茶新菇,又名茶树菇,是我国近年来新开发比较成功的珍稀食用菌。菌袋污染是茶新菇栽培的难题。这里主要介绍茶新菇菌袋污染原因及控制技术。一、菌袋生产常见的污染源1.绿色木霉。竞争性杂菌之一。其菌丝生长浓密,初期呈白色斑块,逐步产生浅绿色孢子,菌落中央为深绿色,向外逐渐变浅,边缘呈白色;后期变为深黄绿色、深绿色,会使培养基全部变成墨绿色,受其侵染后养分破坏,严重时使培养基全部变成墨绿色,发臭软腐,整批菌种腐烂,固视为无可救药的“癌症”。
New mushroom tea, also known as Agrocybe, is a newly developed rare edible mushroom in recent years in China. Bag bacteria pollution is the problem of cultivation of tea mushrooms. Here mainly introduces the new mushroom bag contamination causes and control techniques. First, the common source of bacteria bags production 1. Trichoderma green. One of the competitive bacteria. The mycelial growth is dense, the initial white patches, and gradually produce light green spores, the colony is dark green, gradually lighten outward, the edge of the white; late into a dark yellow-green, dark green, will make all of the media change Into the dark green, by its nutrient damage after infection, serious when all the media into a dark green, stinky rot, the whole batch of bacteria decay, fixation as hopeless Cancer.
