通过5年试验研究,筛选出5个较佳油茶立体结构模式,所有模式中与油茶混作的植物均生长良好,且能促进油茶增产。其中,以油茶+草珊瑚模式油茶增产和经济增值最大,茶油4年亩均年增产33.7％,收益亩均年增值307.5元。立体结构系统改变了生态环境,提高了油茶产量,取得了显著经济效益,节约了农业用地,提高了土地利用率,促进了区域资源的开发。 Through five years of experimental research, we screened five better three-dimensional structure patterns of Camellia oleifera. All the plants mixed with Camellia oleifera grew well, and the yield of Camellia oleifera increased. Among them, Camellia oleifera + grass coral model camellia increased production and economic value, the 4-year average annual output of tea oil increased 33.7%, average yield 307.5 yuan per mu. Three-dimensional structural system has changed the ecological environment, increased the yield of Camellia oleifera, achieved significant economic benefits, saved agricultural land, increased land utilization and promoted the development of regional resources.
