LIU Gui-hua,SU Yue,FENG Ze-wei(Guizhou General Station of Popularizing Agricultural Technique,Guiyang,Guizhou 550001,China)  
Favorita,a potato variety with early maturity and good commodity,was tested in winter rice fields of 6 low latitudes areas with high temperature under the no-tillage with rice straw mulch and conventional tillage cultivation patterns to study the effect on its yield.The results showed that the yield and income of the no-tillage with rice straw mulch cultivation pattern increases by 10.34% and 440.22 Yuan/667m2 compared with that of the conventional tillage cultivation pattern respectively,and the output/input ratio and potato commerciality of the no-tillage with rice straw mulch cultivation pattern is higher than the conventional tillage cultivation pattern,which indicates the no-tillage with rice straw mulch cultivation pattern should be popularized in winter rice fields of the low altitudes areas with high temperature.
