摘　　要：2008～2009年在吉林省公主岭黑土上研究有机肥磷部分替代化肥磷对春玉米干物质积累、产量、养分吸收和利用的影响。结果表明,有机肥磷替代化肥磷增加苗期或拔节期土壤速效磷含量;与100%化肥磷处理相比,用30%有机肥磷替代化肥磷对玉米干物质积累、子粒产量和磷素吸收没有显著影响,但显著增加营养体磷素的再分配率和对子粒的贡献率,提高了磷素的农学效率。In 2008 and 2009,field trials were conducted in spring maize in black soil of Jinlin to evaluate the effects of phosphorus（P） substitution by manure P on biomass,grain yield and P use efficiency.The results indicated that soil Olsen-P increased in seedling or jointing stage by manure substitutions.Compared with full chemical P,manure substitutions for P did not significant influence on biomass accumulation,grain yield and P uptake.Manure substitutions for P significantly increased P redistribution and contribution efficiency from vegetative parts to grain.Agronomic efficiency was also increased by manure substitution.
