摘　　要：分析了秸秆切碎机对秸秆长度、抛撒不均匀度的影响,比较了4种机械组合处理还田秸秆在不同土壤深度的垂直分布特征。结果表明,秸秆切碎机处理秸秆水平分布较均匀;采用液压调幅翻转犁配合秸秆切碎机进行翻埋,秸秆集中分布在10~30 cm土层,以20~30 cm土层最多,混土效果较好。The effects of straw chopper on the straw length and inhomogeneity were studied.The vertical distribution characteristics of returning straw among four kinds of mechanical combination treatments were compared.The results showed that the horizontal distribution of straw was more uniform in treatment of the straw chopper.Straw mostly distributed in soil layer of10 cm to 30 cm,espectivelly 20 cm to 30 cm layer in treatment of hydraulic amplitude modulated reversible plow added straw chopper,the effect of mixing soil was better than others.
