High temperature No. 9 Pleurotus ostreatus
High temperature No. 9 Pleurotus ostreatus. Characteristics of ⑴: high temperature species, superimposed, gray cap, dark gray when the temperature is below 20 ℃, stipe, white pleat, compact and compact, high commercial quality. Without infection of yellow mushroom disease and brown rot, the biological efficiency of Pleurotus ostreatus is about 150%. The suitable temperature of ⑵ was 6-38 ℃ and 12-36 ℃ respectively.

Mite control measures of Pleurotus ostreatus in high temperature season
1. The distribution and damage of acaroid mites: this mite is a worldwide widespread species. In the production of edible fungi, acaroid mites often occur in the environment polluted by miscellaneous bacteria. Because of their activities, the miscellaneous bacteria are enlarged and the healthy fruiting bodies rot. Acaroid mites can also directly feed on the mycelium of Pleurotus ostreatus, resulting in yield reduction or even loss of harvest. Morphological characteristics: the adult length of male mite is 240 rain 320 microns, and the adult length of female mite is 350 rain 650 microns, the body is colorless, the legs and feet are yellowish to reddish brown, and the back end is obtusely round.

Covering sediment can cure mixed bacteria of Pleurotus ostreatus
Miscellaneous bacteria pollution often occurs in the process of Pleurotus ostreatus cultivation, especially in the high temperature season. Most of these miscellaneous bacteria are aerobic, resistant to high temperature and high humidity, and can be prevented by covering silt. the specific techniques are introduced as follows: 1. Control of miscellaneous bacteria of Pleurotus ostreatus planted in bed. When Pleurotus ostreatus is contaminated by miscellaneous bacteria in big bed cultivation, the cause of pollution should be found out first. The common causes are sudden high temperature, water inflow into the material, unclean surrounding environment, insect pests and so on. According to the specific situation, remove the pollution source, and then treat the contaminated Pleurotus ostreatus as follows: sporadic miscellaneous bacteria on the material surface, use thick lime.
