1989年,我们利用催腐剂积造速成堆肥新技术进行多点试验、示范。取得了明显效果。一、优点 (一)堆制时间短,效果好利用催腐剂堆肥,改善了微生物活动环境,促进了微生物迅速繁殖,堆内温度升高很快,加速了秸秆腐烂。据试验,堆积后三、四天内堆内温度可上升到55℃以上,最后可达65℃,20天即可完全腐烂。这种方法比氢铵堆肥最高温度可提高5～8℃,且高温持续时间长,缩短堆肥时间一半。 (二)杀灭病菌,减轻作物病害催腐剂堆肥可利用高温杀伤秸秆中大部分有害病菌,减轻秸秆还田带菌量,从而减轻作物病害的发生。 (三)堆肥质量高,增加土壤养分试验证明,小麦亩施250公斤催腐剂堆肥,麦收后取土化验,土
In 1989, we used a series of new technologies for accelerating the compaction of cumulants to carry out multi-point experiments and demonstrations. Obtained a significant effect. First, the advantages of (A) the reactor system is short, the effect is good Use of composting catalyst, improve the microbial activity environment and promote the rapid propagation of microorganisms, rapid temperature rise within the pile, accelerated the decay of straw. According to the test, within three or four days after stacking, the temperature inside the reactor can rise to over 55 ° C, and finally up to 65 ° C, completely decaying within 20 days. This method than the ammonium hydrogen maximum temperature can be increased by 5 ~ 8 ℃, and high temperature duration, shorten the compost time half. (B) to kill bacteria and reduce crop disease Catalytic composting can use high temperature to kill most of the harmful bacteria in straw, reduce the amount of straw returned to the field, thereby reducing crop disease. (C) high-quality composting, increasing soil nutrients Test proved that wheat Kushen 250 kg of compost composting, after receiving wheat soil test, soil
