Cottonseed hulls: According to the inherent quality of raw materials, cottonseed hulls are the preferred raw materials, which is not only traditional raw materials, but also one of the most convenient and most effective raw materials. While the cottonseed husks are best for small shells and long velvets. There are two kinds of “fake†products nowadays. One is that Xinjiang's large shells or light shells are shattered again. Adding floor-to-face cotton or waste lint blends is the first time to take possession of the goods. Two kinds of cottonseed husks are mixed with sand, such as the Yellow River sand, in order to gain weight, which is adulterated. "Fake" is not difficult to distinguish. Random sampling can be used to identify.
For cottonseed husks, we must say one more thing. In recent years, China's cotton is mostly genetically modified. As a by-product of cottonseed hulls, it also wears “genetically modified†hats. In foreign markets, it will reject GM foods. Therefore, we Pleurotus ostreatus and other edible fungi that are grown in the shell of genetically modified cottonseeds will be rejected or investigated when exported.
Corncob: Due to tight supply of cottonseed husks in recent years and high prices, mushroom cultivation costs have been soaring. Some mushrooms have been actively searching for other raw materials, such as corncob raw materials. Since 2010, corncob raw materials have become new raw material resources. Used to cultivate oyster mushrooms. Then, how does the corn cob cultivate the yield of Pleurotus ostreatus? Practice has proved that if done properly, the cultivation effect will not be worse than cottonseed hulls. The main feature of corn cob raw materials is that it is difficult to absorb water. The feature similar to this is that the amount of water absorption is high—the yield of corn cob cultivation is relatively high. Under the premise that the corn cob raw material has less nutrients and the ratio of carbon to nitrogen is extremely unreasonable, The reason for high output is the large amount of water.
Bagasse: As a raw material, it is rarely used for cultivation of Pleurotus ostreatus, and it is a very strong raw material resource. Its typical features are soft mechanism, high shrinkage, and low yield. In addition, the raw material has high sugar content, high carbon and nitrogen content, high contamination rate during germination, and relatively high disease incidence during mushrooming. With its important characteristics, producers should pay close attention.
Soybean meal: The basic physical properties are similar to those of straw, wheat straw, and bagasse, but their chemical composition is quite different. Soybean straw contains 70% carbon, 6% nitrogen, and a carbon-nitrogen ratio of about 12. It is a raw material for straw. The highest raw material, therefore, generally can not be used alone to cultivate, in order to avoid the occurrence of bacterial skin tissue, but a waste of nutrients and delayed mushrooming. It is recommended that it be mixed with corn cobs or other straws before cultivation.
Other straws: such as rice straw, wheat straw, rice husks, peanut pods, cotton stalk powder, etc., can be used in various places according to resource conditions. As long as the scientific formula is formulated, the ideal production goal can be achieved.
Xylose residue: The typical characteristics of raw materials are high acidity, fine texture, easy to cause poor ventilation within the bag, in addition to high water holding capacity. The use of this kind of raw material is very wide, especially in the northern regions where there are many enterprises producing xylitol, which produce a large amount of waste residue, which was previously regarded as waste, air pollution, occupation and acidification and pollution of groundwater, in addition to the cultivation of oyster mushrooms in recent years, It was a pity that a large number of companies such as power plants were burned. Then, after the xylose residue is mixed with lime powder, it is best dried and then reused. For example, cultivation with wet material is difficult for the novice. The characteristics of furfural slag raw material are very similar to xylose residue.
