油菜田蜜蜂授粉与病虫害绿色防控技术集成研究

Study on Integration of Bee Pollination,Pest and Disease Green Prevention and Control Technology in Rape Fields

[目的]有效控制油菜病虫害的同时保护蜜蜂授粉安全。[方法]2014—2016年在巢湖进行为期3年的油菜花期蜜蜂授粉与病虫害绿色防控技术的集成试验研究。[结果]油菜田蜜蜂授粉与花期使用40%菌核净防治菌核病能明显提高油菜单株角果数及油菜籽产量,油菜籽含油率增加,且对授粉蜜蜂安全,生产出的油菜籽和蜂蜜基本无农残。[结论]该技术可作为"油菜田蜜蜂授粉与病虫害绿色防控技术集成"予以大面积推广应用。

[Objective] The research aimed to effectively control the diseases and insect pests of rape and protect the bee pollination safely. [Method] The integrated experiment on bee pollination and pest and disease control in rape during the three years of 2014-2016 in Chaohu was conducted. [Result] The results showed that using 40%dimethachlone to control the Sclerotinia sclerotiorum in rape field in the bee pollination and flowering period could significantly increase the number of pods per plant and the yield of rapeseeds, the rapeseed oil content increased, and it was safe for pollinated bees. The produced rapeseed and honey had almost no pesticide residues. [Conclusion] The technology could be widely used as "integration of bee pollination, pest and disease green prevention and control technology in rape field".
