摘要

背景：腐植酸（HA）、生物炭基微生物剂(M)和蚯蚓堆肥(V)已被证明具有改善土壤结构和提高作物产量的作用。然而，这些改良剂对盐碱地棉花生长、光合特性、产量和纤维品质的综合影响尚不清楚。结果：本研究结果表明：(1)与对照（CK）相比，HA、M和V单独施用和组合施用增加了土壤储水量，降低了土壤盐分；（ii） HA、M和V配施对水稻株高、茎粗、叶面积指数、净光合速率、气孔导度、胞间CO2浓度、蒸腾速率、SPAD、生物量和产量的改善效果最大，分别提高了39.2%、36.0%、88.1%、43.9%、97.8%、41.1%、133.9%、18.0%、85.1%和31.8%；（iii） HA、M和V的最佳施用量分别为120、60和120 kg HA -1；（iv）相关分析和结构方程建模表明，棉花产量与生物量、生长指标和光合特性呈正相关，而纤维品质与光合特性、土壤水分储量和产量呈正相关。结论：在盐碱地中，推荐采用HA、M、V复合施用促进棉花生长。©2025化学工业协会。

Humic acid, biochar-based microbial agent and vermicompost improve cotton growth, photosynthesis, yield and fiber quality in saline-alkali soil.

Background: Humic acid (HA), biochar-based microbial agent (M) and vermicompost (V) have been shown to improve soil structure and increase crop yields. However, the combined effects of these amendments on cotton growth, photosynthetic characteristics, yield and fiber quality in saline-alkali soils remain unclear.

Results: The results obtained in the present study showed that: (i) compared to the control (CK), the single and combined applications of HA, M and V increased soil water storage and reduced soil salinity; (ii) the combined application of HA, M and V resulted in the greatest improvements in plant height, stem diameter, leaf area index, net photosynthetic rate, stomatal conductance, intercellular CO₂ concentration, transpiration rate, SPAD, biomass and yield, with increases of 39.2%, 36.0%, 88.1%, 43.9%, 97.8%, 41.1%, 133.9%, 18.0%, 85.1% and 31.8%, respectively; (iii) the optimal application rates of HA, M and V were 120, 60 and 120 kg ha^-1, respectively; (iv) correlation analysis and structural equation modeling revealed that cotton yield was positively correlated with biomass, growth indices and photosynthetic characteristics, whereas fiber quality was positively correlated with photosynthetic characteristics, soil water storage and yield.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
