摘　　要：为推广玉米秸秆还田技术,通过2年田间定位试验,研究了秸秆深翻和免秸覆盖对玉米土传病虫害及产量的影响。结果表明:秸秆还田逐年加重玉米茎腐病发生;丝黑穗病流行年份,免耕-秸秆覆盖较秸秆深翻减轻丝黑穗病危害;玉米螟的危害随还田年限增加逐年加重;秸秆还田增加玉米产量,但在病虫害流行年份免耕秸秆覆盖出现减产。In order to popularize maize straw returning technology,effect of straw deep returning on soil and no-tillage mulch on soil-borne disease,insects and yield of maize were studied through two years of field positioning experiments.The results showed that the straw returning to the field increased the harm of maize stalk rot.During the epidemic years,comparing with the treatment of straw deep returning on soil,the treatment of no-tillage with mulch reduced the harm of head smut.With the increase of straw returnting years,the harm of the corn borer aggravated year by year.The straw returning could increase the yield of maize,but during the epidemic years of diseases and pests,the treatment of no-tillage with mulch would decrease in yield.
