摘　　要：选用湖南泰谷公司的秸秆速腐剂,研究常温条件下不同用量秸秆速腐剂对玉米秸秆的腐解效果。采用失重法,设4个处理,分别为:清水(对照)、速腐剂4g、速腐剂6g、速腐剂8g,。结果显示,秸秆腐解数量随速腐剂用量增加而增加。180 d 8 g速腐剂的秸秆腐解率最大,达38.1%,比不加速腐剂的对照增加24.9%。腐解剂在使用20 d腐解速度最快,腐解效果最好。Using a fast decomposition agent produced by Hunan Taigu Company and weight lose method adopted, effect of applying dosage on decomposition of maize straw was studied at normal atmospheric temperature. There were 4 treatments tested： （1） water CK, （2） 4g fast decomposition agent, （3） 6g fast decomposition agent and （4） 8g fast decomposition agent. The results showed that the decomposition rate of maize straw was increased with the increase of dosage of fast decomposition agent. After 180d, the best effect was gotten in the 8g fast decomposition agent treatment, and the decomposition rate of maize straw was 38.1%, which was 24.9% higher than the CK. The decomposition speed was the highest and the decomposition effect was the best when trial time reached 20days.
