摘要
采用再裂区设计,研究了4个不同播期、4种密度和4种尿素用量对皖油29产量的影响。试验结果表明,播期、密度和施氮量显著地影响油菜产量;播期和施氮量互作、密度和施氮量互作对油菜产量均产生影响,达到极显著水平;皖油29在六安种植适宜播期为9月底至10上旬、种植密度以37.5～45万株/hm2、尿素用量以375～450kg/hm2为宜。
The effect of four sowing dates , four plant densities and four nitrogen application amounts on rapeseed yield by split - split plot design. The results indicated that sowing date , plant density and nitrogen application a- mount affected rapeseed yield very significantly. The interaction of plant density and nitrogen application amount affected rapeseed yield very significantly. The interaction of sowing date and nitrogen application amount affected rapeseed yield very significantly, too. The suitable sowing date was the end of September , the planting density was 375,000-450,000 plant/hm2 and Urea application amount was 375 -450 kg/hm2, the highest yield was obtained in Wanyou 29.
