摘  要：
在盆栽控制条件下,测定了4个施肥处理下3个功能群组(豆科、禾本科和杂类草)9种草类植物成熟和衰老叶氮(N)和磷(P)浓度,以揭示不同功能群草类植物叶片氮、磷重吸收对施肥的响应。9种草类植物成熟叶N和P浓度(Ng和Pg)、衰老叶N和P浓度(Ns和Ps)、N和P重吸收效率(NRE和PRE)不同,对施肥的响应也不同。豆科草类Ng显著高于禾本科和杂类草,禾本科草类Ns显著低于豆科草类和杂类草,而杂类草NRE最低。杂类草Pg和Ps显著高于豆科和禾本科草类,而禾本科草类PRE最高。施肥对草类植物PRE影响不显著,对Ng、Pg、Ns、Ps和NRE影响显著,而在功能群水平,仅对Ng和Pg影响显著。施肥与物种的交互作用对叶片N、P重吸收有显著影响,与功能群的交互作用则无显著影响。

摘  要：
A pot experiment was conducted with 9 grasses which belong to three functional groups(legumes,graminoids and forbs)under four fertilization treatments to reveal the differences in leaf nutrient re sorption of these grasses and the responses to fertilization.Significant differences were measured in leaf N and P concentrations and re sorption among 9 grasses,and the responses to fertilization were different.The N concentration in green leaves of legumes was higher than those of graminoids and forbs,and N concentration in senesced leaves of graminoids was significantly lower than those of legumes and forbs,and N re-sorption efficiency of forbs was the lowest among 3 groups.Leaf P concentrations of forbs were significantly higher than those of legumes and graminoids,and P resorption efficiency of graminoids was the highest among all groups.There was no effect of fertilization on the leaf P re sorption efficiency of these grasses,while fertilization significantly affected leaf N and P concentrations,and N re sorption efficiency.At functional group level,it significantly affected N and P concentrations in green leaves.The interaction between fertilization and species had a significant effect on leaf N and P re sorption,while there was no interactive effect of fertilization with functional group on the characteristics.
