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
