摘要
为更好利用和保护滩地生态系统,实现滩地区域生态安全与经济可持续发展。尝试将家禽养殖业和林业有机的结合起来,发展林禽复合产业。2006年在长垣县黄河滩地进行林鸡复合养殖,设置4个放养水平(每100m2林地投放5只(散养)、9只(散养)、13只(散养)、30只(舍养))。结果表明:林地内1年可养三季鸡,鸡子系统的加入使系统资金流动加快,循环周期及投资回收期缩短,可在短期内见效益,比单纯种植杨树见效快。采用林下放养的方式,鸡的体质好肉品优、价格较高、收益较多。因此,应加强农林复合系统中的次级生产以获得较高经济效益。4个放养水平鸡子系统的经济产投比分别1.69、1.62、1.21、0.15,可见放养密度与产投比呈负相关。林鸡复合经营模式,为滩地的保护、开发利用提供一个新的思路。
Forest-poultry compound management patterns were proposed to utilize and protect beach eco-system, keep ecological security and the sustainable development of the economy. Chick was cultivated in poplar stands in 2006 in beach of the Lower Yellow River, Changyuan County. Four levels was applied to raise chickens, including 5, 9, 13 and 30 chickens in the one hundred square meter, respectively. The results showed that 3 season chicken could be raised in woodland within 1 year, chicken subsystem joining the system sped up financial flows and shorten the cycle and investment recovery period. The economic efficiency of raising chicken in woodland was obtained more quickly than that of single poplar planting. Feeding chicken in woodland not only improved chicken physical and meat quality but also raised chicken price and economic returns. Therefore, secondary production in forestry ecosystem should be strengthened to gain higher economic efficiency. The ratio of outputs to inputs of four stocking level chicken subsystem was 1.69, 1.62, 1.21 and 0.15, respectively. The stocking density was negatively correlated with the ratio of outputs to inputs.
