摘　　要：通过对秸秆功能演化的分析认为,现阶段以秸秆还田为主要利用方式,并论述了秸秆还田的生态效应。然而,随着大量秸秆覆盖农田地表,对机械播种及作物生长也产生了一定的不利影响。秸秆腐解剂的施用在一定程度上改善了这种不利影响,实例分析了秸秆腐解剂的增产效果。试验表明,施用秸秆腐解剂可加速作物生育进程,作物产量提高20%左右。Through analyzed the function evolvement of straw, the most straw use patterns was return fields at present, which can protect ecological environment in agricultural system. Whereas, with many straw cover soil surfaces, there are many adverse influences, for example, it can baffle mechanical seeding and improve crop development. Many research indicated that effective microorganisms improving those adverse ecological impacts at some extent. Our experiments also proved that effective microorganisms increased crop yields about 20%, result indicated that effective microorganisms could accelerate crop growth.
