柚子─—咖啡群落生态、经济效益的初步分析

Reckoning Ecological and Economical Benefits of Shaddock─—Coffee Community

根据柚子和小粒种咖啡的生理生态特点，构建柚子─—咖啡人工群落。此结构具改善栽培环境，促进咖啡生长，增强咖啡抗病虫害能力等良好的生态效益。单位面积上的经济收入比纯咖啡园有明显提高，减少了咖啡种植的经济风险，是滇南咖啡园中较优的组合栽培结构。

The shaddock（Citrits grandis Osb．）—coffee（Coffea arabica L.）community was con-structed on the basis of physiological requirements of shaddock and coffee. This interplanting structurehad better benefits of ecology such as stimulating coffee growth,ameliorating cultivation habitats andenhancing resistances of coffee to pests and diseases． The economical income in per unit area of shad-dock—coffee community was higher than that of pure coffee plantation，which could reduce the risk ofcoffee plantation. The shaddock—coffee model was better intercroping structure of coffee plantationsin southern Yunnan.
