油茶幼林不同套种模式与综合效益分析

An integrated benefit evaluation different interplant models for young tea-oil plantation

为进一步提高油茶林经营的综合效益,对油茶幼林不同套种模式进行了3年对比试验,对油茶苗定植成活率,幼苗地径、树高、分枝和冠幅的生长量,以及各年度的经济效益进行了综合分析和评价。结果表明:油茶-花生为最佳套种模式,其次是油茶-花生、西瓜、花生轮作套种模式,再次是油茶-黄豆和油茶-紫薯套种模式,这几种套种模式可以因地制宜的推广。

In order to further improve the integrated benefit of young tea-oil forests, we investigated the survival rate and in- crements （ground diameter, height, branch number, crown diameter） in young plantation of tea oil（ Camellia oleifera） with different crops for 3 years, and evaluated comprehensive benefits of every models. The result showed that interplant with tea oil-peanut was the best, followed by crop rotation with tea oil-peanut, watermelon, peanut, the third was tea oil- soybean, the forth was tea oil-purple potato. These interplant models could be expanded basing on local conditions.
