采用半夏单作、玉米单作、大豆单作、半夏-玉米间作和半夏-大豆间作5种种植模式，考查整个生产过程中其主要生产资料投入、劳动力投入及产值等主要指标。结果表明，不同种植模式的经济效益差异很大，半夏-玉米间作比半夏单作增收13.1%，比玉米单作增收821.6%，半夏-大豆间作比半夏单作增收17.0%，比大豆单作增收280.0%。合理的间套作模式是中药材生产中值得推广的增益形式。

Authors investigated the economic benefits derived from five growing models, including Pinellia ternata (Thunb.) Breit. monoculture, Zea mays L. monoculture, Pinellia ternata. and Zea mays interplant, Glycine max (L.) Merr. monoculture, and Pinellia ternata and Glycine max interplant. The economic benefits were measured by a range of major indicators, including input of both productive materials and labor force, and output. Study results show that different growing models are significantly different in economic benefits harvested. For example, Pinellia ternata and Zea mays interplant enjoyed an increased benefit by 13.1%, compared with Pinellia ternata monoculture, with an increased benefit of 812.6% against Zea mays monoculture. Meanwhile, Pinellia ternata and Glycine max interplant has registered an enhanced benefit by 17.0%, compared with Pinellia ternata monoculture, and a raised benefit of 280.1% against Glycine max monoculture. Apparently, reasonable mixes makes a good model for increasing the economic benefits of growing Chinese traditional medicine.
