Why Pleurotus ostreatus is not good
Some Pleurotus ostreatus growers write to say that their Pleurotus ostreatus is not growing well and want to know what the problem is. Here are some analyses and reminders on some problems that are often seen in cultivation:
The first reason may be that the ambient temperature and material temperature are not right. If the temperature range of mushroom production is higher or lower than that of the cultivated varieties, there will be no mushroom emergence or the phenomenon that the mushroom will no longer produce normally after a tide of mushroom turning to tide.
The second reason is the poor ventilation of the mushroom shed. Poor oxygen supply and high carbon dioxide concentration are not conducive to mushroom production. Serious hypoxia will cause a large number of mushroom buds to atrophy and suffocate.
The third reason is the improper method of spraying water. If you use too much water when spraying water, and spray directly on the culture material and young mushrooms, and close the doors and windows when spraying water, it will make the culture material stagnant and cause hyphae to suffocate to death. At the same time, the cover of young mushrooms is also due to water accumulation for a long time, a large amount of water absorption, it is easy to create conditions for the occurrence of a large number of bacterial diseases.
The last reason is the occurrence of diseases and insect pests. Due to improper selection and treatment of culture materials, mushroom houses, mushroom sheds and soil cover are not sterilized or not thoroughly sterilized, especially the old mushroom houses and sheds that have been used for many years are more prone to diseases and insect pests. After the pests invade, they will bite on the hyphae and fruiting bodies of Pleurotus ostreatus, causing them to break and lose water and die. The serious harm of diseases and insect pests will cause the mushroom body to atrophy, turn yellow, and finally rot and die after mushroom production. Therefore, you must carefully find the cause and take appropriate solutions.

Key points of High temperature Ash cultivation of New strain of Pleurotus ostreatus
In the spring of 2001, after the end of our Pleurotus ostreatus variety comparison test, when the temperature was as high as 34 ℃, several Pleurotus ostreatus fruiting bodies grew one after another on the waste heap covered by weeds, with gray-white to gray-black color, blossoming, and the largest flower weighed 2.4kg. After directional tissue separation and mushroom emergence test by means of bottle cultivation and bag cultivation, the performance was good. It was proved to be an excellent strain cultivated in summer after 2 years of pilot test. The virus-free treatment was carried out in the spring of 2004, and its character is more stable, so it can be used as the leader in the production of Pleurotus ostreatus in summer.

Diagnosis and treatment of mushroom degeneration
There were many bacterial regression phenomena in mushroom production in autumn and winter last year, and there were individual occurrences in spring and summer this year. The symptoms of bacterial degeneration were as follows: the germination of the bacterial mass was normal, the feed intake was slower than normal, the growth of the seed mass was radial, when the hypha length was 4~5 cm, the hypha gradually thinned from the seed mass, the tip hypha was dense, thick and white, and continued to develop, and the latter was diluted and sparse, and finally the whole surface of the bacterial bag was slightly gray or even no hypha. 40 days after sowing, the bacteria bag was gray, no normal white, see no
