Abstract
Applying biochar has beneficial effects on regulating plant growth by providing water and nutrient availability for plants due to its physicochemical characteristics. Nevertheless, it is still unclear how soil and biochar interactions strengthen crop lodging resistance. The objective of the current study was to find out how soil physicochemical conditions and alterations in biochar affect lodging resistance and crop productivity in cereals. To do this, a meta-analysis was carried out using nine groups of effective variables including type of feedstock, pyrolysis temperature, application rate, soil pH, total nitrogen, available phosphorus, potassium, organic matter (OM), and soil texture. Results showed that straw-derived biochar caused the highest positive effect size in the dry weight of biomass (20.5%) and grain yield (19.9%). Also, the lowest lodging index was observed from straw (−8.3%) and wood-based (−5.6%) biochars. Besides, the high application rate of biochar results in the highest positive effect sizes of plant cellulose (8.1%) and lignin content (7.6%). Soils that contain >20 g kg−1 OM, resulted in the highest positive effect size in dry biomass (27.9%), grain yield (30.2%), and plant height (4.7%). Also, fine-textured soil plays an important role in increasing polymers in the anatomical structure of plants. Overall, the strong connection between biochar and soil processes, particularly the availability of OM, could strengthen plants' ability to tolerate lodging stress and contribute to high nutrient efficiency in terms of crop output and cell wall thickening.
由于生物炭的理化特性，施用生物炭能为植物提供水分和养分，从而对植物生长产生有益的调节作用。然而，目前还不清楚土壤和生物炭之间的相互作用如何增强作物的抗倒伏能力。本研究的目的是了解土壤理化条件和生物炭的变化如何影响谷物的抗倒伏性和作物产量。为此，利用九组有效变量进行了元分析，包括原料类型、热解温度、施用量、土壤 pH 值、全氮、可利用磷、钾、有机质（OM）和土壤质地。结果表明，秸秆生物炭对生物质干重（20.5%）和谷物产量（19.9%）的积极影响最大。同时，秸秆生物炭（-8.3%）和木质生物炭（-5.6%）的抗倒伏指数最低。此外，生物炭的高施用量对植物纤维素（8.1%）和木质素含量（7.6%）的积极影响最大。含 20 g kg-1 OM 的土壤对干生物量（27.9%）、谷物产量（30.2%）和植株高度（4.7%）的正效应最大。此外，细粒土壤在增加植物解剖结构中的聚合物方面也发挥了重要作用。总之，生物炭与土壤过程之间的紧密联系，尤其是 OM 的可用性，可以增强植物对宿根胁迫的耐受能力，并有助于提高作物产量和细胞壁增厚方面的养分效率。
期刊介绍：
Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement.
Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB.
Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
