一、病害防治 1、红银耳:银耳子实体变红、腐烂,最后失去再生能力而萎缩。防治法:(1)控制培养温度,使它在25℃以下;(2)工具用0.1％高锰酸钾消毒;(3)及时消除和处理染病耳袋。 2、猝倒病:主要侵染菌柄,染病后的菌柄髓部萎缩变成褐色。病菇早期与健康菇外形上无大的区别,只是部分菌盖色泽变暗,菇体停止生长而变成僵菇。防治法:(1)实行土壤消毒;(2)病区喷铜铵溶液(1份硫酸铜加1份硫酸铵,再稀释300倍);(3)喷托布津或多菌灵500倍液。 3、褐腐病:只感染蘑菇子实体。子实体分化前感病会形成似硬
First, disease prevention and treatment 1, red tremella: Tremella fruiting bodies turn red, decay, loss of regenerative capacity and finally shrink. Prevention and control methods: (1) control the incubation temperature, so that it is below 25 ℃; (2) tools with 0.1% potassium permanganate disinfection; (3) promptly eliminate and handle sick ear bags. 2, damping off disease: The main infection stipe, after the infection of the stipe pulp atrophy turned brown. Early mushrooms and healthy mushrooms no big difference in appearance, but part of the color of the lid darken, mushroom body stop growing and become mushrooms. Prevention and treatment methods: (1) the implementation of soil disinfection; (2) ward spray copper ammonium solution (1 copper sulfate plus 1 part of ammonium sulfate, and then diluted 300 times); (3) spray cloth Bujin or carbendazim 500 times. 3, brown rot: only infected with mushroom fruiting bodies. Before fruiting bodies differentiate, the disease will form a stiff shape
