| 摘 要： | 以汉油8号为材料,研究不同栽培密度对机直播油菜产量和抗病性(菌核病)的影响。结果表明:当栽培密度在30万~36万株/hm~2范围时,汉油8号可以取得较高产量(210.04~215.91 kg/667m~2);继续增加密度,油菜菌核病发病严重,倒伏明显,对产量有直接影响,也加大了机械化收获的难度。从经济角度来看,建议机直播油菜汉油8号的最适栽培密度为30万~36万株/hm~2。

Effects of Plant Density on Yield and Disease-resistance of Mechanical Direct Seeding Rape Hanyou No.8 |

| Abstract: | Taking Hanyou No.8(Brassica napus) as material, the ifeld experiments were conducted to study the effects of plant density on yield and disease-resistance.The results showed that the highest yield obtained when the planting density was from 30×104 to 36×104plants per hm2, Above 36×104 plants per hm2, rape sclerotium disease increased seriously and lodging was obviously , which deceased the yield of rape and effected its mechanized harvesting. So it was suggested that the proper plant density of rape was from 30×104 to 36×104 plants per hm2. |
