皖南山区香榧生态种养技术

Ecological Planting and Breeding Technology of Torreya grandis‘Merrilli’in the Mountainous Area of Southern Anhui Province

香榧产业是皖南山区实现增收致富和乡村振兴的重要途径之一,然而当地栽植户缺乏对香榧生态栽植管护的理论知识,引起土壤酸化、病虫害频发、水土流失等生态问题,不利于山区木本油料产业可持续发展。文中阐述了酸化土壤修复、茶枯饼浸提液防治虫害等香榧生态种植技术,介绍了复合经营模式下不同养殖密度对土壤理化性质和香榧生长的影响,并对比了不同种植模式的经济效益,总结出适宜山区推广的香榧生态化种植与林下种养关键技术,为产业健康发展提供技术支撑。

Torreya grandis‘Merrilli’industry is one of the important ways to achieve income increase and rural revitalization in the mountainous area of southern Anhui province,but the local growers lack theoretical knowledge of ecological planting and management of T.grandis‘Merrilli’,causing ecological problems such as soil acidification,frequent pests and diseases,soil erosion,etc.,which is not conducive to the sustainable development of the woody oilseed industry in mountainous areas.The ecological planting technology of T.grandis‘Merrilli’was elaborated,the impact of different breeding densities on soil physical and chemical properties and growth of T.grandis‘Merrilli’under the composite management mode was introduced,the economic benefits under different planting modes were compared,and the key technologies suitable for promoting ecological planting and understory planting and breeding of T.grandis‘Merrilli’in mountainous area were summarized to provide technical support for the healthy development of the industry.
