摘要: 为探讨我国不同产地的秸秆腐熟剂对寒地黑土区的玉米秸秆腐熟和土壤理化性状的影响,采用田间框栽和微区试验法研究3种秸秆腐熟剂对黑龙江省玉米秸秆降解率和土壤肥力的影响.结果显示,北京正农农业科技有限公司的秸秆腐熟还田专用菌剂(30 kg/hm2腐熟剂与45 kg/hm2尿素混用撒施)和山东金山生物工程有限公司的金山生物-秸秆快腐剂(7.5 kg/hm2与45.0 kg/hm2尿素混用喷施)180 d后玉米秸秆降解率达70%以上,对土壤pH值、全氮、碱解氮、速效磷、有机碳和有机质无明显影响,但能提升土壤速效钾含量,分别较对照高6.23%和7.94%.2种秸秆腐熟剂降低土壤容重分别为0.10,0.12 g/cm3.北京正农腐熟剂可增加土壤含水量,较对照高1.4个百分点.所以2种秸秆腐熟剂能加快黑龙江省黑土区玉米秸秆的腐解速度,且有助于改善土壤理化性状.

关键词: 玉米秸秆, 腐熟剂, 降解率, 土壤肥力

Abstract: In order to explore the effect of different straw-decomposing agents from different producing areas on degrading efficiency of maize straw and soil physical and chemical properties in cold and black soil area in China,a frame experiment and micro plot experiment of field were used to study.The results showed that degrading efficiency of maize straw were better than control,above 70% with straw-decomposing agents of Beijing Zhengnong agri-Tech.Co.,Ltd.and Shandong Jinshan bio-engineering Co.,Ltd..The change of soil pH value,total nitrogen,alkali-hydrolyzale nitrogen,available phosphorus,organic carbon and organic matter weren't significant,but the contents of available potassium in the soil with two species of straw decomposition agent were increased,higher 6.23% and 7.94% than control,respectively.Soil bulk density were reduced 0.10,0.12 g/cm3 by the two species of straw decomposition agents,and soil water content was increased 1.4 percentage points than control with straw-decomposing agents of Beijing Zhengnong agri-Tech.Co.,Ltd.Therefore,maize straw were degraded faster by the two species of straw decomposition agents in Heilongjiang Province,and which were in favor of improving physical and chemical properties of soil.

Key words: Maize straw, Decomposition agent, Degrading efficiency, Soil fertility
