三门峡市位于豫西丘陵山区,油菜是当地主要油料作物之一,由于干旱、品种退化、管理粗放,致使油菜产量长期低而不稳,平均亩产仅为78kg。为了充分挖掘增产潜力,针对油菜生产的主要限制因素,开展试验研究,认真总结生产实践,形成了适于丘陵旱地的栽培技术模式,在生产上推广应用,增 Sanmenxia City is located in the hilly area of ​​western Henan. Rape is one of the major oilseed crops in the region. Due to the drought, the varieties are degraded and the management is extensive. As a result, the yield of rapeseed is low and unstable for a long time, with an average yield of only 78kg per mu. In order to fully tap the potential of yield increase, a pilot study was conducted on the main limiting factors of rapeseed production, the production practices were conscientiously summarized and a cultivation technology model suitable for hilly drylands was formed, which was popularized and applied in production.
