.本文描述了人工植物覆盖对泥炭收获后裸露泥炭表面植物定殖的影响。植物物种殖民地进行了比较，提供了塑料模型模拟越桔，idaea植物和地块没有这种人工覆盖。经过两个生长季节，物种组成和总生物量的建立植物覆盖是相似的两个样地类型。但人工覆盖样地的成苗数显著高于无覆盖样地。
在13个物种观察到四个显着不同的表现在两个情节类型。白桦在试验地上具有较高的幼苗数量和较高的生物量;丛生发草具有较高的生物量，但幼苗太多而无法计数;垂柳具有较高的幼苗数量。而人工覆盖样地的柳叶菜幼苗数则较低。
因此，白桦、D. cespitosa和S.人工植被下改善的小气候和土壤水分条件是促进phylicifolia生长的主要因素。另一方面，E.狭叶草可能受到试验地块上增加的阴影的负面影响。
. This paper describes the effect of artificial plant cover on plant colonization of a bare peat surface, resulting from peat harvesting. Plant species colonization was compared on plots supplied with plastic models simulating Vaccinium vitis-idaea plants and plots without this artificial cover. After two growing seasons, species composition and total biomass of the established plant cover were similar in the two plot types. However, the number of established seedlings in the plots with artificial cover was significantly higher than that in the plots without cover.
Out of 13 species observed four differed significantly in their performance on the two plot types. Betula spec. had both higher seedling numbers and higher biomass on the test plots; Deschampsia cespitosa had a higher biomass, whereas the seedlings were too numerous to be counted; Salix phylicifolia had higher seedling numbers. On the contrary, the number of seedlings of Epilobium angustifoliwn was lower on plots with artificial cover.
It is suggested that colonization by Betula, D. cespitosa and S. phylicifolia was facilitated mainly by the improved microclimatic and soil moisture conditions under the artificial plant cover. On the other hand, germination of E. angustifolium may be negatively influenced by the increased shade on the test plots.
