蘑菇(Agaricus bisporus)含水量在90％以上,因此了解对蘑菇的供水很重要。菇床由两层组成,下层为有机营养基质层,上层是覆盖层。水分占基质重量的65～75％,占覆盖层的55～65％。出菇前后给覆盖层浇水,可增加蘑菇含水量。浇水的程度和时间对蘑菇产量和品质以及干泡病和细菌性斑点病的蔓延有影响。 Kalberer(1983)测定了首批菇从覆盖层和基质的吸水量。在5厘米厚覆盖层的菇床中,子实体水分的33～34％来自覆盖土,其余的来自基质。而薄 Agaricus bisporus contains more than 90% water, so it is important to understand the water supply to the mushrooms. Mushroom bed consists of two layers, the lower organic substrate layer, the upper cover. Water accounts for 65-75% of the matrix weight, accounting for 55-65% of the cover. Mushrooms before and after the watering to the cover, mushrooms can increase water content. The extent and timing of watering have an impact on the yield and quality of mushrooms and the spread of dry blister and bacterial speckles. Kalberer (1983) measured the water absorption of the first mushrooms from the overlay and substrate. In a 5 cm thick mushroom bed, 33-34% of the water in the fruiting body comes from the overburden and the rest comes from the substrate. And thin
