Comprehensive Evaluation of Substrate Selection for Container Seedling Cultivation of Three Xerophytic Tree Species Based on the Entropy Weight Method

Pengfei Shi, Qiangfeng Li*, Linlin Li

Abstract

To optimize substrates for container cultivation of xerophytic trees, Haloxylon ammodendron, Tamarix chinensis, and Atraphaxis
bracteata were tested using an L9(34
) orthogonal design with nine mixtures of native soil, organic fertilizer, landscape waste, and vermiculite.
Substrate properties and seedling growth were signifi cantly affected. Bulk density ranged from 1.4-1.72g/cm-
; porosity from 48.61%-59.27%.
T7 and T8 showed superior overall performance. T8 promoted chlorophyll in H. ammodendron (1.21mgg-
) and biomass in T. chinensis; T6
favored A. bracteata. Entropy weight analysis identifi ed T3, T7, and T6 as optimal for the three species. Results support substrate selection
and landscape waste reuse in arid-region nurseries.
