Fertilization can improve soil nutrition and increase the yield of Sapindus mukorossi, but response microbial communities to fertilization treatments their correlation with mukorossi are unclear. In order investigate characteristics physicochemical qualities bacterial community, we carried out a field experiment comparing various quantities nitrogen (N), phosphorus (P), potassium (K) fertilizers unfertilized control in raw material forests different applications try clarify interrelation among three. Results showed that (1) there significant differences effects on properties forests. The application rates or significantly reduced pH value. (2) Compared control, α-diversity was lower N3P2K2 N1P1K2 treatments. Among dominant groups bacteria at phylum level, relative abundance Chloroflexi an then decrease trend N application. Firmicutes, Bacteroidota, Fusobacteriota positively correlated P K fertilizers, while Acidobacteriota Verrucomicrobiota decreased fertilizers. (3) N2P2K2 treatment produced highest sapindus (1464.58 kg/ha), which increased by 258.67% above control. (4) Redundancy analysis (RDA) primary determinants community structure were pH, total K, effective concentration. (5) Structural equation modeling (SEM) nutrient content main direct factor driving whereas attributes (e.g., diversity structure) had minor yield. summary, rational use formulated change structure, diversity, content, latter exerting effect improvement mukorossi.

The purpose of this study was to evaluate the effects different nitrogen (N), phosphorus (P), and potassium (K) fertilization ratios on carbon (C), N, P contents their ecological stoichiometric characteristics in leaf–soil–microbial system Sapindus saponaria elucidate relationship with yield. A “3414” experimental design employed a 6-year-old woodland located Fujian Province China. Fourteen N–P–K treatments three replicates were established. Leaf, soil, microbial samples collected analyzed for C, contents. Redundancy Analysis (RDA), Partial Least Squares Path Modeling (PLS–PM), entropy-weighted technique ranking preferences by similarity optimal solutions (TOPSIS) utilized assess relationships among variables determine strategies. It found through research that treatment methods have significant impact both soil nutrient content microorganisms. Compared control group, organic total P, increased 14.25% 52.61%, 3.90% 39.84%, 9.52% 150%, 6.65% 47.45%, 11.84% 46.50%, 14.91% 201.98%, respectively. Results from (RDA) indicated exerted influence leaf nutrients. PLS-PM demonstrated indirectly affected accumulation yield altering properties, being key determinants Additionally, entropy impacted regulating biomass ratios. TOPSIS model identified N2P2K2 (600 kg/ha 500 400 K) as most effective strategy. Optimizing significantly enhances thereby increasing This clarifies underlying mechanisms which exerts an C–N–P stoichiometry within system. Moreover, it furnishes scientific foundation optimization management strategies plantations.
