摘要
在温室内以旱冬瓜幼苗为材料,探讨了4种不同磷浓度(磷质量浓度分别为25%、50%、100%、200%)处理下对旱冬瓜幼苗生长和氮磷吸收的影响。结果表明:不同浓度磷对旱冬瓜幼苗的生长产生不同的影响,且磷能明显促进地径的生长;不同磷浓度处理明显影响旱冬瓜幼苗生物量的累积和地上、地下生物量分配;不同供磷水平下旱冬瓜幼苗各器官氮磷养分含量不同。
Experiment on effect of different concentration （25%,50%,100%,200%）of phosphorus on growth and absorption of nitrogen and phosphorus of Alnus nepalensis seedling in greenhouse demonstrated that phosphorus could evidently promote growth of underground bole. Treatment of different concentrations of P had significant effects on biomass accumulation, aerial and underground biomass distribution. Different P supply level could effect N and P content in roots, shoots and leaves of seedlings.
