The strain of Pleurotus ostreatus should be selected correctly in autumn
The quality of strain is the key to the high yield of Pleurotus ostreatus. The high-quality secondary and tertiary strains of Pleurotus ostreatus should have the following characteristics: the hyphae are dense, white, uniform and stout, fluffy, wall-climbing, a small amount of coral-shaped buds appear on the surface of the culture medium, and the appropriate age is 20-25 days. The cross-section mycelium of the strain is obvious and has obvious mushroom flavor. If a large number of fruiting body primordia appear on the surface of the culture medium, it means that the strain has matured and should be used as soon as possible.
Before introduction, the temperature type of the strain must be known, and then the temperature type of the strain must be determined according to its own conditions and the temperature of mushroom production. When Pleurotus ostreatus was cultivated in August and September, due to the high temperature, the high temperature of more than 30 ℃ sometimes appeared in the mushroom emergence period, and the temperature decreased gradually after October. In order to ensure normal mushroom production during the period of high temperature and low temperature, the selected strain should be an excellent strain which can bear both high temperature and low temperature. The cultivation of Pleurotus ostreatus from mid-August to mid-September, Jiangdu 109and Huafeng 1, resident 9703 and P50 from late September to mid-October, and Heipingwang and 8801 from late October to late November. If the temperature type of the selected strain is inappropriate, it is not suitable for autumn cultivation, so we must be careful when introducing the strain. In addition, the strain should be selected according to the local natural resources. at present, the main raw materials for cultivating Pleurotus ostreatus are cottonseed shell and corncob. Different varieties have different ability to decompose the culture material, so it is necessary to choose the strain suitable for the culture material.

What are the key points of the management of Pleurotus ostreatus planted in autumn?
When Pleurotus ostreatus is planted in autumn, the temperature changes from high to low, the climate is humid and rainy, the miscellaneous bacteria are more active and dense, and the mycelium growth stage is not easy to manage. Therefore, in order to ensure success, the following technical measures can be taken: (1) thorough sterilization: the main cultivation methods are clinker cultivation and stacking fermentation material cultivation. Cultivation with plastic bags is easy to check and manage, and the success rate and bioconversion rate are very high. (2) select good varieties: the temperature decreases gradually in autumn, do not select high and medium temperature varieties, in case it is difficult to manage or deformed mushrooms due to low temperature in the later stage. The wide temperature type should be selected.

Production of Coprinus comatus with high quality by using waste of Pleurotus ostreatus skillfully
Coprinus because of its shape chicken named, its tender meat, delicious, nutritious. Coprinus comatus can be produced by using the leftovers of Pleurotus ostreatus and idle vegetable greenhouses. The dry material can be put into the 60m2 mushroom shed, and the coprinus comatus can be produced 750-1000kg. The market price is more than 4000 yuan. The economic benefit is considerable. Specific cultivation measures are as follows: 1. Prepare culture materials. Crushing the waste of oyster mushroom, mixing it with mushroom chaff 50%, cottonseed hull 37%, lime 6%, corn flour 7%, carbendazim 0.1%(extra).
