据国家粮油信息中心数据显示,2014年,河南油菜籽产量约为87万t,同比下降12%左右。不仅河南,很多以油菜为主要油料作物的省份,油菜种植面积和产量都在下滑。特别是随着全球气候变暖,河南受到天气变化频繁的影响,油菜产量一直不稳定。为此,详细探讨油菜高产栽培技术,为河南油菜产量的提高提供技术支持。 According to the State Grain and Oils Information Center data show that in 2014, Henan rapeseed production was about 870,000 t, down 12% year on year. Not only in Henan, many provinces that mainly produce rape as their main oil crops have seen declines in rapeseed acreage and output. Especially with the global warming, Henan is subject to frequent changes in the weather, rapeseed production has been unstable. To this end, a detailed study of rape high-yielding cultivation techniques for the improvement of yield of Henan rape to provide technical support.
