| Abstract: | The crop production trends in Langzhong , Nanbu and Xichong counties, in the Jialing River basinwere analysised. The three counties had the same 6 main crops, i.e. rice, wheat, sweetpotato, maize, cotton and rape,and each county had its own peculiar crop. Notable changes had taken place in sowing area of the 6 main crops from 1949to 1985. Among them, maize had increased most obviously in sowing area since the midle 70s. Land races were generallycultived before 1949. After that, spreaded races of the main crops were replaced several times. The causes of the replacement were analysised. The next tactics of crop production was discussed. |
