以双低油菜品种华双4号和中双10号为试验材料,研究了不同种植密度下油菜摘薹的效应以及不同摘薹时间和留薹高度对油菜产量的影响,分析了“一菜两用”技术推广应用效果。结果表明,不同密度条件下摘薹,油菜产量表现明显不同,油菜子产量以12万株/hm2最高,鲜菜薹产量以15万株/hm2最高;不同摘薹时间和留薹高度条件下,12月23日摘薹、留薹12 cm油菜子和鲜菜薹产量较高,且菜薹品质好,为最佳摘薹组合;双低油菜“一菜两用”产业化技术的推广应用,实现了油菜平产稳产,显著提高种植效益。
The effects of different rapeseed rapeseed bolting seasons and different bolting time and bolting height on rapeseed yield were studied with two low-rapeseed varieties, Hua Shuang 4 and Zhong Shuang 10 as test materials. Use “technology to promote the application effect. The results showed that the yield of rapeseed was significantly different under different densities. The yield of rapeseed was the highest at 120,000 plants / hm2 and the highest at 150,000 plants / hm2. Under the conditions of different bolting time and bolting height, December 23, bolting, leaving 12 cm rapeseed and sedge sprouting yield higher, and the quality of the vegetable sprouts, picking the best combination of seabuckthorn; double low rape ”a dish dual use " industrialization of the promotion and application of technology , To achieve a stable and stable rapeseed yield, significantly improve the planting efficiency.
