The history of artificial cultivation of black fungus in Luohe City dates back to the 1970s and has a history of nearly forty years. In the 1970s, Luohe City began to use wood segments for pure fungus cultivation of black fungus. In the late 1980s, the state issued the “Tianbao Project” and other forestry policies, ending the blackwood ear wood cultivation history in Heihehe City, due to Huangsongdian The black fungus cultivation in the town section is large, and the cultivated household first uses the black fungus species (bag) to carry out the ear test in the greenhouse or in the greenhouse and succeeds. The "Huangsongdian black fungus" is named.

(I) Product History The history of artificial cultivation of black fungus in Luohe City can be traced back to the 1970s, and it has been nearly forty years old. In the 1970s, Luohe City began to use wood segments for pure fungus cultivation of black fungus. In the late 1980s, the state issued the “Tianbao Project” and other forestry policies, ending the blackwood ear wood cultivation history in Heihehe City, due to Huangsongdian The black fungus cultivation in the town section is large, and the cultivated household first uses the black fungus species (bag) to carry out the ear test in the greenhouse or in the greenhouse and succeeds. The "Huangsongdian black fungus" is named. By the early 1990s (1994), the black fungus growers in Huangsongdian Town took the black fungus bags out of the room to the outside for earing, and used a "V" mouth and a "1" mouth. The outdoor sun-cultivation is carried out by cutting the ear and other methods, so that the yellow fungus of Huangsongdian has unique quality from color, cultivation success rate, yield and quality. In 2005, Huangsongdian black fungus used the ground ear bed to lay plastic film, small mouth out ear, try to slap the ear and other technical measures to improve the quality of black fungus. Because Huangshaodian black fungus is of good quality and its external sense is obviously different from the common black fungus on the market, it has become synonymous with high quality black fungus, which is very popular and loved by consumers in the market. (II) The reality of the product 1. The status quo of resources The city of Luohe was evacuated to the town by the end of 2006, and there were 18 townships (blocks). According to the actual conditions of Huangsongdian black fungus production conditions, raw material resources and climate resources, there are 13 townships suitable for planting Huangsongdian black fungus, with a cultivation scale of 400 million bags and an average annual output of 10,000 tons. 2. Planting Status In 2005, the production scale of Huangshaodian black fungus in Luohe City reached 310 million bags, with a yield of 6800 tons, an output value of 450 million yuan and a profit of more than 40 million yuan. In 2009, the city developed 400 million bags of black fungus, with an estimated output value of 600 million yuan and a profit of 320 million yuan. Through decades of development, Huangsuodian black fungus production has formed a relatively complete production technology system from variety selection, bacterial bag production, bacterium management, smear or smear, picking and drying, and processing. Huangsongdian Town has become the green black fungus production base and the national black fungus standard production base in Jilin Province. 3. Research Status (1) Institutional Setup In 1999, Huangsongdian Town of Luohe City established a cooperative relationship with Jilin Agricultural University. Huangsongdian Town of Luohe City was used as a teaching practice base and research base of Jilin Agricultural University. From 2004 to 2008, the Provincial Edible Fungus Spark Technology Experts' Courtyard and the National Edible Fungus Spark Technology Experts Demonstration Project settled in Huangsongdian Town, Luohe City. At present, Luohe City has spontaneously established 16 edible fungus research institutions and 13 township agricultural technical service centers. There are more than 110 edible fungi cultivation and management technicians, and the actual problems of production are solved for Huangsongdian black fungus farmers. (2) After 20 years of introduction and wild species domestication research, the black fungus species resources were selected to screen out the ear 1, the ear 3, the Tianxiang Shuangfeng 1, the black 29, the black 916, the JI AU1, and the JI. More than ten varieties of black fungus, such as AU2 and Harvest 2, are superior to other varieties in quality, stress resistance, anti-hybrid and disease resistance, and the quality meets the quality requirements of Huangsongdian black fungus. (3) Production Technology The People's Government of Luohe City has invited experts from Heilongjiang Provincial Applied Microbiology Institute, Jilin Agricultural University, Yanbian Agricultural College, Dalian Quanhe Fungus Industry, Jilin Spring Fungus Industry and other scientific research units and enterprises to conduct on-site technical training. According to the development status of Huangshaodian black fungus industry, strengthen cooperation with scientific research units such as Jilin Agricultural University and Jilin Spring Fungus Industry to provide technical support for the production of Huangsuodian black fungus. By formulating technical regulations for the production of black fungus in Huangsongdian, the varieties are selected, the ingredients are bagged, the atmospheric pressure sterilization, the sterile inoculation, the indoor bacteria, the outdoor ear, the fungus picking and the natural drying are regulated, thereby improving the yellow pine. The inner quality of the black fungus. 4. Processing Status The infrastructure construction of research, base, processing and market in Luohe City is basically perfect. There are 3 black fungus processing enterprises – Jilin Heizun Food Co., Ltd., Luohe Songshan Food Co., Ltd. and Luohe City. Edible Fungus Co., Ltd. Processing black fungus products include compressed black fungus blocks, bags of selected black fungus, black fungus health products, diet foods and frozen foods, and deep processing of black fungus 3900 t. 5, product development and utilization of Huangshaodian black fungus containing polysaccharides - acidic isoglucan production of "auricular polysaccharide nutrient solution" and "ecological fungus tablets", can reduce blood clots, ease coronary atherosclerosis, Prevents thrombosis and lowers blood cholesterol levels. 6. Awards In 2004, Huangsongdian Black Fungus was awarded the title of “Famous Brand Product” by the Chinese Society of Fungi. V.
