Abstract:
Taking Tagetes erecta as the experimental material,and greenhouse cultivation method was adopted,the effects of foliar application of humic acid fertilizers during the squaring stage of Tagetes erecta on its agronomic traits and physiological indicators were studied,in order to provide reference for the application of humic acid fertilizers in Tagetes erecta field production.The results showed that humic acid water soluble fertilizer (HA) application significantly increased the number of secondary branches and flowers,and the total yield per plant by 16.02% in comparation with the control.Compered to the control,the contents of soluble sugar,soluble protein and chlorophyll in the leaves of T.erecta increased by 10.70%,7.02% and 7.41%,respectively.Moreover,the activities of superoxide dismutase (SOD) and catalase (CAT) in Tagetes erecta leaves were significantly enhanced,while the contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were reduced by 10.66% and 12.26%.Peroxidase (POD) activity was significantly elevated after fulvic humic acid water soluble fertilize (FA) application.In summary,the present study indicated that foliar application of HA could effectively promote the growth of at the squaring stage of T.erecta,which could provide practical guidance for improving the field yield.
