研究采用盆栽试验,对油茶幼苗施用五种处理,分别是不施磷源的对照和施用K-P(KH2PO4)、AL-P(AlPO4)、Ca-P(Ca3(PO4)2)、Fe-P(FePO424H2O)等四种磷源.研究了不同磷源对油茶幼苗苗高、地径、主根长、侧根数、生物量、根冠比和根茎叶中氮磷钾含量的影响,结果表明:(1)K-P(KH2PO4)、AL-P(AlPO4)和Ca-P(Ca3(PO4)2)可以明显增加油茶幼苗的苗高、地径、生物量和主根长,减小侧根数和根冠比,而Fe-P(FePO424H2O作用不显著.(2)不同磷源处理都明显增加了油茶幼苗磷含量,K-P、Ca-P、AL-P和Fe-P处理的增加量分别为99.00％、90.90％、84.16％和48.51％.

　　The pot experiment was conducted to investigate the effects of 4 kinds of phosphorus sources (K-P,AL-P,Ca-P and Fe-P) on Camellia olerifera seedling.Studied the effects of different phosphorus sources on the seedling height,ground diameter,main root length,lateral root number,biomass,root/shoot ratio and the contents of NPK.The results were following:1) The K-P,AL-P and Ca-P significantly improved the seedling height,ground diameter,main root length,biomass of Camellia olerifera seedling,but obviously reduced lateral root number and root/sh...
