摘要

The resuhs present differences in the succession and structure of permanent grassland (PG), newly sown grass stand (conversion of arable land to a set-aside), and two variants of spontaneous grassing (with and without Glyphosate herbicide) after theirmulching three times and one time a year. Mulching 3 times a year is connected with the lower accumulation of dead phytomass (11.8% of the total phytomass). This intensity of mulching also exhibits significant differences in sward variants, with the exception of spontaneously grassed stands. The share of the grass component is entirely dominant in permanent grassland (> 90%). In the sown variant of clover grasses, the dominant Lolium sp. and Poa pratensis suppress the dominance of Elytrigia repens considerably to 10.8% (3 X mulch) and 21.7% (1 X mulch). Spontaneously grassed stands show a visible succession phase of dominance of Elytrigia repens, with the species' cover being 50-70%. Mulching once a year reduces the number of species, particularly inthe group of forbs. In comparison with newly established grass stands (15-21 species), permanent grassland shows a lower number (9-12).
