不同播期条件下早熟油菜新品种比较试验研究

Comparison Experiments on Precocious New Rapeseed Varieties Under Different Sowing Dates

为引进适合南昌地区二晚稻田种植且早熟耐迟播的油菜新品种,引进一批早熟油菜新品种,在不同播期试验条件下进行品种比较试验。结果表明:在11月初前的任何时候种植,沣油827生育期短且产量高,适合南昌地区生产;而C868、丰油730、青杂131和282018生育期与德油早1号相当,但耐迟播且产量略高于德油早1号,可适度推广种植,以增加品种多样性,减少品种单一化带来的生产危害。

In order to introduce the new rapeseed varieties,which were suitable for the Nanchang area production and early maturing resistant to late sowing, a group of new rapeseed varieties was introduced, the varieties comparison test of rapeseed was studied. Results were as follows ： compared with Deyouzao 1 ,Fengyou 827 had a shorter growth period and higher yield ,which was suitable for planting in Nanchang. While the C868 ,Fengyou 730 ,Qingza 131 and 282018 ,the growth period of them were equal to Deyouzao 1 ,but they are resistant to late sowing,and yield were slightly higher than D evouzao 1. Therefore, those rapessed varieties could be introduced to increase the diversity of species, reduce the hazard which was brought by a single species.
