Grifola frondosa is an attractive anti-cancer drug source. On the one hand, the higher selenium content has the effect of resisting cancer, especially Griflan, with β-glucan as the glucan. Lord, which has the strongest anticancer activity, has a large proportion of 6-branched β-(1,3)-glucans, and is said to be more numerous than the shiitake mushrooms (Lentinan, PSK, Japan) and clouds that are already on the market. Zhizhi polysaccharide (Shanghai PSP) has a stronger anti-cancer ability; at the same time it is an excellent immunomodulator. As a traditional Chinese medicine, ashtree flowers and porcine fleas are equivalent, and can be used to treat urine, edema, beriberi, cirrhosis, ascites and diabetes, and are very valuable medicinal fungi.
Chestnut is a kind of wood rot fungi, which can be used for large-scale and commercial production of raw materials such as shoots, cotton hulls, rice straw, wheat straw, and bagasse.
Formulas for culture materials: (1) 78% rice straw, 10% wheat bran, 5% rice bran, 5% corn flour, 1% sugar and gypsum. (2) 80% wheat straw, 8% wheat bran, 10% corn flour, 1% for grain and gypsum. Fertilizer soil was added to both formulas by 20% and sprayed into the soil with 15 ml of En fertilizer (a special fertilizer) with a moisture content of 60% to 65% and a pH of 5.5 to 6.5.
Cultivation methods: The straw and wheat straw are cut into small pieces of 3-5 cm long, and the mixture is repeatedly pre-wet and mixed with lime water with a pH value of 7, so that the materials absorb water evenly, and then the other ingredients in the formula are mixed with the loam soil and the forage material. , so that the water content reaches 60% -65% (with hand-grip material, water stains without dropping), and then mix the material into a long heap fermentation 3-5 days, the middle turn 1-2 times, After the grass stems have been softened, they are put into a 17 cm 33 cm 0.05 cm polypropylene plastic bag. Each bag is filled with 250 g of dry material. At normal pressure, it is sterilized at 100°C for 8 hours, and then cooked overnight. After cold to room temperature, according to the full open sterile operation, inoculation, culture, generally about 30 days mycelium can be filled with bags. If the temperature, humidity, light and other environmental factors are appropriate, about 10 days can be found in the original base, this time you can take the bag out of the mushroom, and increase the relative humidity of the culture room up to 90%, can also be used bags and soil covering cultivation management. After the formation of the fruiting body primordium to the harvest period, spray water 1-2 times per day according to the specific conditions of the mushroom house and the site, combined with ventilation and ventilation. The mushroom body is picked when it grows to eight. The biological efficiency is generally up to 45%-60%, and every 100 grams of raw materials can be cultivated to earn 200-800 yuan.
Artificially cultivated chestnut mushrooms
Chestnut Mushroom is also known as Grifola frondosa. It is a food-and-drug combination mushroom and belongs to the genus Basidiomycetes. Chestnut mushrooms have a pine-like aroma, tender and tender, taste like chicken, crisp like magnolia. Chestnut mushroom was originally confined to the wild and its yield was very low. After being artificially domesticated by the Institute of Edible Fungi, Qianxi County, the yield was greatly increased. According to the analysis of the Quality Inspection Center of the Ministry of Agriculture, the artificially cultivated ash tree flowers in Qianxi County, Hebei Province, have superior nutrition and taste to shiitake mushrooms, which can be cooked into a variety of delicacies and are extremely precious and high-grade edible oysters. bacteria.
