丹东地区不同复种模式作物产量及经济效益研究

Yield and Benefits Study of Different Multiple Cropping Patterns in Dandong Region

通过对辽东南丹东地区鲜食玉米—白菜、鲜食玉米—萝卜、马铃薯—白菜、马铃薯—萝卜4种充分利用光热资源的复种作物组合模式研究,综合比较不同复种模式产量、成本投入、畅销度、风险性和经济效益等方面的差异,试验结果分析认为鲜食玉米—白菜复种的实际收益较高,但鲜食玉米种植也存在较高风险,建议通过适时早播和合理培肥等栽培措施规避种植风险。

Four groups of high photosynthetic efficiency multiple cropping patterns fresh corn-cabbage,fresh corn-carrot,potato-cabbage and potato-carrot were studied in the southeastern region of Dandong in Liaoning province.Comprehensive comparison of different multiple cropping pattern including yield,costs,popular de-gree,risk and economic benefit,The results analysis proved the income of fresh corn-cabbage is higher,but fresh com planting had higher risk relatively.It suggested to avoid planting risk through timely early sowing and reasonable fertilization.
