对不同发育期油茶林生物量与养分的生物循环进行了研究。结果表明，从幼龄期至盛果期油茶林生物量逐步积累，盛果期生物量达到１６．１３９ｔ／ｈｍ２，其中经济生物量为１．７９８ｔ／ｈｍ２；不同发育期油茶林分的生产力不同，盛果期油茶林太阳能利用率最高，为０．２％；不同发育期油茶林光合产物在各器官的分配比例不同；不同发育期油茶林系统大量元素（Ｎ、Ｐ、Ｋ、Ｃａ、Ｍｇ）的吸收量、存留量、归还量及输出量不同。并提出了油茶林系统施肥的监界量。
The bio-cycle of biomass and nutrients of Camellia oleifera in different developmental stages was studied. The results showed that the biomass of Camellia oleifera plantation accumulated from young to vigorous stage, the biomass reached 16.139t / hm2, and the economic biomass was 1.798t / hm2. The productivity of Camellia oleifera differed in different developmental stages , And the highest utilization rate of solar energy of Camellia oleifera forest in Shengguo period was 0.2%. The distribution proportion of photosynthetic products in Camellia oleifera Linn. Forest was different in different developmental stages. The contents of N, P, K, Ca, Mg ) Absorption, retention, return and output different. And put forward Camellia forest system fertilization monitoring volume.
