有部分菇农喜欢在平菇培养基中添加尿素,提高含氮量,其实尿素对平菇菌丝生长有直接抑制生长的危害性。食用菌菌丝生长的过程中,在酶的分解作用下,尿素分解成氨气与二氧化碳,直接阻止菌丝的生长。据有关试验,培养基中添加尿素会推迟出菇期,量越大现象越明显。由此可见,添加少量尿素需延长培养料的发酵时间后方可栽培,增加含氮量,建议添加适
Some mushroom farmers like to add urea in the mushroom medium, increase nitrogen content, in fact, urea has a direct inhibitory effect on the growth of Pleurotus ostreatus growth. Edible mushroom mycelium growth process, the decomposition of the enzyme, urea decomposition into ammonia and carbon dioxide, directly to prevent the growth of mycelium. According to the test, adding urea in the medium will delay the fruiting period, the greater the amount, the more obvious the phenomenon. Thus, adding a small amount of urea to extend the fermentation time of the culture material before cultivation, increase nitrogen content, it is recommended to add appropriate
