Tillage measures and fertilization methods are both important factors affecting crop yield and dry matteraccumulation.The effects of different tillage and fertilization methods onyield，dry matter accumulation and quality ofwinter rapeseed at the mature stage were studied in order to provide theoretical basis for regional highyield，high efficiencyand scientific fertilization of winterrapeseed.The field experiments were conducted in 2017～ 2018 and 2018～2019.Using chuanyou 36 as the experimentalmaterial，two tillagemethods，no -tillage and rotarytillage，as well as three differentfertilization methods，i.e.，holeapplication，band application and broadcast application were setup.Compared withthe controlgroup，fertilization increased the yield by an average of 1679.72 kg·hm -2，with an increase of200.31%；podangle per plant increased by168.34，with an increase of181.99%；dry matter of rape increased by 5593.38 kg·hm -2，with a significant increase of156.69%( P<0.05).The yield，oil production and dry matter accumulation of rapeseed ofrotary tillage with hole application treatment were the highest in all fertilizationtreatments，and the two -year average wassignificantly increased by16.89%，17.39% and 17.03% than that of no -tillage(farmers'habit)(P<0.05).The dry matteraccumulation ofbranches，nut shells and seeds under rotary tillage was28.21%，18.22% and 14.45% higher than that under no-tillage；Under the same fertilizationconditions，theyield，oil production and dry matter of rotary tillage increased by 5.40%～9.29%，1.72%～ 9.53% and 3.73%～9.12% on average.Under the same tillagemethod，the effects offertilization on rape，oil production and dry matter were significantly different，which showed as hole application > bandapplication > broadcastapplication，the average yield of hole application and band application treatments increased by 213.21 and 106.92 kg·hm-2，with an increase of 8.84% and4.43%，respectively，compared with that of hole applicationtreatment.After fertilization，the oil content of rapeseed seed decreased by 2.50%～7.72%，and the decrease amplitude of rotary tillage was greater than that of no-tillage.The protein content of seedincreased.The seed oil yield of hole application under no-tillage treatment increased by 5.98% and 13.17% on average in two years compared with that under band andbroadcast applicationtreatments；and the seed oil yields of hole and band application treatments under rotary tillage treatmentincreased by 7.57% and6.05%，respectively，compared with that under broadcast application treatment.In the plantingarea of Chengdu Plain alluvial soil，rotary tillage combined with fertilizer hole application or band application could better realize high yield and high-efficiency production of winter rapeseed.If no -tillage was adopted in actualproduction，fertilizer application mode of hole application could be adopted.
