Saline-alkali soil imposes severe adverse effects on utilization and agriculture production worldwide. Amelioration of saline-alkali is crucial to ensure global food security promote sustainable agricultural development. Here, the combined application amendment desulfurization gypsum (G) KIA (K, an industrial organic by-product) improvement plant growth were investigated. Two experiments, a column leaching test pot experiment for growth, carried out. The results showed that G K reduced pH significantly. Although Na+ contents had no change in treatments, K+, Ca2+ Mg2+ significantly higher, HCO3− Cl− lower, compared control. Furthermore, maize plants exhibited higher photosynthetic rate greater dry weight treatments. Additionally, after enzyme activities increased. These could have more favorable impact by reducing pH, enhancing ion exchange, increasing nutrient contents, promoting growth. Our study suggests effective eco-friendly improving soil.

Intercropping legumes is an effective and sustainable planting pattern that has the benefit of decreasing chemical fertilizer input improving soil environment. However, effects reduction intercropping different on nutrients, microorganisms, tea quality remain elusive. Hereby, compared with 100% (CK), Sesbania cannabina (SC) Crotalaria pallida Blanco (CP) were selected as intercropped plant 70% to investigate its effect quality. The results showed monocropping, had greater concentrations labile organic matter, nitrate nitrogen, ammonia inorganic alkali-hydrolyzable nitrogen. systems significantly enhanced content non-ester-type catechins (catechin gallocatechin) ester-type (epicatechin gallate). In SC, gallocatechin, catechin, epicatechin gallate increased by 146.67%, 107.69%, 21.05%, respectively, while in CP, these three compounds 166.67%, 84.62%, 19.08%, respectively. Significant differences microbial composition also observed under systems. Actinobacteria, Rhodoplanes, Thaumarchaeota obviously Rhodanobacter, Pseudolabrys, Pedosphaera manifestly improved CP those monoculture. Moreover, abundances CNP cycling functional genes, such gpmB, mch, accD6, pgi-pmi, mcr, glmS, ACOX1 fadB (carbohydrate metabolism), nirD narI (nitrification), pmoB-amoB hao (dissimilatory N reduction), phoN (organic phosphoester hydrolysis). relationship between qualities was mainly established nutrition abundance C microorganisms. This study provides more information genes tea/legume plantations offers a basis for higher-performance pattern.

Salt-tolerant plants (STPs) play an important role in saline-alkali soil remediation, but their interaction with microorganisms remain incompletely elucidated. This study explored the effects on microbial community structure, function, and quality land of four treatments: no plant (CK), Triticum aestivum L. (TA), Tamarix chinensis Lour. (TC), Hibiscus moscheutos Linn. (HM). The results indicated that planting TC, TA, HM effectively reduced electrical conductivity (EC) by 82.9, 88.3, 86.2%, respectively. TC TA significantly decreased pH from 8.79 to 8.35 8.06, respectively, (p < 0.05). Moreover, nutrient content enzymatic activities were enhanced. Notably, exhibited most significant improvement.
