Path analysis further showed that RA, SD, and RBR were the key factors influencing GQI. Further multiple linear regression analysis indicated that SD (Beta = 0.559) and RA (Beta = 0.369) had significant direct effects on GQI, while RBR mainly regulated GQI formation through indirect pathways. Overall, BS75+C emerged as a sustainable and efficient soil management strategy, capable of simultaneously improving root development, plant growth, and yield (151,341 kg ha⁻ 1 ) under greenhouse conditions in arid and semi-arid environments. BS25, however, provided the highest economic benefit (672,361.04 yuan ha⁻ 1 ), offering a more cost-effective alternative under current production conditions.
