield stability; Scientific methods pierced the ear canal so that the tube is not damaged by stimulation, and the ears are even and neat, and the fungus is picked up without impurities. In the early spring, the water is evenly mixed, the ear is early, the tide is fast, there are no pests and no pesticides are sprayed, and the management is simple and easy. The quality of fungus is good, the color is deep and fleshy, and the flower shape is comparable to that of wood fungus, 80% of which reaches the export standard.
