Abstract:
It is an important historical task for the tobacco sector to promote tobacco growers' income. The exploration of increasing tobacco growers' income had been carried out in most of the tobacco production areas in China. In this study, planting patterns in Liangshan tobacco growing areas were surveyed and analyzed. The results showed that there were different planting patterns in Liangshan tobacco areas including tobacco-rice rotation, tobacco-garlic rotation, tobacco-viciavillosa rotation, tobacco-buckwheat rotation, tobacco-autumn pea rotation or intercropping, tobacco-wheat intercropping, tobacco-barley rotation, tobacco-rape rotation, tobacco-maize rotation, tobacco-cabbage rotation and tobacco-turnip rotation. Distribution areas of these planting patterns were different because of the differences in altitudes, climatic conditions and production habits in different counties. The economic benefits of different planting patterns differed significantly from each other, with the highest reaching more than 2000 yuan/667 m
2 and the lowest being only about 200 yuan/667 m
2. All of these planting patterns had good social and ecological benefits. The suitable planting patterns for raising tobacco growers' income in paddy-upland rotation areas and dryland rotation areas in Liangshan were put forward on the basis of comprehensive analysis of economic, social and ecological benefits of different cropping patterns.
