本文对杨树+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。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的第一年年产值达62 530元、净收益达到29 438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27 000元、净收益为22 900元,是单纯栽培杨树速生丰产林的13.7倍。
In this paper, poplar + mushrooms and poplar + Agaricus bisporus two kinds of composite business model were studied. Through the investigation and analysis, it is found that the two composite management modes significantly increase the DBH, tree height and volume growth of trees, reduce the cost of forest tending and management, and have high economic benefits. Poplar + mushroom composite model into a larger, 8-year-old stand volume annual growth volume increased by 22.9%, 666.7m2 each of the first annual output value of 62 530 yuan, the net income reached 29 438 yuan, compared with simple cultivation Yang Tree quick-growing forest net income as much as 14 times. Poplar + Agaricus bisporus compound management mode investment is small, 6-year-old stand volume annual growth rate increased 47.8%, 666.7m2 annual output value of 27 000 yuan, net income of 22 900 yuan, is a simple cultivation of poplar fast-growing 13.7 times of high yield forest.
