北京沟域典型农林复合经营经济效益分析

Typical Agroforestry Complex Management Technology and Its Economic Benefits in Beijing Vally Areas

分别在京郊房山蒲洼沟域、怀柔栗花沟沟域,采用林下复合栽培试验及林下复合养殖试验,进行了＂林菌＂、＂林禽＂两种典型农林复合经营技术的研发,形成京郊沟域农林复合经营技术体系,并分别进行了效益对比分析,对北京沟域经济及类似山区生态经济发展具有借鉴和指导意义。研究结果表明,高山林下栽培毛木耳、香菇的适宜品种分别为毛木耳781、香菇L808,林菌复合经营的效益产出为16.5万～22.5万元/hm2;盛果期每1hm2果园养殖2490只家禽较为适宜,林禽复合经营的的效益产出平均为22.5万元/hm2,增收效益明显。

This paper made trials of culturing different mushrooms and poultries under different kinds trees in Beijing northern mountain area and western mountains area respectively. So formed ＇forestry- mushroom＇ and ＇forest- ry -poultry＇ agroforestry management technological system. At the same time, their economical benefits are analysed. Results showed that the adapted mushroom seeds for ecological forests in high high mountains are Auricularia polytri- cha 781 and Lentinula edodes L808, of which benefit is 11000 - 15000 ￥/667m2; The adapted Breeding density is 166 poultry per 667 m2 orchard for full bearing period, of which benefit is 15000 ￥/667m2. Benefit for agroforestry complex management is obvious.
