摘　　要：为给油茶(Camellia oleifera)果实发育期间的管理和营养调控提供理论依据和实践指导,以岑软3号油茶为研究对象,探索其落果规律与叶片营养元素含量的变化。结果显示,岑软3号油茶3个落果阶段分别为1月上旬-3月上旬、4月上旬-5月下旬和8月上旬-10月上旬,落果率分别为12.99%、40.26%和14.29%;在对油茶林进行营养调控时,建议冬季休眠前的施肥应对本研究测定的全部营养元素进行不同程度的补充,夏季施肥应适当补充氮、磷、钾、铜、钙、锌和镁。In order to provide theoretical basis and practical guidance for management and nutrition regulation of fruit growth and development period of Camellia oleifera, Cenruan-3 C. oleifera was studied to explore regularity of fruit dropping and changes of leaf nutrient element contents. Results showed that three dropping stages of Cenruan-3 C. oleifera occurred from early January to early March, from early April to late May, and from early August to early October, respectively, and fruit dropping rates were 12.99%, 40.26% and 14.29%, respectively. It was suggested that all nutrient elements measured in this study should be supplemented with different degrees before winter dormancy, and nitrogen, phosphorus, potassium, copper, calcium, zinc and magnesium should be supplemented properly in summer in nutrition regulation of C. oleifera forest.
