油茶林下药用黄菊种植技术与效益分析

Cultivation technology and benefit analysis of planting medicinal yellow chrysanthemum under Camellia oleifera forest

油茶为南方重要的经济林树种,但种植前期投入高,产出的经济效益低等问题限制了油茶产业的发展。本研究通过对比试验,分析油茶林下种植药用黄菊带来的生态效益和经济效益。结果表明:较油茶纯林而言,林下种植黄菊后,提高了林地土壤肥力,油茶树体生长指标均得到提升,抽梢数量增加25.32%,平均梢长度增加24.03%,树高、地径、冠幅的生长量分别增加14.28%、32.18%、27.78%。同时,林下种植黄菊能带来良好经济效益,有利于解决油茶在进入盛果期前收益低的问题,实现油茶种植以短养长的目的,建议在江西、湖南等油茶产区大面积推广。

Camellia oleifera is a important economic forest tree species for the south China,but the high costs in the early stage of the plant and the low economic benefits of output limits the development of camellia industry.Through contrast experiment,this study analysis of camellia forests ecological benefits and economic benefits of planting medicinal yellow chrysanthemum.Results showed that:Contrast with the C.oleifera pure forest,planting yellow chrysanthemum in the forest can improve the woodland soil fertility,the growth indexes of C.oleifera were promoted.Smoke tip number increased by 25.32%,average tip length increased by 24.03%,the tree height,diameter and crown increased by 14.28%,32.18% and 27.78%.At the same time,planting yellow chrysanthemum under the forest can bring economic benefits,which is conducive to solving the problem of low profit before C.oleifera enters the fruiting period,and realizing the purpose of planting C.oleifera for short growth.It is suggested to popularize in Jiangxi,Hunan and other C.oleifera producing areas.
