国外泥炭藓种植业的研究进展

Progress in Sphagnum Farming Research in Western Countries

泥炭藓作为一种优良的栽培基质原材料,由于其市场需求量大,应用前景广阔,已得到许多国家的认可。为了满足不断增长的市场需求,最大限度地减少开采泥炭藓给环境带来的负面影响,欧洲和北美相继开展了在泥炭开采迹地种植泥炭藓的实验研究。研究结果表明,在泥炭开采迹地种植泥炭藓,既可以恢复泥炭地、增加对大气碳的固定,又能够满足市场对栽培基质的需求,具有较强的环境价值和经济技术可行性。本文介绍了欧洲的德国、丹麦和北美的加拿大泥炭藓种植的方法和近期研究进展,以期为我国泥炭地恢复重建和泥炭藓种植研究提供借鉴。

Sphagnum is a kind of raw materials of fine culture substances. The market demand is large and the application has a promising future, it has already been approved by a lot of countries. In order to fill the demand of the market which is increasing constantly and reduce the negative effect brought to environment by exploitation of Sphagnum to the maximum extent, Europe and North America launched experiments in planting Sphagnum at peat exploiting slashes in succession. The results indicated that planting Sphagnum at peat exploiting slashes can both restore the peatland, increase the proportion of fixed carbon in the air and meet market＇s demands for culture substrates. It has great environment value and economical and technical feasibility. This paper introduces the method of planting Sphagnum and the latest advances in Germany, Danmark and Canada, which is expected to provide reference for restoration and reconstruction of peatlands and the studies of Sphagnum planting.
