露地袋栽香菇,在转色出菇期间,经常会碰到因菌筒的腐烂而影响香菇优质高产。现将菌筒腐烂的症状、成因及防治办法简介如下:一、症状及原因(一)菌筒松散解体。菌筒松而无弹性,手触摸即散于畦面,培养料无异味,多发生在菌简开袋转色时或已出了1～2批菇后。主要原因是:在菌简发菌过程中,培养室通气不良严重缺氧;菌丝生长后期产生大量菌温,加上气温高,没有及时进行翻堆散热,由于温度超过33℃以上而使部份菌丝死亡;当气温下降后虽有部分菌丝能恢复生长,但菌筒已变得松软无弹性,重者脱袋即解体,轻者转色后菌皮薄,出了1～2批菇后(?)如通风不良(?)喷水过多也会松散(?)
Open bags planted mushrooms, mushrooms in the color change, often encountered due to the decay of fungi and affect the high-quality mushrooms. Now bacteria tube decay symptoms, causes and prevention methods are as follows: First, the symptoms and causes (A) bacteria tube loose disintegration. Bacterial tube loose and inelastic, hand touch that is scattered in the noodles, training material no smell, occurred in the bacteria Jane open bag color change or has been out of 1 to 2 after the batch of mushrooms. The main reason is: in the course of bacteria, the poor ventilation in the training room was poorly ventilated; a large amount of bacteria temperature was produced in the later period of mycelial growth, and the temperature was high, there was no timely cooling in the coil. As the temperature exceeded 33 ℃, Mycosis died; when the temperature dropped although some mycelium can resume growth, but the fungus has become soft and inelastic, heavy bag that is disintegration, the light after transfer of color thin skin, out of 1 to 2 batches After the mushroom (?) Such as poor ventilation (?) Spray too much will be loose (?)
