摘要
将鸡、猪、沼、菜等生物组分整合成一个生态微循环系统,形成陕北四位一体庭院生态模式,研究分析了该模式结构、模式示范及其配套技术体系建设和效益。与普通温室、普通圈养比较,该模式可使果菜类蔬菜增产16％～20％,生产成本减少1.17～1.56万元/hm^2,增加收入5.47～5.8万元/hm^2;可使猪生长加快,日均增重达700g,出栏期缩短30多d,饲喂成本减少150～170元/头,为在黄土高原丘陵区进一步广泛推广应用该模式提供了科学依据。
A four-in-one courtyard ecological pattern has been established in Northern Shaanxi, being an ecologically micro-circled system composed of cheken, hog,biogas and vegetable. The structure,benefit and demonstration of the pattern as well as the construction of necessary techni-cal system were expounded. The pattern's economic benefit compared to common greenhouse and sty-feeding was analyzed. The result showed that the pattern increased vegetable production by 16%-20% ,decreased production cost by 11700-15600 yuan/hm2 and raised income by 54700-58000 yuan/hm2; hogs grew quickly, growth rate reached 700g a day on average, feeding period was shortened by one month,feeding cost decreased by 150-170 yuan per hog,and income raised by 81-108 yuan. The research provided a scientific basis for extensive use of this pattern in the hilly and gullied areas of Loess Plateau.
