Large-scale cultivation of Ganoderma lucidum in Micro-spraying Project

(1) The best shade net is black shade net with shade ratio of 85%. Net shed type, according to the construction form: flat roof type, net shed is flat, shed height 2.5 meters; half slope type, net shed is "herringbone" shape, net lining 6 meters wide film; full arch type, net shed is semicircular, net lining 6 meters wide film, shaped like a small tunnel. Press fixed material cent: bamboo supports net shed, barbed wire net shed and plastic nylon line net shed 3 kinds.

(2) The micro-spray project must be combined with the supporting micro-spray engineering new technology to provide a good ecological environment for the growth of Ganoderma lucidum. Microspray material is bidirectional microspray nozzle. On the hard plastic water pipe with a diameter of 10 mm, install a micro-nozzle every 1.2~1.5 meters (to be installed at the same level, the water pipe at the same level should be straightened, do not undulate and twist), so that the water mist can be sprayed to the edge of the ridge. When the water pressure at the end of the water pipe reaches 1.92X105~2.94X105, the droplet diameter is 0.2~ 0.4mm, the spraying uniformity is high, and the relative humidity of the air can quickly reach more than 90%. During installation, micro-jet pipeline can be installed according to natural water level difference (more than 8 meters), or micro-jet can be carried out by pumping water with pump or submersible pump. (3) The fungus bags for short basswood clinker cultivation can be made in all seasons except July and August when the temperature is higher. In Fujian, it is best from mid-November to late December or mid-February to late March. 2~3 batches of fruit bodies can be harvested in the same year or the following year. Among the trees suitable for cultivating Ganoderma lucidum, Castanopsis fargesii, Quercus acutissima and Quercus acutissima of Fagaceae are the most important. Oak, Castanopsis carlesii and so on are most suitable. Liquidambar, Casuarina equisetifolia, Sapium sebiferum, Elm, Poplar, etc. are also very suitable. Cut the logs into short sections of 12~15 cm and pack them in plastic bags 85 cm long and 65~75 cm wide. Tie the short logs into bundles with No. 14 iron wire or bamboo strips. The cross sections at both ends should be flat. Each plastic bag can hold two layers of bundled logs. Another method is to cut the log into 30 cm long, tighten one end of the plastic cylinder with a length of 55~60 cm and fold it back into a bag. The bottom of the bag shall be paved with a layer of culture medium prepared from sawdust 78%, bran 20%, sugar and gypsum 1% respectively. After putting it into the log, another layer of culture medium shall be paved and the bag mouth shall be fastened with thread. After bagging, sterilize in atmospheric sterilization oven and maintain at 100℃ for 12 hours. After sterilization, inoculate according to routine method. Ganoderma lucidum strains used in Songxi County are Xinzhou, Huizhou 6 and Huizhou 8 introduced from Japan. These strains are large, round, high yield and good quality. (4) Incubate in the germ chamber after inoculation, and keep the temperature at 25~30℃. Generally 7~15 days, hyphae that is, covered with the surface of the log, 50 days or so hyphae grow to the interior of the log, can be moved into the black shed bag buried soil. (5) After the fungus wood is buried in the soil, manage the unbagged fungus wood, bury it vertically (or horizontally) in the prepared bed in the black shed, bury the fungus wood in the soil 2/3~3/4, the interval between the fungi is 8~10 cm, and then cover a layer of reed grass or dry straw 10 cm thick as a buffer layer, which can prevent the sediment from splashing on Ganoderma lucidum when spraying water, prevent weeds from growing and reduce soil moisture evaporation. In order to make Ganoderma lucidum flower big cover thick, should go inferior to stay strong, each fungus tree only stay 4~5. If the two Ganoderma are too close apart, bamboo and wood should be used to gently open the two stems and let them become Ganoderma.
