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 p...
