A study of the effects of fertilizer N, P, K and microelement Zn, B on the sunflower Baikuiza No.9 on chernozem was conducted. The results indicated that the sufficient quantity of the special sunflower fertilizer (N, P2O5 and K2O content 45%,ratio of N∶P2O5∶K2O was 1∶2∶1) was 300~400 kg/hm2. The best effectiveness was obtained when Zinc sulfate heptahydrate (ZnSO4·7H2O) and sodium tetraborate (Na2B4O7·10H2O) were 10 kg/hm2 and 5 kg/hm2 respectively.
