摘　　要：利用裂区试验设计,对玉米收获后复种油菜的栽培技术与生态效益进行了初步研究。结果表明,复种油菜可延长土壤绿色覆盖时间,控制水土流失,保护生态环境;油菜用作绿肥可提高土壤有机质含量,改良土壤性能。油菜生长速度快,可作为蔬菜开发,对促进农业可持续发展具有重要意义。The preliminary study was carried out on cuhivation and ecological by using split-block experimental design. The results showed that sowing rapeseed benefits of corn-rapeseed rotation after corn prolonged the period of green-plant-cover over the soil, controlled water-soil erosion, protected environment, increased soil organics and improved soil performance as green manure. Rapeseed is a vegetable growing fast and its cultivation can bring profits. The corn-rapeseed cultivation can improve sustainable development of agriculture.
