Abstract: In this paper, randomized block experiment are adopted. The effe ls of several different types of foliar fertilizes on
the economic characters and seed yield of oil flax in dry land were compared by field experiments. The results show that the
Brassinolide-gibberellin has certain promoting effect on oil flax vegetative growth. Plant height increased 6.034: potassium
dihydrogen phosphate urea can significantly improve the oil lax seeds per fruit, increased 7.93%: Guoguang dilute biotin
bios and KI PO urea treatment can significantly improve 1000-seed weight of oil flax, increased 5.49%, 4.14%,3.950
Guoguang dilute biotin and KH P0 +urea treatment on seed yield reached 1 446.22 k/hm and 1433.87 kg/m
respeetively, increased by 19.02 and 18.00. The increased production was significant. It was proved that spraying folia
fertilizers containing amino acids or large elements on oil flax seed can effectively promote the grain formation and filling
ss of flax. and increase 1000-seed weight and seed yield of oil flax. It has a significant effect on the reduction (due to
the removal of fertilizers of yield in the late stage of birth
