摘　　要：以土壤容重、含水量和玉米产量为指标,研究耕作方式对土壤物理性状及玉米产量的影响。试验结果表明:与传统耕作相比,深松使0~40 cm耕层的土壤容重下降8.1%,且生物产量和经济产量均最高,增产7.11%。深松与传统耕作处理间差异显著。Soil bulk density,water content and maize yield was taken as indicators to study the effect of different cultivation method on soil physical characteristic and maize yield.The experimental results showed that:Compared with traditional cultivation,subsoiling could decline soi bulk density of in 0~35 cm plouph layer 8.1%,and subsoiling and no-tillage enhanced water content 4.2%and 5.6%respectively;The biological yield and economic yield by subsoiling were all the highest,which increased production 7.11%compared with traditional cultivation.
