摘 要:对杨树+香菇和杨树+双孢菇两种复合经营模式进行了试验研究。通过调查和分析发现,该两种复合经营模式显著提高了林木的胸径、树高和材积生长量,降低了林木抚育管理成本,具有较高的经济效益,是一种高效栽培模式。杨树+香菇复合模式投入较大,8林龄林分材积年均生长量增加了22.9%,每666.7m2的第1年年产值达62530元、净收益达到29438元,较单纯栽培杨树速生丰产林的净收益多达14倍。杨树+双孢菇复合经营模式投入较小,6龄林林分材积年均生长量增加了47.8%,每666.7m2年总产值达27000元、净收益为22900元,是单纯栽培杨树速生丰产林的13.7倍。Compound pattern of poplar+mushroom and poplar+agaricus bisporus was studied. The results show that the growth of poplar is significantly increased, the cost of tending and manage is decreased, the economic benefits is higher in the forestland of two compound pattern; in the compound pattern of poplar+mushroom, the annual growth increment of poplar volume of 8 stand ages is increased by 22.9%, the production value is 62530 yuan and net income is 29438 yuan for per 666.7 m2 in first year, the net income 14 times than the poplar pure stand; in the compound pattern of poplar-Agaricus Bisporus, the annual growth increment of poplar volume of 6 stand ages is increased by 47.8%, the production value is 27000 yuan and net income is 22900 yuan for per 666.7 m2 , the net income 13. ? times than the poplar pure stand.
