平菇露地生产尽管技术简易,但要获得高产,菇期管理还是至关重要的,主要应注意以下三点,(一)自然透气,适时催菇,发菌结束即进入生殖生长阶段,当见到菌丝穿满畦床边沿、逐渐变浓白时,要搬动压边的土块,松开封闭的农膜,让其适度自然透气,切忌过早支起农膜,否则就不能及时诱发扭结原基;若敞开透气,水分散失严重,不易高产.菌丝扭结现原基的时间因品种而异,同时也与小环境密切相关.让其适度自然透气的目的,在于不受品种、环境条件影响,及时诱发原基.如果发好菌后仍紧闭农膜,CO_2浓
Although it is technically easy to produce mushrooms, it is essential to get high yield and management of mushrooms. It is important to note the following three points: (1) natural ventilation, To the mycelium full brim bed edge, the gradual thickening of the white, the pressure to move the clods to loosen the closed plastic sheeting, let it moderate natural breathe, avoid prematurely plastic sheeting, or can not be timely Induced kinking of the original base; if open air permeability, serious water loss, not easy to produce high yield mycelium twisting primordial base time varies with species, but also closely related with the small environment so that the purpose of moderate natural ventilation is not subject to species, Environmental conditions affect the timely induction of primordia. If the bacteria are still closed after the closure of plastic film, CO 2 concentrated
