香菇杂菌主要有细菌、酵母菌和丝状真菌,是由于高温高湿、培养料发酵变质、pH值调节不当引起的.杂菌孢子通常在24h内萌发,10d内完成整个生活史.链孢霉是最易污染的杂菌之一,生长极快,传播力很强,若管理不当,5d左右整个菌室一片桔黄,造成毁灭性的损失.经过几年实践,我们总结出了杂菌综合防治几项措施,现介绍如下:(一)栽培季节的安排 香菇属低温型变温结实性真菌,栽培要根据香菇菌丝的最适生长温度(23℃～28℃)和子实体生长发育的最适温度(15℃左右)来安排.
Mushrooms bacteria are mainly bacteria, yeast and filamentous fungi, is due to high temperature and humidity, culture material fermentation metamorphosis, pH value caused by improper adjustment .Spores spores usually germination within 24h, 10d to complete the entire life history. Mold is one of the most easily contaminated bacteria, grow very fast, strong spread, if not properly managed, 5d or so the entire chamber a orange, causing devastating losses.After several years of practice, we concluded that the bacteria Integrated prevention and control of several measures, are described below: (A) the cultivation season arrangements Lentinus is a low-temperature temperature-afforestation fungi, cultivation according to mushroom mycelium optimum growth temperature (23 ℃ ~ 28 ℃) and fruiting body growth and development Suitable temperature (about 15 ℃) to arrange.
