菜油两用油菜品种云油杂2号适宜栽培技术研究

Study on the Suitable Cultivation Technique of Hybrid Rapeseed(Brassica napus L.) for Vegetable and Oilseed,Yunyouza No.2

[目的]探讨适宜菜油两用油菜品种(Brassica napus L.)云油杂2号的栽培技术。[方法]选用云油杂2号杂交品种进行育苗移栽,进行不同密度、播种期、打薹时期正交试验。[结果]密度在12万株/hm2,9月26日播种,现蕾期摘薹综合经济效益最高,产值19 056.75元/hm2;其次是密度在9万株/hm2,9月26日播种,现蕾期摘薹综合经济效益好,产值16 545.90元/hm2;第3是密度在15万株/hm2,9月26日播种,现蕾期摘薹综合经济效益好,15 190.80元/hm2;最低是密度在12万株/hm2,10月16日播种,抽薹后12～15 cm摘薹综合经济效益最低,5 450.85元/hm2。[结论]云油杂2号最佳栽培技术是密度12万株/hm2,9月中下旬播种,现蕾期摘薹综合经济效益最高。

[Objective] The aim was to discuss the suitable cultivation technique of hybrid rapeseed for vegetable and oilseed,Yunyouza No.2.[Method] Rapeseed hybrid variety Yunyouza No.2 seedlings was raised and transplanted,then conducted on the orthogonal test of different density,sowing time,bolting date.[Result]When the cultivation technique was as follows： density 12 × 104 plants per hectare,sowing time September 26,picking bolt at budding stage,the comprehensive economic benefit was the highest of 19 056.75 CNY per hectare;the next was the cultivation technique treatment of density 9 × 104 plants per hectare,sowing time September 26,picking bolt at budding stage,and its comprehensive economic benefit was 16 545.90 CNY per hectare;the third was the cultivation technique treatment of density 15 × 104 plants per hectare,sowing time September 26,picking bolt at budding stage,and its comprehensive economic benefit was 15 190.80 CNY per hectare;the lowest was the cultivation technique treatment of density 12 × 104 plants per hectare,sowing time October 16,picking after bolt height 12-15 cm,and its comprehensive economic benefit was 5 450.85 CNY per hectare.[Conclusion]Yunyouza No.2’best cultivation technique is that： density is 12 × 104 plants per hectare,sowing time is the second and third ten days of September,picking bolt at budding stage,and its comprehensive economic benefit is the highest.
