将诸葛菜作为油料作物在成都地区进行了驯化栽培，就栽培措施对诸葛菜菌核病发生的影响进行了分析研究。结果表明，播种期对诸葛菜菌核病的发生影响极为显著，三个播期间诸葛菜菌核病病情指数差异均达极显著水平，播种越早，发病越严重。密度、施氮量对诸葛菜菌核病发病影响不显著，但播期、密度和施氮量之间的交互作用显著。
The Zhuge vegetables as oil crops were domestically cultivated in Chengdu. The effects of cultivation methods on the occurrence of S. Sclerotiorum were analyzed.
