蘑菇在生长过程中除发生真菌、细菌和病毒性病害外,还常因气候不适和管理不善而发生生理性病害、现将常见的几种生理性病害的成因及其预防方法简介如下。 1.空根白心菇:菇房喷水少,湿度小,覆盖层含水不足,子实体得不到充足的水分,菌柄产生白色髓部,甚至空心。适时喷水,出菇期菇房保持在85％以上的湿度,可预防空根白心菇的产生。 2.水锈斑菇:每次喷水后,未及时打开门窗通风换气,菇房湿度过大,蘑菇表面出现小水滴,时间一长,就形成铁锈色的斑点。预防的措施主要是保持室内空气新鲜,喷水后打开门窗0.5—1小时。 3.红根菇:出菇前高温阶段用水过多,覆土层含水量过大,或栽培培养料偏酸,或追施葡萄糖过
Mushrooms in addition to the growth process in the occurrence of fungal, bacterial and viral diseases, but also often due to climate discomfort and poor management of physiological diseases occur, the common causes of several physiological diseases and prevention methods are outlined below. 1. Empty root white mushroom: Mushroom room spray less humidity, lack of coverage of water, fruiting bodies do not get enough water, stipe stalks produce white pith, or even hollow. Timely water, fruiting mushroom house maintained at more than 85% humidity, can prevent the root of white mushrooms. 2. Water rust mushrooms: After each spray, did not promptly open the doors and windows ventilation, mushroom room humidity is too large, mushrooms appear droplets on the surface, over time, the formation of rust-colored spots. Prevention is mainly to keep the indoor air fresh, open the doors and windows after spraying 0.5-1 hours. 3. Red mushrooms: fruiting stage before fruiting too much water, overburden moisture content, or cultivation of culture material partial acid, or topdressing glucose
