毛竹林空间立体经营研究

研究目的在于利用毛竹林蔽荫、风小、湿润的独特环境条件,以及拥有较多的竹枝、竹叶、竹箨等凋落物和残留在地里的死竹篼、死竹鞭等有机物,进行地下栽培棘托竹荪和利用空间挂袋毛木耳的立体经营研究。研究结果表明,这一模式切实可行,既提供了人们物质生活所需的竹荪、毛木耳产品,又改善竹林环境条件,提高笋、竹产量和质量。获得菇、竹双丰收。栽培竹荪,起到垦复竹山,抚育松土和施肥培土的作用;同时,竹荪、毛木耳呼吸作用所释放大量的CO2,大大增加竹林干物质积累,为竹林高产稳产奠定了基础。产值可达13514元·hm-2,比单纯经营竹林翻3番多,经济、生态效益显著。

The Study on Stereoscopic Management of Phyllostachys pubescens Forest

Taking the advantage of special environment of Phyllostachys pubescens Forest,which was shadowy,weak wind,wetness,rich litter as well as rich dead bamboo pockets and roots,the stereoscopic management technique that Dictyophora echinovolvata was cultivated on the ground and Auricularia polytricha was raised with bags suspended in the forest was develope.The results were as follows:The stereoscopic management technique was simple and practice.It not only produced the products of Dictyophora echinovolvata and Auricularia polytricha,improved the environment of bamboo forest,but also increased the output and quality of bamboo and shoot.The bamboo forest land could be reclaimed,softened,and fertilized by cultivating Dictyophora echinovolvata,at the same time,Dictyophora echinovolvata and Auricularia polytricha could release a large amount of CO2,which was benefit for biomass accumulation and high production of bamboo forest.The production value was up to 13 514 RMB/hm~(-2),which was as 3 times as that of pure bamboo forest.Therefore,stereoscopic management had obvious economic and ecological benefit.
