摘　　要：为探讨秸秆还田方式对土壤速效磷和玉米产量的影响,设置秸秆粉碎还田(SCRT)、秸秆覆盖还田(SCR)和秸秆不还田(SNR)3个处理,调查各处理的土壤速效磷含量和玉米叶片叶绿素相对含量(SPAD值)、植株干物质量及产量情况。结果表明,与SNR相比,SCRT和SCR的土壤速效磷含量、叶片SPAD值和植株干物质量显著提高,产量分别提高0.56%和8.32%。秸秆粉碎还田方式能够促进玉米植株积累的有机物向籽粒转移,从而获得更高产量。In order to explore the effects of straw return methods on soil rapidly available phosphorus and summer maize yield,three treatments of straw crushed and returned to the field(SCRT),straw mulched and returned to the field(SCR)and straw not returned to the field(SNR)were set up to study the effects of different treatments on soil rapidly available phosphorus,relative chlorophyll content(SPAD value)of maize leaves,plant dry matter mass and yield.The results showed that compared with SNR,SCRT and SCR significantly increased the soil rapidly available phosphorus content,leaf SPAD value and plant dry matter mass,and the yield increased by 0.56% and 8.32%,respectively.Straw crushed and returned to the field method could promote the transfer of accumulated organic matter to the grains,so as to obtain higher yield.
