摘要
通过随机区组试验研究了播期和氮肥对高芥低硫油菜绵油322产量及品质的影响。结果表明,播期对绵油322的产量影响最大,绵油322在10月19日播种时产量最高;施氮肥分别为150 kg/hm2和300 kg/hm2对产量影响不大,不施氮肥会造成明显的减产。品质方面,播期对含油率和芥酸含量的影响均较大,晚播1期后芥酸含量明显下降,晚播2期后含油率明显下降;氮肥影响芥酸含量,施氮肥150 kg/hm2时芥酸含量较高。
The effects of sowing date and nitrogen fertilizer on yield and quality of high erucic acid and low glucosinolate rapeseed Mianyou 322 were studied. The results showed that the effects of sowing date on the Mianyou 32 yield was significant. Mianyou 322 had the highest yield when it was sown on the October 19. Under the condition of 150 kg / hm2and300 kg / hm^2 of nitrogen, there was little different of yield. No nitrogen caused significant production cuts. The effects of sowing date on the oil content and erucic acid content were relatively strong. The erucic acid content decreased significantly after late sowing stage 1. The oil rate decreased significantly after late sowing stage 2. Nitrogen only affected erucic acid content. Under the condition of 150 kg / hm^2 of nitrogen,the erucic acid content of rapeseed was relatively high.
