间作对油茶幼林生长及经济效益的影响

Effects of Intercropping on Growth and Economic Benefits of Camellia oleifera

为了探索出适合在霍山县油茶林中间种的植物,特开展了间作对油茶幼林生长及经济效益的影响研究。结果表明,间作植物类型的不同可在不同程度上影响造林成活率,其中间作花生可以显著提高油茶幼苗的成活率;各种间作处理均可对油茶幼苗的生长产生不同程度的影响;经济效益以间作黄菊、辣椒的处理较好,每年的净收益在2.4万元/hm^2以上。由此可知,在霍山县油茶林中,可以适当地间种辣椒、黄菊等,以弥补油茶造林后前几年经济效益低的问题。

In order to find out the suitable intercropping of Camellia oleifera in Huoshan County,the effects of intercropping on the growth and economic benefits of Camellia oleifera were studied.The results showed that different types of intercropping could affect the survival rate of afforestation in different degrees, intercropping with peanut could significantly improve the survival rate of seedlings of Camellia oleifera.Different treatment with intercropping could affect the growth of seedlings of Camellia oleifera in different degrees.The treatments of intercropping pepper and chrysanthemum had the better economic benefit, annual net income was more than 24 thousand yuan/hm^2.It can be concluded that pepper and chrysanthemum can be intercropped appropriately in the forest of Camellia oleifera in Huoshan County to compensate for the low economic benefits in the first few years after Camellia oleifera afforestation.
