The technique of planting Ganoderma lucidum with wooden bags

At present, artificial cultivated Ganoderma lucidum in China can be divided into three types: (1) medicinal type: such as Taishan Ganoderma lucidum, South Korea Ganoderma lucidum, Yuanzhi No. 6, etc. (2) Medicinal and ornamental type: such as black ganoderma g43-1, black ganoderma g43-2, etc. (3) Ornamental type: such as Ganoderma lucidum, wrinkled cover, Ganoderma lucidum, etc. Due to the different consumer markets in different places, growers are guided by the local market and flexibly select marketable Ganoderma lucidum varieties to produce the best economic benefits.

2. The formula of culture medium (1) 73% sawdust, 25% wheat bran, 1% soybean powder, 1% gypsum powder and proper amount of water. (2) Cottonseed hull 98%, sucrose 1%, gypsum powder 1%, water appropriate. The above formula (I) or (II) is mixed with water and used as filler for later use. At 65%, take 8-10 pieces into a bundle, and use a knife to flatten the peripheral burrs for use. Because Ganoderma lucidum has strong ability to decompose lignin, wood blocks can not only preserve the density of logs, but also have many gaps and good ventilation performance after bundling. Third, bagging and sterilization Take a polyethylene special bacteria bag with a width of 24 cm and a length of 48 cm. At the bottom of the bag, put a few handfuls of sawdust or cotton shell culture medium at the bottom, carefully put wood blocks into the bag, fill the gaps with culture medium and cover them with wood blocks. After closing and tightening, put it into an atmospheric pressure sterilizer to cook at 100℃ for 10-12 hours or keep it under 1.5 kg pressure in an autoclave for 3 hours to ensure complete sterilization. IV. Inoculation and strain management When the bag temperature drops to 28℃, put it into the inoculation box or room together with the strains and inoculation tools, and insert Ganoderma lucidum strains according to the aseptic operation procedures. The inoculated bacteria bags should be moved to a ventilated and dry place for shading culture. Because Ganoderma lucidum is an aerobic fungus, in addition to regularly turning the pile every 7-10 days during the culture stage, it is also necessary to combine the puncture hole or untie the bacteria bag mouth for ventilation. After 35-40 days of culture, hyphae can grow full of bags and reach physiological maturity. 5. De-bag and covering soil When the outside temperature is stable at 24℃, the mature bacteria bag can be moved into the 50% transparency of the Zhishi shed. First, remove the bacteria bag and carefully remove the bacteria column. Arrange it upright on the sesame bed according to the specification of 8×15 cm. Then take out vegetable soil or washed soil to fill the gaps between the tubes and cover the tubes by 1-2 cm. At last, the film on the arch is kept at bed temperature of 20℃, and the original base can be formed in about one week. 6. Management and harvest The quality of Ganoderma lucidum products mainly depends on field management. When the primordium grows to the size of a table tennis ball, the primordium is covered with a plastic ring with a diameter of 3 cm, forcing the handle not to open and forming a handle and a cover. When the fungus cover increases to 2-3 growth circles, in addition to keeping the fungus bed moist, it is necessary to combine loosening and topdressing decomposed manure. When the fungus cover increases to 8-10 growth circles, the transmittance of the fungus shed should decrease from 50% to 20%. Ganoderma lucidum will become black and oily in low light environment, and the cap will obviously thicken. After 45 days of growth and ejection of a large number of brown spore powder, Ganoderma lucidum can be cut off with branch scissors, graded, dried and sold. According to the current market price of black ganoderma lucidum, the net income per mu can reach tens of thousands of yuan.
