薄膜接种棚,即用薄膜围罩的形同蚊帐的棚子,它与常规无菌室比,具有造价低、建造容易、拆迁方便等优点。袋栽香菇、银耳等食用菌,用薄膜棚接种,可在培养房进行,接好种的菌袋就地排放培养,不必搬动,而把薄膜棚迁移到别处使用,避免了因搬动菌袋而造成的杂菌污染。但若对接种棚特性不了解,易导致接种污染,造成栽培失败。根据我们近年来的实践与调查表明,薄膜接种棚的特性,主要是由塑料薄膜本身的固有特性所造成,主要有以下三点: 1.室温上升快。这是由于薄膜传热性差、保温性能好所造成的。接种时,由于人体、酒精灯等发出的热量散不出去,聚集在棚内,使棚内温度不断上升,特别是高温季节,温度上升十分迅速。
Film inoculation shed, that is covered with a thin film mosquito net shed, compared with the conventional sterile room, with a low cost, easy construction, demolition and other advantages. Bag mushrooms, white fungus and other edible fungi, with film shed inoculation, can be carried out in the training room, then a good kind of bacteria bags in situ discharge training, do not have to move, and the film shed to migrate elsewhere to avoid the bacteria Bacteria caused by the bag pollution. However, if you do not understand the characteristics of inoculation shed, easily lead to inoculation pollution, resulting in failure of cultivation. According to our practice in recent years and surveys show that the characteristics of film inoculation shed, mainly due to the inherent properties of plastic film itself caused by the following three points: 1. Rise at room temperature. This is due to poor heat transfer properties, insulation performance caused by a good. Inoculation, due to the human body, alcohol lamp and other heat are scattered out, gathered in the shed, so that shed temperatures, especially in hot season, the temperature rose very rapidly.
