Abstract:

The kinetic characters of Mn Nutrition stress caused by continuous cropping soybean were investigated by pot experiment,field experiments and chemical analysis.The results indicated that the contents of available Mn in soil of soybean continuous cropping is totally higher but the uptake and accumulation of Mn in soybean plant is lower than that of rotation in different soybean continuous cropping years and different growth stages,the variation is especially significant at full blooming-podding-seed filling vegetative stage.Mn nutrition of plant was highly significantly correlated with nitrogen and phosphorus nutrition of plant at different growth stages.Mn nutrition of plant was correlated significantly with polyphenol oxidase activity at branching stage,Mn nutrition of plant was correlated significantly with yield at full flowering and podding stage.Furthermore the reasons for available Mn changing in soil were also discussed.The scientific grounds for reasonable regulating Mn changing in soil were also discussed.The scientific grounds for reasonable regulating Mn nutrition of soybean continuous cropping and alleviating continuous cropping barriers are recommended by the study.
