Cultivation techniques of Pleurotus ostreatus: how to match the cultivation raw materials of Pleurotus ostreatus?

How to match the cultivation raw materials of Pleurotus ostreatus? Please give guidance to Pleurotus ostreatus cultivation raw materials can refer to the following methods: the added nutrients should be based on organic nutrition, supplemented by inorganic nutrition, which is very helpful to enhance the stamina of Pleurotus ostreatus. Generally speaking, the organic nutrients are mainly composed of wheat bran, corn flour, rice bran, etc., and the general addition amount is 20-30%. The organic nutrition content is too large. One of the disadvantages is that the pollution rate is greatly increased, and the second is that it affects the air permeability of the culture materials. resulting in slow mycelium growth and delay the mushroom season. Inorganic nutrition is generally potassium dihydrogen phosphate, magnesium sulfate, etc., generally added 0.2% 0.5%, too much will affect the water absorption capacity of mycelium. It should be emphasized here that with the increase of the total yield of Pleurotus ostreatus, improving the nutritional content of the culture material is a very important aspect, and another aspect is to ensure that the culture material has a strong water absorption capacity. At present, the conventional cottonseed hull is generally short, but it is impossible to add a lot of water to the cottonseed shell with short cottonseed hull. If you use this raw material to cultivate Pleurotus ostreatus, during the period of mushroom emergence, the fruiting body will not get sufficient water supply. In this way, the commodity and growth specifications of the entity will be difficult to guarantee, let alone maintain a high yield. In this case, we can adjust the formula appropriately and add 30% to 50% of the raw materials with strong water absorption capacity, such as cotton soil wool, corncob, etc., which not only improves the water absorption of the culture material, but also saves the cost, which can be said to kill two birds with one stone. For the cultivation of Pleurotus ostreatus, the suitable water content of raw materials should be 60% 65%. Specifically, the ratio of material to water can be controlled at 1.15% 1.5% 1.6 before fermentation and about 1.3% before inoculation. Cotton velvet, as the garbage of the original cotton mill and cotton oil factory, has been well applied in recent years. The experimental base of Shouguang Edible Fungi Research Institute used the main material formula of half cotton skin and half soil wool to produce Pleurotus ostreatus in 2005, and achieved very good results. the highest bioconversion rate reached more than 80%, creating good economic benefits. Practice has proved that adding a certain amount of lime to the formula can promote the rapid growth of mycelium, and the amount of lime can be controlled at 2: 5%, so that the pH can be maintained at about 8: 9 after the completion of culture material fermentation. It is OK not to add lime, but the growth of mycelium will become slow, which will have a great impact on the reasonable arrangement of mushroom season.
