Pleurotus ostreatus grows slowly, mainly due to the following three reasons: 1. Incompatibility of strains and seasons. If the high-temperature varieties of Pleurotus ostreatus are cultivated in the winter, it will cause the “discomfort†of Pleurotus ostreatus, which is mainly manifested as slow bacterial growth, late mushrooming, and even no bacterial growth. Therefore, winter cultivation of Pleurotus ostreatus should choose low-temperature varieties. Similarly, in the growing season of spring and autumn oyster mushrooms, we must choose high-temperature varieties. 2. The environment of mushroom farm does not cause "poisoning". If you choose to be in a dark, poorly ventilated room, or choose to grow mushrooms in unsanitary places, these are the causes of bacterial contamination. The toxins secreted by the bacteria inhibited the growth of edible mushrooms and appeared "poisoning symptoms". They showed that the oyster mushroom could not grow normally or even completely scrapped; while some of them were forced to grow bacteria, they were damaged due to excessive carbon dioxide content during fruiting period. , It can not produce mushrooms or malformed mushrooms. Therefore, when choosing a mushroom cultivation site, you should choose a clean place with good ventilation and scattered light. 3. Culture material contamination. If you choose to use contaminated, agglomerated raw materials to grow Pleurotus ostreatus, or add nutrients to supplement the nitrogen source and add too much urea or other fertilizer to the material, it will cause large-scale pollution, resulting in not producing mushrooms or hair. Mushroom slow. Therefore, we must first select a clean, non-agglomerated culture material; Second, we must pay attention to only add a certain amount of urea when stocking fermented mushroom, and raw material cultivation is not free to add urea or other nitrogen fertilizer. In addition, the use of culture materials that are stored for an extended period of time and are acidic (it can smell sour after being mixed) will also cause slow mushroom growth and should be avoided.
