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 new varieties of rape suitable for sowing two crops of rice in Nanchang area and being early maturity and late sowing, a batch of new varieties of precocious rape were introduced and tested under different sowing date. The results showed that when the plant was planted at any time before November, Soybean Oil 827 had a short growth period and high yield, which was suitable for the production in Nanchang. However, the growth period of C868, Fengyou 730, Qingza 131 and 282018 was equivalent to that of Deyang No.1 Delayed sowing and yield slightly higher than the German oil as early as 1, may be appropriate to promote the planting, in order to increase the diversity of varieties and reduce the production of a single species hazards.
