In winter, the temperature is low, and there are three things to note when planting greenhouse pleurotus in winter:
The first is the use of low-temperature varieties of Pleurotus ostreatus: if cultivated high-temperature varieties of Pleurotus ostreatus in the winter, it will cause "discomfort" of Pleurotus ostreatus, which is mainly manifested as slow development of bacteria, late mushrooming, and even lack of fungus and mushroom. 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.
The second is to choose a place with good ventilation conditions: If you choose to be in a dark, poorly ventilated room, or choose to grow mushrooms in an unsanitary place, you may easily cause contamination with bacteria. The performance of Pleurotus ostreatus is not normal, or even completely scrapped; Although it is difficult to produce bacteria, but because of the high carbon dioxide content of the fruit during the period of victimization, resulting in can not mushroom or mushroom formation. Therefore, when choosing a mushroom cultivation site, you should choose a clean place with good ventilation and scattered light.
The third is to choose a clean, non-agglomerated culture material: if a raw material that has been contaminated and caked is used to cultivate Pleurotus ostreatus, or when nutrients are formulated, an excess of urea or other fertilizers are added to the material to supplement the nitrogen source. It will cause a large area of ​​pollution, resulting in not mushroom or slow mushroom, so we must first choose a clean, non-agglomerated culture material, and at the same time, we must pay attention to only add a certain amount of urea in the fermentation of stuffed mushrooms, and raw materials Cultivation is not free to add urea or other nitrogen fertilizers.
