油茶是茶科茶属的常绿小乔木,是我国主要的油料树种,具有东方橄榄油的美称,广南县曾是云南省油茶的主产区。长期以来,由于种植农户缺乏科学管理技术,投入跟不上,管理粗放,以及品种混杂、老化,栽植密度普遍过大、林相衰败,产量低且不稳定等原因,油茶没有为山区群众带来良好的经济效益。笔者通过实地调查,总结出适应于广南县的油茶低产林改造技术措施,现阐述如下。
Camellia is an evergreen small tree of Teaaceae and is the main oilseed species in our country. It has the reputation of oriental olive oil. Guangnan County was once the main producing area of Yunnan camellia. For a long time, Camellia did not bring good results to the mountainous masses due to the lack of scientific management techniques, lack of input, lack of management, extensive management, miscellaneous varieties, aging, widespread planting density, declining forest phase, low yield and instability The economic benefits. Through field investigation, the author concluded that the technical measures for transformation of Camellia low-yielding forests adapted to Guangnan County are as follows.
