总的堆料时间越短,保存的原料越多,堆料的产菇能力越强。若前发酵期为13或35天,初始氮含量对后发酵期长短影响很少或无影响。若前发酵期为3天,由于存在游离氨,高氮培养料——麦秸1000公斤、腐熟褥草鸡粪450公斤、加糖蜜的纤维粉225公斤、石膏60公斤、水5360公斤——的后发酵期增至13天。然而总的堆料期仍以前发酵期3天的最短,23天的最长。堆料期越长,接种时原始干物质和水分残留量越低。高氮培养料接种时密度显然较高,前发酵期延长,培养料密度有增加的趋势。后发酵期最短的培养料,鬼伞属杂菌较多。影响蘑菇产量的主要因素是初始氮含量。若前发酵期为13或23天,初始氮含量对采菇始
The shorter the total stacking time, the more the raw materials, the stronger the stacking capacity of mushroom production. If the former fermentation period is 13 or 35 days, the initial nitrogen content has little or no effect on the post-fermentation period. If the former fermentation period is 3 days, due to the presence of free ammonia, high-nitrogen culture material - 1000 kg of wheat straw, 450 kg of hen litter, chicken fiber excrement 225 kg, gypsum 60 kg, water 5360 kg - post-fermentation Period increased to 13 days. However, the total storage period is still the shortest three days before the fermentation period, the longest 23 days. The longer the stockpile, the lower the original dry matter and water residues when inoculated. The density of high nitrogen culture material inoculation is obviously higher, the former fermentation period is prolonged, and the density of culture material tends to increase. After the shortest fermentation period of culture material, Coprinus more bacteria. The main factor affecting the yield of mushrooms is the initial nitrogen content. If the former fermentation period is 13 or 23 days, the initial nitrogen content of mushroom mining start
