摘　　要：为了进一步分析杂交油菜在不同施肥水平下的丰产性，筛选出最理想施肥基数，为高产攻关创造有利条件，为大面积油菜生产获取高产提供科学依据。通过2011_2012年在云南保山市隆阳区金鸡乡进行杂交油菜BB控释肥栽培试验，对其参试的‘云油杂10号’进行5个处理的肥效效应研究。结果表明：同一品种在相同的管理条件下，5个不同施肥水平处理小区实收产量在606．66-3222．5kg／hm2之间，其中，以全生育期施肥总量尿素675kg／hm2，普钙750kg／hm2，硫酸钾300kg／hm2，,硼肥22．5kg／hm2（底肥：提苗肥：壮苗肥：蕾苔肥=18．5：30：34．3：17．2）的处理产量最高，可作为类似云南隆阳区生态气候油菜高产区大面积推广应用。BB控释肥释放时期提早释放20-25天，增加控释肥用量150kg／hm2，就能达到预期的节本增效效果。To further analyze the high-yielding qualities of hybrid rape under different fertilizer application levels, the experiment was conducted to screen an optimal basic number of fertilization in order to create favorable conditions for high-yielding and provide theoretical basis for large areas of rapeseed production to obtain a high yield. ＇Yunyouza 10＇, a new hybrid rape cuhivar, was selected as materials to study effect of 5 different fertilizer application levels on the yield of hybrid rape under the same management condition from 2011 to 2012 Jinji Town of Longyang District in Baoshan, Yunnan Province. The results showed that plot yields were between 606.66 kg/hm2 and 3222.5 kg/hm2, 750 kg/hm2 calcium superphosphate, 300 kg/hm the output was the highest when 2 potassium sulphate and 22.5 whole growing period, or 18.5% base fertilizer, 30% and 17.2% peduncle growth fertilizer. In Longyang using 675 kg/hmz carbamide, kg/hm2 boron fertilizer in the seedlings growth fertilizer, 34.3% strong seedling fertilizer District and the climate similar hybrid rape high-yielding areas in Yunnan Province, the results might be useful for application in large area. If the controlled-release BB fertilizer nutrition was given out 20 days to 25 days ahead of time and increasing 150 kg/hm2 under 600 kg/hm2 the controlled-release BB fertilizer conditions, the anticipated high efficient results could be attained.
