The yield and quality of rice are influenced by soil conditions, the issues in saline–alkaline land limit agricultural productivity. fields northern irrigation area Yinchuan, Ningxia, China, face challenges such as low yield, poor quality, fertilizer utilization efficiency, salinity alkalinity obstacles. To improve this situation, study conducted experiments 2022–2023 rice–crab integrated Tongbei Village, Tonggui Township, Yinchuan. This employed a single-factor comparative design, applying 150 mL·hm−2 brassinolide (A1), 15 kg·hm−2 diatomaceous (A2), 30 Bacillus subtilis agent (A3), an untreated control (CK) to analyze effects different biological amendments on growth, photosynthesis, microbial communities. results indicated that, compared with CK, A3 increased SPAD value net photosynthetic rate 2.26% 28.59%, respectively. Rice 12.34%, water use efficiency (WUE) 10.67%, palatability score 2.82%, while amylose content decreased 8.00%. bacterial OTUs (Operational Taxonomic Units) fungal 2.18% 22.39%, Under condition showed superior highest (8804.4 kg·hm−2), OTUs. These findings provide theoretical technical support for utilizing remediation agents achieve desalinization, enhancement, improvement, saline–alkali co–culture paddies.
