采用盆栽试验，比较研究四种不同供磷形态的磷源（K-P、Al-P、Ca-P、Fe-P）对油茶幼苗生长的影响。结果表明：K-P、Al-P和Ca-P处理均显著增加了油茶幼苗的苗高、地径和生物量；油茶幼苗的根系生长受磷源影响也较为显著，K-P、Ca-P和Al-P处理均显著增加了油茶主根生长，减小了侧根数和根冠比；不同磷源处理都显著增加了油茶幼苗磷含量，与对照相比，K-P、Ca-P、Al-P和Fe-P处理的叶片中磷增加量分别为99.00%、90.90%、84.16%和48.51%。结论：4种磷源对油茶幼苗生长的影响作用大小为K-P＞Ca-P＞Al-P＞Fe-P。%The pot-culture experiment was conducted to study the effects of 4 types phosphates (K-P, Al-P, Ca-P and Fe-P) on Camellia olerifera seedling. The results showed that K-P, Al-P and Ca-P significantly improved the height, ground diameter and biomass of Camellia olerifera seedling. The root growth of Camellia olerifera seedling was significantly influenced by phosphates. The K-P, Al-P and Ca-P significantly improved the main root length, reduced lateral root number and root/shoot ratio. Different types of phosphates significantly improved the phosphorus contents of Camellia olerifera seedling. Compared to CK, the increasing amount of K-P, Ca-P, Al-P and Fe-P in the leaves was 99.00%、90.90%、84.16%and 48.51%respectively. The experiment results suggested that the effects of 4 types of phosphates was K-P>Ca-P>Al-P>Fe-P.
