Abstract: In this research, we took field chrysanthenmum in Sanping Farm Practice Base in Xinjiang Agricultural University as the experiment material, to study the effect of foliar spraying KH2PO4 on Coreopsis tinctoria growth and yield. Spraying 0.5% KH2PO4 in July has the most significant effect on growth and yield; spraying 0.3% KH2PO4 in August has the most significant effect on plant traits and yield. As a result, the effects of spraying 0.5% and 0.3% KH2PO4 on the leaves of Coreopsis tinctoria at different times are most obvious and have time differences.
