摘　　要：为探索出有利于发挥杂交油菜单株生产优势,研究杂交油菜大面积应用推广的适宜栽培密度,以杂交油菜"黔油22号"为材料,设置了7个不同栽培密度处理。结果表明:当密度达到13000株/667m2时产量最高,达183.3kg/667m2,而当密度高于或低于13000株/667m2时,受群体质量的影响产量下降。In order to explore the advantages of hybrid rape production,Study on suitable cultivation density for wide application and popularization,Hybrid Rape Variety Qianyou 22 is used as test material,7 different cultivation density treatments were set up in the experiment,The results showed that when the density reached 13000/667 m2,the yield was the highest（ 183. 3 kg/667 m2）,when the density was higher than or below 13000/667 m2,the yield declined by the population.
