| description | [Objective] Under the condition of ensuring the quality of the grass blanket, the study aims to
select the appropriate combination of substrate thickness and seeding rate, and achieve the coordination
and unity of ecological and economic effects in grass blanket production. [Methods] Using Poa pratensis as
the grass species, 12 indoor potted treatments were established, combining 3 sowing rates (15, 30, and 45
g/m2) with 4 substrate thicknesses (3, 5, 7, and 9 cm). This was done to examine the characteristics of
sandy ecological grass blankets under varying conditions of sowing rates and substrate thicknesses, and to
holistically assess the quality of the blanket formation. [Results] The results revealed significant variations
in the quality indicators of the P . pratensis grass-based ecological blankets across different treatments.
Z9/45 treatment (substrate thickness of 9 cm and sowing rate of 45 g/m2) yielded the highest plant density,
aboveground biomass, and root biomass. Z3/15 treatment had the highest chlorophyll content, while Z7/45
treatment had the highest root tensile strength and vitality. Z5/45 treatment had the highest root length
density, while Z9/15 treatment had the smallest leaf width and the best texture. Z9/45 treatment received the
highest comprehensive score for blanket formation traits, as assessed by both variation analysis and membership
function methods. [Conclusion] Z9/45 treatment of the grass blanket not only demonstrated excellent
plant density, aboveground biomass, and root biomass but also exhibited superior overall performance.
The optimal combination for preparing the P . pratensis grass blanket with sand-based ecology was a
substrate thickness of 9 cm and a sowing rate of 45 g/m2. |
