In order to study effects of different tillage methods on soil and water conservation(SWC) and soil carbon stock in red-soil slope land in Southern China,field experiments were carried out in the representative area named Jiangxi Eco-science Park of SWC to investigate the surface runoff,sediment,total organic carbon(TOC) and carbon pool index(CPI) of soils in contour strip intercropping,downslope strip intercropping and clean tillage in orchards with the data of five-year agriculture measurement.The results indicated as follows:(1) Compared with the control(CK),runoff reduction rates of the three measures varied between 21.16% and 75.32%,and sediment reduction rates of them varied between 38.08% and 80.57%.It showed that these agricultural measures have great effects on reduction of runoff and sediment with a descendant order of contour strip intercropping,downslope strip intercropping and clean tillage.(2) Compared with CK,soil TOCs and CPIs of contour strip intercropping,downslope strip intercropping and clean tillage increased by 37.24% to 6.34% and 35.23% to 55.34%,respectively.The results also showed that these agriculture tillage measures have increased soil C and followed a descendant order of downslope strip intercropping,contour strip intercropping and clean tillage.(3) These results indicated that strip intercropping has better benefits than clean tillage and can be applied widely in red-soil hilly region.
