摘  要：
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。

摘  要：
Two types of double low rapeseed oil cultivars including Huashaung No. 4 and Zhongshuang No.10 were used to study the effects of stem-cutting under different densities, stem-cutting stage and stem-keeping height on yield of rapeseed oil. The effect of popularization and application of "Planting Once and Harvesting Twice"(POHT) was analyzed. The results showed the effect of stem-cutting on yield of rape was significantly different under different densities. The highest yield of rapessed was at 120 000 plants/hm2. The highest yield of fresh stem was at 150 000 plants/hm2. The highest yield of rapeseed and fresh stem of stem-cutting stage was on December 23 th with and the stem-keeping height of 12 cm. The popularization and application of "Planting Once and Harvesting Twice"(POHT) can stabilize the yield of rape, increase significantly the planting benefits and improve stem utilization of the rape.
