摘要
[目的]筛选门源县优质油菜的最佳播种期、最佳种植密度、最佳施肥量和追肥量等大田生产技术参数,总结优质油菜规范化高产栽培技术。[方法]以青杂7号为研究对象,在青海省门源县开展不同播种期、不同种植密度、不同施肥量和追肥量等高产栽培技术模式研究。[结果]适宜播种时间为4月中下旬,播种密度控制在45.0万~52.5万株/hm^2,施肥量以二铵270 kg/hm^2和尿素162 kg/hm^2,追施尿素37.5 kg/hm^2为最佳组合。[结论]合理的栽培措施可显著提高油菜单位面积产量,值得在生产中推广。
[Objective] The aim was to obtain the optimal planting density,fertilization amount and topdressing quantity for high quality rape in Menyuan County,summarize high yield cultivation technique.[Method] With Qingza No.7 as research object,high yield cultivation technique modes of different planting densities,topdressing quantity and fertilization amount in Menyuan County were studied.[Result] The appropriate sowing period was mid and late Apr.,planting density was 45.0 × 104-52.5 × 104 plants/hm2.The optimal fertilizer combination was diammonium 270 kg/hm2,urea 162 kg/hm2,topdressing urea 37.5 kg/hm2.[Conclusion] The appropriate cultivation measure can significantly improve rape yield per unit area,and it is worth popularizing in production.
