Pleurotus ostreatus sells well in domestic and foreign markets. In particular, supermarkets in new york, Los Angeles, Chicago and other metropolises in the United States are in short supply, and they have become hot items.
Component value:
The content of crude protein, crude fat, crude fiber, carbohydrate, total amino acids, E/E+N and E/N ratio of 1 and stropharia rugoso-annulata were 25.75%, 2. 19%, 7.99% and 68.23%, respectively. The contents of phosphorus and potassium in mineral elements are relatively high, which are 3.48% and 0.82% respectively.
2. The big dome is rich in bioactive substances such as protein, polysaccharide, mineral elements and vitamins, and the amino acid content is up to 17, which is complete in essential amino acids. The contents of total flavonoids, total saponins and phenols in bioactive substances are all above 0. 1%, and the contents of taurine and Vc are 8 1.5 and 53. 1mg/ 100g, respectively.
3. The inhibitory rate of Pleurotus ostreatus on S- 180 sarcoma and Ehrlich ascites carcinoma in mice was as high as 70%. The dried Pleurotus ostreatus contains ash 1 1.4%, carbohydrate 32.73%, protein 25.8 1% and lipid 2.60%. The content of phosphorus in inorganic elements is the most, and the dry product of 100g contains about phosphorus 1204.65mg, followed by calcium 98.34mg, iron 32.5 1mg, manganese 10.38mg, copper 8.63mg, arsenic 5.42mg and cobalt 0.33.
4. It is also rich in glucose, galactose, mannose, ribose and lactose. 72.45% of total nitrogen is protein nitrogen and 27.55% is non-protein nitrogen. 42.80% of protein is albumin and globulin. In addition, it also contains a variety of vitamins, such as 100g dry Pleurotus ostreatus contains nicotinic acid 5 1.38mg, riboflavin 3.88mg, thiamine 0.5 1mg, vitamin B60.42mg and vitamin B120.4/kloc. Pleurotus ostreatus contains choline, betaine, histamine, guanine, guanidine and ethanolamine, among which histamine, ethanolamine and choline are higher.
5. Pleurotus ostreatus can use the straw of crops as raw material, and the mycelium of Pleurotus ostreatus can grow normally and produce mushrooms with the culture material without any organic fertilizer. If nitrogen fertilizer, phosphorus fertilizer or potassium fertilizer were added to the straw, the mycelium growth of Pleurotus ostreatus would be very poor. The effect of cultivating Pleurotus ostreatus with sawdust, manure, leaves and hay is not ideal. There are a large number of materials needed for large-scale cultivation of Pleurotus ostreatus, so it should be collected in advance and stored for later use. Crop straw can be straw, wheat straw, barley straw, black wheat straw, flax straw, etc.
Extended data:
1, 1922 American first discovered and reported Pleurotus ostreatus. 1930 Wild Pleurotus ostreatus was also found in Germany, Japan and other places. 1969 was domesticated and cultivated artificially in East Germany at that time. In 1970s, it developed to Poland, Hungary, the former Soviet Union and other regions, and gradually became an artificially cultivated edible mushroom in many European and American countries. 1980, the Institute of Edible Fungi of Shanghai Academy of Agricultural Sciences sent personnel to Poland for investigation, introduced strains, and tried to plant them successfully, but it was not popularized.
2. Since 1990, Sanming Institute of Fungi in Fujian Province has made a research on the topic, and cultivated Pleurotus ostreatus in orange orchards and fields has achieved good benefits, and it has been gradually extended to both inside and outside the province. Since 2008, it has been planted in Hebei Province, and there are also experimental growers in Beijing.
3. The introduction and popularization in recent years show that Pleurotus ostreatus has a very broad development prospect. First of all, the cultivation technology is simple and extensive, and it can be cultivated directly with raw materials, which has strong anti-impurity ability and is easy to succeed. Secondly, the cultivation materials are abundant, which can grow on all kinds of straw culture materials (such as straw, wheat straw, flax straw, etc.).
4. In the vast rural areas of China, it can be used as a major measure to treat straw. The cultivated waste can be directly returned to the field to improve the soil and increase fertility. Thirdly, Pleurotus ostreatus has strong stress resistance and a wide temperature range, which can produce mushrooms at 4~30℃ and can naturally overwinter in Fujian, Guangdong and other provinces.
5, due to the long planting season, it is beneficial to adjust the listing of other mushrooms or vegetables in the off-season. Fourthly, because of its high yield, low production cost and rich nutrition, Pleurotus ostreatus, as a new product, is easily accepted by consumers.
