摘要: 为完善半干旱区秸秆还田技术,构建适宜当地农业生产条件的秸秆还田快速腐解技术模式,采用尼龙网袋法研究秸秆腐解菌剂种类和尿素、有机肥用量对秸秆腐解率、腐解速率和玉米产量的影响。结果表明,秸秆还田配施尿素75 kg/hm2和有机肥45 t/hm2可显著提高秸秆腐解率和腐解速率(P<0.05),增加玉米产量(11.84%,P<0.05);在5种秸秆腐解菌剂中,以吉林省农业科学院所制菌剂效果较好,能显著促进秸秆腐解(P<0.05),增加玉米产量(1.34%,P>0.05)。

Abstract: : This experiment studied the kinds of straw decomposing agents and the applying amounts of urea and organic fertilizer on the decomposition ration, decomposition rate and maize yield with nylon mesh bag method, in order to improve the technology of returning straw in semi-arid and construct the returning straw model of accelerating decomposition suitable for local production conductions. The results showed that the proper applying amount of urea 75 kg/hm2 and organic fertilizer 45 t/hm2 could significantly promote straw decomposition ration and decomposition rate(P<0.05), and its maize yield increased 11.84% (P<0.05). The straw decomposing agent from Jilin Academy of Agricultural Sciences had better effects, accelerated decomposition (P<0.05) and its maize yield could significantly increase 1.34% (P>0.05).

Key words: maize straw returning, accelerating decomposition, decomposing agents, urea, organic fertilizer, semiarid area
