摘要:

为研究摘薹前后不同施肥量对油菜产量和品质的影响,2023—2024年在兰溪市开展相关试验,并将油菜薹制作成梅干菜对其营养成分进行检测。结果表明,摘薹比不摘薹的油菜生育期明显延迟,株高降低,油菜籽蛋白质含量增加。随着摘薹前后施肥量的增加,生育期相应延迟,一次分枝数小幅增加,单株角果数无明显变化规律,菜籽产量整体呈增加趋势。综合来看,摘薹前5 d或摘薹后当天,每667 m2使用尿素≥7.5 kg时油菜籽产量高,油菜田的综合效益高。油菜薹梅干菜具有较高的营养价值,值得进一步推广。

Abstract:

To study the effects of different fertilization dose before and after topping on the yield and quality of rapeseed, a related experiment was conducted in Lanxi City from 2023 to 2024. The rapeseed shoots were processed into dried pickled vegetable, and their nutritional components were analyzed. The results showed that topping delayed the growth period of rapeseed, reduced plant height, and increased the protein content of rapeseed. As the fertilization dose increased before and after topping, the growth period was correspondingly delayed, the number of primary branches slightly increased, the number of pods per plant showed no clear trend, and the overall rapeseed yield tended to increase. In summary, when urea application was ≥7.5 kg per 667 m2 either on 5 days before topping or on the day of topping, the rapeseed yield was higher, and the comprehensive benefits of the rapeseed field were improved. The dried pickled vegetable made from rapeseed shoots have high nutritional value and are worth further promotion.

Key words: topping, fertilization dose, rapeseed, yield, quality, dried pickled vegetable
