竹林套种竹荪生态栽培技术研究与效益评价

试验研究了不同竹林郁闭度(郁闭度分别为0.6、0.7、0.8和0.9)、竹荪品种(长裙竹荪D89和D1)和竹林类型(散生竹和丛生竹)对林下竹荪生长及经济效益的影响。结果表明:竹林郁闭度对林下竹荪生长的影响极为显著,以郁闭度为0.7的竹林竹荪生长最好,出荪期达2个多月,产量达41.0 kg/667 m²,净利润为9 120元/667 m²;竹林套种不同品种的竹荪其产量和经济效益差异不明显;不同类型的竹林对于竹荪产量及经济效益的影响也不明显。因此,竹林适宜于套种竹荪,同时竹林套种竹荪还可带来减少环境污染、增加就业岗位以及促进竹林可持续经营等多重效益。

Cultivation Techniques and Benefit Evaluation of Bamboo Forest Intercropping with Bamboo Fungus

The impacts of bamboo forest crown closure (0.6, 0.7, 0.8 and 0.9, respectively), species of bamboo fungus (D89 and D1 of Dictyophora indusiata) and bamboo forest types (monopodial and sympodial) on the growth and economic benefits of understorey bamboo fungus. The results showed that the bamboo forest crown closure has very significant impact on the growth of understorey bamboo fungus. When the crown closure reaches 0.7, the understory bamboo fungus grow best with the fungus production period as long as 2 months and the production amount at 41.0 kg/667 m², and the net profit could amount to 9 120 yuan/667 m². There is no obvious variation between the production amount and economic benefits of different species of bamboo fungus intercropped with bamboo forest, and the bamboo forest of different types has no significant impact on the bamboo fungus production and economic benefits. Thus, it is economically beneficial to intercrop bamboo fungus in bamboo forest, which could also reduce the environment pollution, increase the employment and promote the the multiple benefits such as sustainable bamboo forest management.
