摘要
研究了不同播期、种植密度以及施氮水平对免耕直播油菜产量的影响。结果表明,在鄂东南地区免耕直播油菜适宜播期为10月1-15日,适宜密度为3万-5万株/667 m2,适宜施氮水平为纯氮18 kg/667 m2。
The effects of different sowing dates,plant densities and nitrogen application amounts on yield of no-tillage direct- seeding rapeseed were studied. The results indicated that the optimum sowing date was from October 1 to 15, the optimum plant density was 30 000-50 000 plant/667 m^2, the optimum nitrogen application amount was 18 kg/667 m^2 in the southeast of Hubei province.
