The effects of B and Zn combined application on quality and yield of Suyou 4 were studied with the method of leaf application of micro-fertilizer in flowering stage.The results showed that leaf application of B and Zn compound micro-fertilizer could significantly increase oil content in rapeseed and protein content in rape cake and meal(being increased by 2.27% and 2.42% resp.),increase linoleic acid content and yields of rapeseed,oil and protein of rap(being increased by 4.75%,7.02%,9.45% and 9.61% resp.),increase silique numbers per plant,seed number per pod and 1 000-seed weight of rap,and decrease its erucic acid content(being decreased by 18.88%).
