[Method] Planting benefit of five kinds of planting patterns of Ditian6 were studied. They were one cropping of sweet corn per year,two cropping of sweet corn per year, multiple sowing of wheat and sweet corn, intercropping of sweet corn and vegetables（potatoes, peppers）. [Result] Planting benefit of two cropping of sweet corn in a year, multiple sowing of wheat and sweet,intercropping of sweet corn and vegetables（potatoes, peppers） were higher than that of sweet corn monoculture. The benefit of two cropping of sweet corn per year was the highest, which was 93 937.5 yuan/hm^2. The pure income increase was 41 610 yuan if the average investment of 18 480 yuan/hm^2 was eliminated. Compared with wheat monoculture, the benefit of multiple sowing of wheat and sweet increased39 060 yuan/hm^2. The pure income increase was 25 500 yuan if the average investment of 13 560 yuan/hm^2 was eliminated. The planting benefit of intercropping of sweet corn and potato was 71 460 yuan, and that of intercropping of sweet corn and pepper was 63 750 yuan. [Conclusion] There were extremely significant differences among the economic benefits of 5 planting patterns of sweet corn. According to local actual situation, farmers can choose the most suitable pattern to improve the planting efficiency of the sweet corn.展开更多
