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. STPs also substantially altered structure increasing bacterial richness (ACE Chao1 indices) compared other treatments promoted relative abundance unclassified_Gemmatimonadaceae, unclassified_Vicinamibacterales, Mortierella A major innovation this is using network analysis explore interactions, revealing how enhance complexity. approach identified Sphingomonas as a key taxon soils, shedding light dynamics remediation. Additionally, partial least squares path model (PLS-PM) showed improvements primarily driven shifts composition, offering novel mechanistic framework for understanding contributions restoration. research advances microbial-plant interactions underscores innovative application phytoremediation, valuable insights future restoration strategies.

Optimizing Phosphorus Fertilization Management Is Conducive to Improving Alfalfa Yield and Quality: A Meta-Analysis

Agriculture, Journal Year: 2025, Volume and Issue: 15(8), P. 797 - 797

Published: April 8, 2025

The addition of phosphorus fertilizer plays a critical role in improving alfalfa yield and quality. However, improper application may lead to resource waste environmental pollution, its effects are influenced by multiple factors. This study quantitatively analyzed the fertilization on yield, crude protein (CP) content, acid detergent fiber (ADF) neutral (NDF) content their major influencing factors using meta-analysis method integrating data from published field experiments. results showed that, compared no application, increased CP NDF 19.0% (confidence interval [CI]: 15.4–22.6%), 7.2% (CI: 0.1–14.9%), respectively, while reducing ADF 3.3% average 0.9–3.3%). In Shandong, Jilin, Hebei, where soil pH is 7–8, annual precipitation 200–400 mm, mean temperature above 4 °C, altitude 500–1000 m, improved after applying calcium phosphate or single superphosphate with P2O5 0–20% at rate 100–200 kg·ha−1, along nitrogen > 100 when both test establishment periods were 2 years. Xinjiang, regions an 6–8 °C duration 3 years, provides references for enhancing productivity efficient utilization nutrition.
