黄腐酸螯合锌、铁叶面肥的制备及其施肥效果研究
Study on preparation and fertilization effect of fulvic acid chelate zinc and iron foliar fertilizer
摘要
Abstract
Using biochemical humic acid(BFA)as raw material,humic acid leaf fertilizer(AB-FA)was prepared by ultrasonic activation method.ABFA was used as a chelating agent,Fe-SO4 as an iron source,and ZnSO4 as a zinc source to prepare humic acid chelated iron leaf fer-tilizer(ABFA-Fe)and humic acid chelated zinc leaf fertilizer(ABFA-Zn).On the basis of single factor experiments,the optimal preparation conditions for ABFA-Fe and ABFA-Zn were optimized using orthogonal experiments with chelation rate as the indicator.The struc-ture and morphology of three types of foliar fertilizers were characterized by UV-Vis,FT-IR,XPS,XRD,and SEM.The results showed that the optimal preparation conditions for ABFA-Fe were pH=5,reaction temperature 50 ℃,m(ABFA)∶m(FeSO4)=1∶2,reaction time 60 minutes,and chelation rate 59.93％;The optimal preparation conditions for ABFA-Zn were:pH=7,reaction temperature 30 ℃,m(ABFA)∶m(ZnSO4)=1∶2,reaction time 120 mi-nutes,and chelation rate 85.93％.The planting experiment results showed that ABFA-Fe and ABFA-Zn can effectively increase the chlorophyll content of leaves and promote the growth of small rapeseed.关键词
