How to grow Pleurotus ostreatus with straw to produce high yield?

How to grow Pleurotus ostreatus with straw to produce high yield? Solve the problem of using straw to grow Pleurotus ostreatus, want to get high yield! You can refer to the following methods for planting. First, the selection and disinfection of straw: straw is the substrate for the growth of Pleurotus ostreatus. The nutrition of Pleurotus ostreatus growth mainly comes from cellulose, hemicellulose and lignin in rice straw. The quality of disinfection is not only related to the physical and chemical properties of the matrix, but also to the contamination rate of miscellaneous bacteria. Therefore, the selection and disinfection of rice straw are the prerequisites for high and stable yield. The straw with good texture is golden, striped, resilient and nutritious. This requires that in the rice harvest season, millet should spread out the straw immediately after threshing, and collect it for use in time after drying. The yield of Pleurotus ostreatus is lower when the straw is drenched in the rain and then dried in the sun. Because these rice straws have often been infected by miscellaneous bacteria or caused by high-temperature fermentation and nutrition loss caused by stuffing for too long, affecting the yield of Pleurotus ostreatus. For the disinfection of rice straw, the concentration of lime water (lime for quicklime) should be controlled at 5%. Excessive concentration will change the PH value of the matrix and hinder the growth of Pleurotus ostreatus. If the concentration is too low and can not achieve the purpose of disinfection, the yield will be reduced directly or indirectly. 2. Strictly control the suitable temperature: the mycelium of Pleurotus ostreatus can grow at 15 ℃ and 35 ℃, and the optimum temperature range is 24 ℃. The hyphae above 30 ℃ were easy to aging and the yield was not high. Under 20 ℃, the mycelium grew slowly and the cultivation period was prolonged. It is also possible to be invaded by miscellaneous bacteria, resulting in a reduction in production. On the other hand, the lower temperature should be controlled for the formation of fruiting body. Although the hyphae can kink to form fruiting bodies between 8 ℃ and 25 ℃, the most suitable one is 15 ℃. At this time, the fruiting body grows well, the mushroom shape is stout, and the fruit body is of high quality and high yield. Therefore, the mushroom room must hang a thermometer, easy to observe, correctly grasp the appropriate temperature, so that Pleurotus ostreatus has a good ecological environment, is the guarantee of high yield. Third, Pleurotus ostreatus inoculation and auxiliary materials: the inoculation should be layered sowing (generally divided into three layers of auxiliary materials, three layers of sowing), the surface of the material surface must be sowed, and the sowing amount is slightly larger. In this way, the bacteria are evenly distributed in the material, which is easy to expand around and lay the foundation for early mushroom production. Because the straw is cut around a section of 20cm, and the paving material is taken to disrupt the paving method. Therefore, the forage just laid on the mushroom bed is relatively loose and the gap is large, which affects the spread of hyphae. Therefore, after laying the material and sowing, the material surface was pressurized by plank for 5 days to make the bacteria come into close contact with rice straw to facilitate the spread of bacteria and hyphae. The surface seeding rate is large, so that the bacterial line can quickly cover the whole material surface, reduce the chance of miscellaneous bacteria pollution, and thus increase the yield accordingly.
