植酸基生物源磷复肥的制备与表征
Bio-Derived Phosphate Compound Fertilizer for Sustainable Agriculture
摘要
Abstract
Nitrogen,phosphorus,and potassium are three essential nutrients for crop growth.Phosphorus primarily originates from phosphate rock,however,high-grade phosphate resources are at risk of depletion due to their uneven distribution and growing demand.Moreover,low-grade phosphate ores often contain harmful impurities,making their processing expensive.Consequently,it is necessary to explore alternative phosphorus sources and develop phosphorus recycling.Phytic acid,a biologically derived organic phosphorus compound,exhibits a phosphorus content(P₂O₅ mass fraction>60%)higher than that of high-grade phosphate ores.This study investigates the physicochemical properties of phosphate fertilizer solution derived from phytic acid and their effects on crop growth.Through nuclear magnetic resonance spectroscopy(NMR)and matrix-assisted lasear desorption/inoization time of flight(MALDI-TOF-MS)analysis,it was found that although phytic acid from different sources showed significant variations in chemical composition,primarily in the degree of inositol phosphate ester substitution,the resulting fertilizer complexes obtained through acid-base reactions exhibited similar structures,providing a basis for the large-scale utilization of industrial-sourced phytic acid.Pot experiments indicate that phytic acid-based phosphate fertilizer solution(PA from Shanghai Aladdin Biochemical Technology Co.,Ltd.and PC from Guangzhou Fufei Chemical Technology Co.,Ltd.)are more favorable for the initial growth of maize seedlings compared to blank controls.These fertilizers also enhance the hundred-grain weight,kernel number per spike,and total phosphorus content in wheat,contributing positively to phosphorus recycling efforts.关键词
