Perforated aeration is not difficult to cultivate Pleurotus ostreatus in summer
Due to the high temperature in summer, the three-dimensional cultivation of Pleurotus ostreatus in plastic bags will often cause serious pollution and even cause cultivation failure. Whether it can break through the germ barrier is the key to the cultivation of Pleurotus ostreatus in summer, and it is also the most worrying problem for mushroom farmers. Practice has proved that drilling ventilation and increasing oxygen is an effective method to solve the problem of cultivating Pleurotus ostreatus in summer.
1. Punching time
It is usually carried out 3-5 days after sowing, when the hyphae become white and germinate and begin to extend to the culture material. If the hole is punched too early, the hyphae have not germinated, and it is easy to pollute the miscellaneous bacteria; if the hole is too late, the hyphae will lack oxygen during the development period, which will affect the growth and development of the hyphae.
Second, the punching position
The drilling site should be strictly controlled on the strain layer or the extension of the hyphae. Especially when the amount of bacteria is small and the mycelium extends slowly, you can't punch holes everywhere in the bacteria bag, so as not to cause miscellaneous bacteria pollution and insect pests.
Third, the size and number of holes
You can use a pin when drilling (tie 3-4 pins to the chopsticks). The number of holes was 10-12 per bag around the bacterial layer, and then with the development and extension of the hyphae, the holes were punched once every 5-7 days and 3 times in the whole bacterial period.
Fourth, the advantages of the method of drilling ventilation and increasing oxygen.
1. Promote the fungus to produce mushrooms quickly and shorten the cultivation cycle. two。 Prevent the pollution of miscellaneous bacteria, improve the success rate of cultivating Pleurotus ostreatus in summer, and greatly reduce the investment risk. 3. The realization of annual production of Pleurotus ostreatus makes up for the shortage of fresh products of Pleurotus ostreatus in summer, thus greatly improving the economic benefits of mushroom farmers.

How to cultivate Pleurotus ostreatus in greenhouse
Pleurotus ostreatus has the advantages of fast growth, strong stress resistance, a wide range of culture materials, convenient cultivation and management, and can be cultivated in four seasons. The cultivation of Pleurotus ostreatus is mainly in greenhouse in our province. The author has sorted out the cultivation techniques of Pleurotus ostreatus in greenhouse, which can be used as a reference for farmers. The main results are as follows: 1. varieties should be used in early spring, medium and high temperature varieties in late spring and early summer, and high temperature varieties in summer and autumn. 2. the middle temperature type varieties in the production season produce the original seeds from November to December and from January to February; the high temperature type varieties

High-yield techniques of Pleurotus ostreatus cultivated in coarse sawdust fermentation material bag
At present, with the development of edible mushroom industry, the demand for raw materials is increasing. The price of fine sawdust in three northeastern provinces has soared in recent years, but coarse sawdust has become waste (such as coarse sawdust leaked from electric sieves on chippers and coarse sawdust crushed by branch shredders). The author uses the local rich coarse sawdust as the main material for fermentation to cultivate Pleurotus ostreatus, which is summarized as follows: 1 the tested strain Pleurotus ostreatus 2026 was introduced from Shijiazhuang High-tech Edible Mushroom Station in Hebei Province to provide mother species. The original seed is corn kernel medium, 99% corn kernels and 1% gypsum. Put the corn kernels
