Soil Properties of Different Planting Combinations of Zanthoxylum planispinum var. dintanensis Plantations and Their Effect on Stoichiometry

The soil quality of plantations with different planting patterns and the effect on stoichiometry provide a theoretical basis for selection Zanthoxylum planispinum var. dintanensis (hereafter Z. planispinum) nutrient management. Four mixed plantations: + Prunus salicina, Sophora tonkinensis, Arachis hypogaea, Lonicera japonica, monoculture plantation were selected to clarify stoichiometry. results showed that index (SQI) L. japonica (1.678) was highest, indicating it preferred combination significantly limited by water content (SWC). forms, SWC, pH all have significant effects processes such as transformation cycling. contributions total Ca Mg in nutrients relatively high, while SQI not significant. microbial ratio mainly influenced biomass phosphorus, reflecting microorganisms strong internal stability. Strong interactions among factors occur, affecting elemental geochemical processes. regulatory their should be emphasized.
