Background
With the increasing importance of China on ecological environment protection, the demand for technology for reconstructing a plant growth layer by peeling grass skin by using fresh peeled turf and being disturbed by different degrees is becoming stronger.
As the demand for recycling the stripped turf is increasing, in recent years, scholars propose to predict the change of the stacking vitality of the turf blocks according to the season of turf stripping and stacking, and to use geocells with side holes as framework supporting materials to slow down the vitality attenuation, tamp the slope during the back-laying, lay humus, base fertilizer and turf from bottom to top and correct the thickness to make the laid surface flush. The construction process of the scheme is complex; it has also been proposed by scholars to define turf protection levels based on natural vegetation types and coverage, and vegetation recoverable levels based on rainfall, temperature and soil factors, thereby defining a number of ecological control sections, and using different turf lifting and protection processes in different ecological control sections to maximize the protection of the stripped turf. As described above, the emphasis of the present research on the recycling of the stripped turf is mainly on the management of the stripped turf, so that the requirements of plant germination and growth can be met within a period of time after the stripping.

The resulting data were obtained from three replicates.
Fig. 2 and 3 are graphs showing the vegetation germination rate and seedling height of the example 1 peeling time 1d, respectively, of the turf restructured vegetation layer and the control group. As can be seen from fig. 2 and 3, the peeling time 1d, i.e. the turf restructured vegetation layer with smaller disturbance degree, has little change in vegetation germination rate and seedling height compared with the control group.
Fig. 4 and 5 are graphs showing the vegetation germination rate and seedling height of the example 2 peel time 90d, respectively, of the turf restructured vegetation layer and the control group. As can be seen from fig. 4 and 5, the peeling time 90d, i.e. the moderately disturbed turf restructured vegetation layer, showed little change in vegetation germination rate and seedling height compared with the control group.
Fig. 6 and 7 are graphs showing the vegetation germination rate and seedling height of the example 3 peeling time 180d, respectively, of the turf restructured vegetation layer and the control group. As can be seen from fig. 6 and 7, compared with the control, the peeling time 180d, i.e. the turf restructuring vegetation layer with a large disturbance degree, has better vegetation germination rate and seedling height than the control group, wherein the turf restructuring vegetation layer added with 10% concentration of the modified organic material has the best effect of improving vegetation germination rate and seedling height.
Fig. 8 and 9 are graphs showing the vegetation germination rate and seedling height of the example 4 peel time 210d, respectively, of the turf restructured vegetation layer and the control group. As can be seen from fig. 8 and 9, the peeling time 210d is that the turf reconstruction plant growth layer is completely disturbed, and compared with the control, the vegetation germination rate and the seedling height of the turf reconstruction plant growth layer are better than those of the control group, wherein the turf reconstruction plant growth layer added with 10% concentration of the modified organic material has the best effect of improving the vegetation germination rate and the seedling height.
FIG. 10 is a graph comparing the above-ground biomass after the re-paving of the turf restructured vegetation layer with the control group for 30d at different peeling times of examples 1-4. As can be seen from fig. 10, compared with the control, the 30d aboveground biomass of the turf reconstructed plant layer with longer peeling time (more than 180 d), namely the disturbed degree, is better than that of the control group, wherein the turf reconstructed plant layer added with the 10% concentration modified organic material has the best effect of improving the 30d aboveground biomass; whereas for turf with shorter peel times (< 90 d), i.e. less disturbed, the 30d aboveground biomass of the turf restructured vegetation layer did not change much compared to the control.
FIG. 11 is a graph comparing chlorophyll content of vegetation after the re-growth of the turf with the control group at different peeling times for 30 d. As can be seen from fig. 11, compared with the control, the 30d chlorophyll content of the turf reconstructed plant growth layer of the turf with longer peeling time (more than 180 d), namely the turf with large disturbance degree, is better than that of the control group, wherein the turf reconstructed plant growth layer added with 10% concentration of modified organic material has the best effect of improving the 30d chlorophyll content; whereas for turf with shorter peel times (< 90 d), i.e. less disturbed, the 30d chlorophyll content of the turf restructured vegetation layer did not change much compared to the control.
FIG. 12 is a graph showing the comparison of soil moisture content after 30d of the re-established vegetation layer with the control and before the control at different peeling times. As can be seen from fig. 12, the soil moisture content can be effectively improved by improving the turf restructured vegetation layer using the modified organic material, wherein the turf restructured vegetation layer added with the 10% concentration modified organic material has the best effect of improving the soil moisture content.
FIG. 13 is a graph comparing soil pH after 30d of the re-emergence of the grass with the control and before the control. As can be seen from fig. 13, by using the modified organic material to modify the turf restructuring layer, the pH of the soil can be reduced, and the acidity of the soil can be slightly raised, so that the pH of the soil is more suitable for germination and growth of vegetation.
