Cotton root systems sustain photosynthesis by nutrient uptake and coordinate with above-ground growth to influence yield. This study explored the effects of fulvic acid (FA) phosphorus (P) fertilizers on relationships between cotton photosynthetic capacity (CAP) carbohydrate metabolism. A field experiment was conducted including five treatments: no P fertilizer (CK), 105 kg P2O5 ha−1 (P1), 150 (P2), + FA (FP1), (FP2). Results found that FP2 showed most significant advantage, ensuring a suitable leaf area index (LAI) fractional interception photosynthetically active radiation (IPAR) consequently maintaining high CAP. Compared FP2, FP1 resulted in an increase boll loading system (BLR) 8.1% (BCR) 9.3%. From peak flowering stage setting stage, sucrose starch contents were 6.2–19.2% 26.5–27.9% lower than those respectively. Conversely, fructose glucose 6.4–10.8% 7.2–8.8% higher FP2. The reproductive organ biomass increased 11.1% 14.7% relative Moreover, achieved highest yield, 8.5% 11.0% compared P2 Taken together, our suggests application (105 FA) could be proper fertilization method production saline-alkali arid regions.
