摘要
目的鉴于目前全球盐碱地比例较高，寻找一种低耗高效的盐碱地修复方法至关重要，同时还能减轻环境污染和优化农林废弃物管理。方法提取植物生长促进根瘤菌（PGPR）Wu15，并接种到生物炭上制备 BC-Wu15，通过盆栽实验验证生物炭对土壤质量和植物生长的影响。土壤养分含量（包括氮（N）、磷（P）和钾（K））以及有机质（OM）含量和阳离子交换容量（CEC）都有所增加。生物炭和 Wu15 的协同作用使冰草的叶绿素 a 和叶绿素 b 水平分别提高了 79.95% 和 81.52%。冗余分析（RDA）证实，植物生长的改善与土壤质量的提高呈正相关。这项研究为利用 BC-Wu15 作为改良盐碱土壤和提高作物产量的有效方法提供了有益的启示，证明了生物炭和 PGPR 的综合利用潜力。
Enterobacter hormaechei Wu15-loaded biochar enhances the ice plant growth by improving saline soil quality
Aim
Considering that the current proportion of saline-alkaline land worldwide is relatively high, it is vital to find a low-consumption and high-efficiency method for saline-alkaline land restoration, while at the same time, mitigating environmental contamination and optimizing agroforestry waste management.
Methods
Plant Growth Promoting Rhizobacteria (PGPR) Wu15 was extracted and inoculated onto biochar to prepare BC-Wu15, and the effects of biochar on soil quality and plant growth were verified by potting experiments.
Results
Soil quality and fertility of saline soils was proved to be improved. There was an increase in soil nutrient contents (incl. nitrogen (N), phosphorus (P) and potassium (K)) as well as in organic matter (OM) content and cation exchange capacity (CEC). The synergistic effect of biochar and Wu15 led to an increase by 79.95% and 81.52% in the ice plant’s chlorophyll a and chlorophyll b levels.
Conclusions
The result indicated the tightly packed vesicles were useful for transporting excessive salt in the ice plant. Redundancy analysis (RDA) confirmed that the improvement in plant growth was positively correlated with enhanced soil quality. This study provides useful insights into the utilization of BC-Wu15 as an effective method for amending saline soils and increasing crop yields, demonstrating the potential for the combined utilization of biochar and PGPR.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
