3. Research contents of1:
3. The Pleurotus eryngii and Hericium erinaceus carried by the 20th recoverable scientific technology and experimental satellite were screened at 1 and 1, and their morphological, cytological, physiological, molecular biological and agronomic characters were tested. From the end of 2005 to the beginning of 2006, strains with excellent characters were cultivated, and excellent new varieties suitable for production were screened out, making their products easy to transport and store.
3. 1 2 plans to expand the production area of new varieties in two years, with the production area of15000m2 in 2006 and100000m2 in 2007.
3, 2 key technologies:
3. 2 1 strain is carried in space to ensure the survival of Pleurotus eryngii strain in space.
3.2.2. Screening of microbial strains to ensure that beneficial variations and varieties with excellent characteristics of Pleurotus eryngii can be screened out from numerous Pleurotus eryngii strains.
Detect 3, 2 and 3 characters.
3, 2 and 4, molecular biological tests were carried out to detect gene changes.
3, 3 process route:
Strain loading → strain rejuvenation → strain screening (morphological, cytological, physiological and agronomic characters) → molecular biological detection → new variety identification → patent application → industrial development.
3, 4 research arrangements:
The research process is divided into three steps: the first step is to carry Pleurotus eryngii and other strains into space in September 2004. The second step was to screen Pleurotus eryngii strains in the Institute of Microbiology, China Academy of Sciences in September 2005. Thirdly, the selected Pleurotus eryngii strains were tested for strain production and their agronomic characters were observed. At the same time, the selected excellent strains were detected by molecular biology to identify new varieties.
4. Market demand analysis
The space mutation breeding of Pleurotus eryngii and the breeding of excellent new strains will expand the cultivation area of rare Pleurotus eryngii and increase the benefits. Edible fungi industry has become the first choice for agricultural industrial structure adjustment with low input and high output, and the input-output ratio can reach 1: 1-2. The price of high-grade rare mushrooms is on the rise.
4. 1 There is a great demand for rare edible fungi in the international market:
China's edible fungi products sell well in the United States, Japan, South Korea, Germany, France, Hong Kong and Macao, and there is a great demand. Developed countries regard edible fungi as pure natural and pollution-free health food, which is their main food source and needs to be imported in large quantities every year. Some foreign pharmaceutical companies import a large number of edible fungi at all costs every year, and some edible fungi have been refined into precious medicines and health foods. Acupuncture drugs such as "polysaccharide" of Lentinus edodes and "polysaccharide" of Ganoderma lucidum are good anticancer drugs, and their value is quite expensive. Tianma pills, tablets, Hericium erinaceus slices, Ganoderma lucidum paste, Ganoderma lucidum tea, etc. They all have high therapeutic and health care functions. Edible fungi products enjoy a high reputation in the international market, and the market prospect is broader. Edible Pleurotus eryngii is a rare edible fungus, which can improve gastrointestinal function and has obvious cosmetic effect. Drugs have the function of lowering blood pressure and blood lipid, and are favored by consumers at home and abroad.
4.2 The domestic market has huge consumption potential:
China has long had the habit of eating edible fungi, especially edible black fungus, mushrooms, shiitake mushrooms and ganoderma lucidum. In recent years, new varieties such as Pleurotus eryngii, Pleurotus nebrodensis and Boletus have been introduced, which are more popular among people.
At present, the annual output of edible fungi in China is 7.8 million tons, accounting for more than 65% of the world's total output, with a total output value of 365.438+0.4 billion yuan and foreign exchange earning of 600 million US dollars. China has become a big exporter and producer of edible fungi, in which Agaricus bisporus accounts for more than 20% of the world total, and Lentinus edodes accounts for more than 70% of the world total. The output of Lentinus edodes, Pleurotus ostreatus, Auricularia auricula, Poria cocos, Tremella fuciformis, Hericium erinaceus and Volvariella volvacea in China ranks first in the world. In recent years, the development of some rare mushrooms, such as Pleurotus eryngii and Pleurotus nebrodensis, has made full use of corn cob, wheat straw, straw and other crop wastes, turning waste into treasure, and there is great room for development.
4, 3 space mutation breeding of Pleurotus eryngii:
The space mutation breeding of Pleurotus eryngii will enrich the variety resources of Pleurotus eryngii in China, and the series of excellent Pleurotus eryngii varieties can meet the market demand for new Pleurotus eryngii varieties to some extent.
