费菜林下套种生态栽培技术

Ecological Cultivation Technologies of Relay Cropping Phedimus aizoon Under Forestry

为了提高果园林下空地利用率,发展林下经济,经过2年水蜜桃—费菜林下栽培试验,总结了在桃林下套种费菜的生态栽培技术,主要内容包括果园选择、费菜种苗繁育、套种、定植、田间管理及采收等。套种模式下,明显改善了费菜的口感品质,比常规栽培增产10%~20%,费菜667 m^(2)产量5000~6000 kg,水蜜桃667 m^(2)产量1500~1750 kg,实现667 m^(2)经济效益近5万元;同时,可以减少果园杂草、病害和水蜜桃生理性裂果的发生。费菜林下套种生态栽培技术模式结合了水蜜桃特色产业发展优势,实现了良好的优势互补,生态经济效益明显,适合我国南方山区作为林下经济发展模式借鉴推广应用。

In order to improve the utilization rate of open space and develop the under-forestry economy,the ecological cultivation technology of Phedimus aizoon under-forestry was summarized through two years of cultivation tests for Phedimus aizoon under-forestry relay intercropping Amygdalus persica,which included orchard selection,breeding of vegetable seedling,relay intercropping,planting,field management,harvesting and so on.The relay intercropping mode could obviously improve the taste quality of Phedimus aizoon,increase the yield of 10%-20%than conventional cultivation.Phedimus aizoon had a yield of 5000-6000 kg per 667 m^(2),and Amygdalus persica had a yield of 1500-1750 kg per 667 m^(2),achieving an economic benefit of nearly 50000 yuan per 667 m^(2).At the same time,it reduced the weeds,diseases and occurrence of physiological fruit cracking in Amygdalus persica in the orchard.The ecological cultivation technology mode of Phedimus aizoon under-forestry relay intercropping combined with the local peach industry,had realized a good complement of advantages and obvious ecological and economic benefits,which was suitable for the southern mountainous area of China as a mode of economic development under forest.
