摘  要:
为减少油菜生产的劳动力投入,提供高效的杂交油菜栽培技术应用于生产,以优质杂交油菜黔油22号为研究对象,构建了该品种稀植栽培产量与栽培因子间的数学模型,得出了该品种在贵阳市稀植栽培产量大于180kg/667m2的优化方案:纯N为18.13~21.66kg/667m2,播期为9月14—20日,密度为3 453~3 940株/667m2。

摘  要:
To reduce the investment of labor force and increase the efficiency of rapeseed production,a mathematical model about yield and planting factors for Qianyou 22 was constructed.To obtain yield over 180 kg/667m2 in Guiyang at low density,the best planting models of hybrid rapeseed Qianyou 22 were that amount of N was in the range of 18.13~21.66 kg /667m2,suitable sowing time was September 14~September 20,and suitable planting density was 3 453~3 940 plants/667m2.
