Abstract: In order to investigate the economic benefits of the new grain and economic crops planting pattern “rice-garlic-sun cured tobacco”, cost-benefit analysis and economic feasibility analysis of the new pattern, the traditional“rice-tobacco”and“rice-garlic”pattern were conducted. The results showed that compared with the traditional“rice-tobacco”and“rice-garlic”pattern, the multiple cropping index of“rice-garlic-sun cured tobacco”increased by 60%, its total output value increased 55740.4 yuan/hm2 and 40644.5 yuan/hm2, respectively; its net productivity of land increased 45144.0 yuan/hm2 and 43661.9 yuan/hm2, respectively; its net yield of active labor was 34.94% higher than that of the traditional“rice-tobacco”pattern, but was 24.22% lower than that of the traditional“rice-garlic”pattern. Compared with the traditional“rice-tobacco”and “rice-garlic”pattern, net yield of physical labor of the new planting pattern increased by 17.39% and 27.22%, respectively; the increased net benefit rate reached 116.38% and 25.76%, respectively; and the marginal costbenefit rate reached 3.14 and 1.55, respectively. The“rice-garlic-sun cured tobacco”pattern has certain popularization and application value as it is beneficial to improve the utilization of resources and increase farmers’income.
