“九五”国家科技攻关项目——湘北红壤低丘岗地农业综合发展研究专题试验区——湖南省桃源县盘塘镇,在当地党委、政府的精心组织和专家的指导下,大力发展生态农业,推出五种生态农业模式,使农业生产走向良性循环的轨道。——“围山转”的立体生态农业模式。山顶栽松,山腰栽油茶,山脚栽果树,实现用材林、经济林优势互补,共同发展。1991年以来全镇开发丘岗地2.2万亩,山顶裁湿地松3000亩,山腰植油茶、板栗3000亩,山脚种柑桔1.6万亩。各林带幼树培植期,实行林粮(黄豆、红薯)、林油(花生)间作,既能熟化土壤,保持水土,又可以 National Science and Technology Research Project of the Ninth Five-Year Plan - Special Experimental Zone for Comprehensive Agricultural Development in Low Hilly Areas of Red Soil in North Hunan - Pan Tang Town, Taoyuan County, Hunan Province Under the guidance of well-organized local party committees and governments and experts, the ecological agriculture , Launched five kinds of ecological agriculture model, so that agricultural production into a virtuous circle of orbit. - “Wai turn” three-dimensional ecological agriculture model. Pinus sylvestris, hillside planting tea, planting fruit trees at the foot of timber forest, economic forest complement each other and common development. Since 1991, 22,000 mu of hillock land has been developed in the town, and 3,000 mu of topsoe pine has been delineated at the top of the hill. There are 3,000 mu of hillside tea plants, 3,000 mu of chestnut and 16,000 mu of mountain and mountain citrus. Saplings of young trees in the cultivation period, the implementation of forest grain (soybeans, sweet potatoes), Lin oil (peanut) intercropping, both soil maturity, to maintain soil and water, but also
