| 摘 要： | 檫树根际土壤的金磷、有机磷和有效磷含量明显高于杉木根际土。两种林木根际土的元机磷总量无显著差异，但无机磷的组成有很大不同，表现在杉木根际土闭蓄态磷比例很高（占无机磷的组成有很大不同，表现在杉木根际土闭蓄态磷比例委高（占无机磷的６１．４８％），而檫树根际土明显低（仅占３９．６９％）。檫树根际土Ｆｅ－Ｐ，Ｃａ－Ｐ的含量显著高于杉木奶际土。杉木、檫树根际土中的有效磷都和ＡＬ－Ｐ，Ｃａ－Ｐ显著相关，ＡＬ－

| Abstract: | There is higher content of total-P,organic-P and availabe-Pinthe rhizosphere soil of Chinese sassafras than that of Chinese fir.Betweenthe rhizosphere soils of the two kinds trees,there is no significant differencein mount of mineral phosphorus but is significant difference in its constitu-ent,which can be explained by much more content of occluded-P(acountedto 61.48%of mineral phosphorus)in Chinese fir rhizosphere soil than that(acounted to 39. 69%)in Chinese sassafras,and by much more content of Fe-Pand Ca-P in Chinese sassafas rhizosphere soil than that in Chinese fir.Intwo rhizosphere soils, the quantity of available-P is largely correlatedwith contents of Al-P and Ca-P,while there is lower content of Al-P. |
