Our study has shown that P. corylifolia absorbs and accumulates N2 and K2O most speedily in the periods of branching, flowering and fruiting, while P2O5 in the period of full flowering and fruiting. P2O5 is accumulated mainly in the seed and K2O in the stem. The nutriment accumulation is positively correlated with that of dry substances. To produce 100 kg of P. corylifolia an absorption of 10.59 kg of N2, 3.68 kg of P2O5 and 10.21 kg of K2O is needed.
我们的研究表明，巴戟天在分枝期、花期和果期对氮和氧化钾的吸收与积累最为迅速，而对五氧化二磷的吸收与积累则在盛花期和果期。五氧化二磷主要积累在种子中，氧化钾则积累在茎中。养分积累与干物质积累呈正相关。生产100千克巴戟天需要吸收10.59千克氮、3.68千克五氧化二磷和10.21千克氧化钾。
