Abstract
[Objective] The aim was to study the effects of conservation tillage on soil respiration and summer maize yield in the arid areas,to provide technology for summer maize field in the arid areas of Northwest.[Method] The mouldboard plough(CK),zero tillage with residue(NTS),chisel plough with residue(CTS) and rotary tillage with residue(RTS) treatments were designed.[Result] The results showed that CO2 emission rate was in the order: RTSCKNTSCTS,CTS treatment significantly increased spike numbers and grains per spike(P0.01).CTS,NTS and RTS increased yield by 24.44%,6.96% and 9.17% compared with CK,respectively.[Conclusion] The chisel plough with residue(CTS) is more suitable plough method for autumn maize in the arid area of Northwest.
