不同播期对油菜油肥1号菜薹及鲜草产量的影响

Effects of Different Sowing Dates on Yield of Rape Youfei 1 Stem and Fresh Grass

本研究以油菜品种油肥1号为试验对象,研究不同播期对该品种蕾薹期菜薹产量及盛花期鲜草产量的影响,为薹肥两用技术的推广提供依据。结果表明:油肥1号秋播比春播菜薹产量增加24.80%,但品质差异不大;鲜草产量增加34.10%,且植株养分含量略高。

Taking Youfei 1 as the experimental object to study the influence of different sowing dates on rape stem yield in budding stage and fresh grass yield in flowering period,in order to provide the basis for the promotion of rape stem and fertilizer dual-use technology.The results showed that the Chinese flowering cabbage yield of Youfei 1 sowed in autumn increased by 24.80%compared with that in spring,but the quality difference was not significant;the yield of fresh grass increased by 34.10%,and the nutrient content of plant was slightly higher.
