Based on the two rotation cycles site-specific experiment， the effects of different tillage and fertilization methods on the nutrient accumulation， yield and fertilizer utilization rate of rapeseed in Chengdu Plain were studied， in order to provide theoretical basis for the efficient management of rape nutrients in Chengdu Plain. Eight tillage and fertilization treatments were set up in the experiment: no tillage without fertilization(NCK)， rotary tillage without fertilization(RCK)， no tillage-spreading without soil cover(NS)， rotary tillage with spreading(RS)， no-tillage with hole fertilization(NHF)， rotary tillage with hole fertilization(RHF)， no-tillage with band placement(NBP)， rotary tillage with band placement(RBP). Results showed: 1)Compared with no tillage， the nitrogen content in the root， stem， branche， silique husks and oilseed of rapeseed increased by 46.9%， 14.0%， 19.3%， 9.5% and 4.2%， while the phosphorus content increased by 65.3%， 34.6%， 17.9%， 7.8% and 4.8%， the accumulation of nitrogen and phosphorus in the whole plant increased by 14.8 ～ 22.5 and 2.1 ～ 2.9 kg·hm-2， respectively， with an average increase of 13.0% and 11.6%( P<0.05). The root nutrient content of rapeseed was sensitive to the difference of tillage methods， and the accumulation and distribution of nitrogen and phosphorus in roots were significantly increased. 2)Compared with broadcast application，the nitrogen absorption and utilization of rape plants in mature stage were significantly improved by applying fertilizer in holes and strips. The nitrogen content of rape root， branche， silique husks and oilseed increased by 34.5%， 36.4%， 31.6% and 12.8% on average. The nitrogen accumulation of the whole rape plant increased by 9.2 ～ 27.4 kg·hm-2， with an increase of 6.9% ～ 18.3%. The response of phosphorus and potassium uptake and utilization to fertilization was less than nitrogen. 3)Compared with no tillage treatment， rotary tillage treatment can improve the oilseed yield and nitrogen use efficiency of rapeseed， which showed the trend of rotary tillage > no tillage and hole fertilization > band placement > spreading. In the treatment of tillage and fertilization， the oilseed yield and nitrogen utilization rate of RHF treatment increased significantly by 16.1% compared with NS treatment， and the apparent nitrogen utilization rate， agronomic utilization rate and partial productivity increased by 36.8%， 13.4% and 16.2%( P<0.05)， respectively. Therefore， rotary tillage and hole fertilization are suitable for high-efficiency production of rapeseed in this area. In the large-scale production of rapeseed， hole fertilization and band application should be selected under the condition of rotary tillage， and hole fertilization is suitable under the condition of notillage. At the same time， rotary tillage and centralized fertilization improved the absorption of nitrogen， phosphorus and potassium in rapeseed， and the current fertilizer application should be further adjusted after straw returning to the field.
