“301”菌剂，又称“301”秸秆快速堆腐剂，是由中国农科院原子能研究所研制开发的用于堆腐秸秆肥的新型菌剂。利用此菌剂堆腐秸秆时能产生大量纤维素酶，在较短的时间内将各种作物秸秆堆制成有机肥。一般情况下，夏天需4周时间，冬天需6周时间，即能将各类秸秆堆制成优质有机 “301” bacterium agent, also known as “301” rapid accumulation of straw, is developed by the Chinese Academy of Agricultural Sciences Institute of atomic energy for composting straw fertilizer new fungus. When using this fungicide composting straw can produce a lot of cellulase, in a short period of time will be a variety of crop straw heap into organic fertilizer. Under normal circumstances, the summer takes 4 weeks, winter takes 6 weeks, that is, all kinds of straw can be made into high-quality organic
