So how to use Chinese herbal medicine residue to grow straw mushrooms? It turns out that the residues of Chinese herbal medicine must be processed before they can be used to grow straw mushrooms. There are two processing methods: one is to put the fresh unfermented Chinese herbal medicine residues out of the pot into a bag, soak them in water for about half a day, then take them out and pile them into a pile, about 2 meters wide and 1.5 meters high, and cover them with a film to keep them moisturized. , ferment for about seven days, and the pile needs to be turned once during this period. The other is to directly add lime water to the residues of Chinese medicinal materials that have been piled up for a few days or longer, and then ferment them for 3-5 days, turning them once during the period. Fermentation residues of Chinese medicinal materials can replace rice straw and bagasse as raw materials for straw mushroom cultivation.
Coprinus comatus and straw mushroom are both grass-rot fungi. Their hyphae can secrete and produce a variety of isoenzymes, which can effectively decompose and absorb cellulose, hemicellulose, lignin, etc. , can directly utilize starch, glucose, sucrose, etc. , but not lactose. After the active ingredients of Chinese medicinal materials are extracted, they are rich in cellulose, hemicellulose and lignin, and contain a certain amount of starch, amino acids, inorganic salts, etc. , supplemented by cottonseed hulls, bran, corn flour, straw, wheat straw, etc. , can provide sufficient nutrients and carbon and nitrogen sources for the growth of coprinus and straw mushrooms. Temperature: Coprinus comatus is a medium-high temperature fungus. The mycelial growth temperature is 5℃~35℃, and the suitable temperature is 20℃~28℃; the fruiting body development temperature is 18℃~22℃, and the suitable temperature is 15℃~22℃. Straw mushroom is a high-temperature fungus. The suitable temperature for mycelium is 28℃~35℃; the suitable temperature for the growth and development of fruiting bodies is 30℃~35℃.
Humidity: The humidity of Coprinus comatus mycelium growth medium is about 65%, and the relative air humidity is 65~70%. The humidity of the fruiting body growth medium is 65~70, and the relative air humidity is 85~90. The humidity of straw mushroom growth medium is 68~75, and the relative humidity of air is 70~75. The humidity of the fruiting body growth medium is 70~75, and the relative air humidity is 90~95. Coprinus comatus and straw mushrooms are aerobic fungi. When there is sufficient oxygen and the carbon dioxide concentration is 0.2~1.5, it is beneficial to the growth and development of mycelium. When the carbon dioxide concentration is greater than 3, it will inhibit the growth of mycelium. The growth and development of fruiting bodies requires a large amount of fresh air and is sensitive to carbon dioxide concentration. If it exceeds 0.2, it is detrimental to its growth. Straw mushrooms, also known as orchid mushrooms and brachiopod mushrooms, originated from Nanhua Temple in Shaoguan, Guangdong. Artificial cultivation began in China 300 years ago and was introduced to other countries by overseas Chinese in the 1930s. The straw mushroom is an important tropical and subtropical mushroom and the third largest cultivated edible fungus in the world. my country's straw mushroom production ranks first in the world, mainly distributed in South China.
The cultivation of straw mushrooms in the existing technology mainly uses cottonseed hulls and waste cotton as raw materials, and then uses straw and corn cobs as raw materials. However, as cottonseed shells have more and more functions and limited output, the production cost of straw mushroom culture is getting higher and higher. There is an urgent need to develop a raw material as the main raw material for straw mushroom culture. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, magnesium, calcium and other organic nutrients. It is a multi-functional renewable biological resource; however, only a small amount of crop straw is used in our country. Used as fertilizer and crop feed, most is burned. With the rapid development of agriculture, China's grain production is getting higher and higher, and there are more and more crop straws. The burning of crop straw will cause great harm to the atmosphere, increase respirable particulate matter in the air, and harm human health. The patent with publication number CN102173949B discloses a straw mushroom cultivation substrate, which contains traditional Chinese medicine dregs, straw and yield-increasing agent. The ratio of traditional Chinese medicine dregs to straw is 70-90 of traditional Chinese medicine dregs, 10-30 of rice straw, and yield-increasing agent. Add at a dosage of 5-10 kg/cubic meter.
