不同林地管理方式对油茶林的影响

为了提高油茶的种植经营水平，研究修剪、林下养鸡、对照(CK)3种林地管理方式对油茶林的影响。结果表明，油茶幼林林下养鸡使油茶坐果率显著降低，坐果率比对照减少了9.1%，从而使产量大幅度降低；油茶林下养鸡能使林地土壤肥力提高，土壤有效氮含量、有效P和有效K分别比对照提高了33.3、8.9、0.5 mg/kg；修剪能使油茶当年坐果率降低，比对照减少了4.5%，但保果率却大幅度提高，比对照增加了28.1%，产量比对照增加了0.28 kg/株。

The Impact of Different Forest Land Management Practices on Camellia oleifera

In order to improve planting operations level of Camellia oleifera, the impact of 3 forest land managements including pruning, breeding chickens, control on oil-tea Camellia forest was studied. The results showed that fruit set percentage significantly reduced in breeding chickens under oil-tea Camellia forest, which decreased 9.1% compared with the control （CK）, and the yield also significantly reduced. But improving soil fertility, soil available N, available P and available K were increased by the 33.3 mg/kg, 8.9 mg/kg, 0.5 mg/kg, respectively. Fruit set percentage significantly reduced induced by pruning, a decrease of 4.5% compared with the control, but the fruit retention rate improved greatly, an increase of 28.1% compared with the control, the yield was increased by 0.28 kg/plant.
