| 中文摘要: |
| 为探究生物炭配施木醋液对河北低平原区盐碱土壤的改良效果及对冬小麦生理特征的影响，本研究设置未施生物炭（CK）、生物炭15 t·hm-2（ T0）、生物炭15 t·hm-2+225 kg·hm-2木醋液（T1）、生物炭15 t·hm-2+450 kg·hm-2木醋液（T2）和生物炭15 t·hm-2+675 kg·hm-2木醋液（T3）处理，分析了生物炭配施木醋液对盐碱土壤速效养分、pH、电导率（EC）和冬小麦植株碳氮代谢及抗氧化能力的影响。结果表明：各处理中，T2均显著提高冬小麦花后旗叶各灌浆时期的超氧化物歧化酶（SOD）和过氧化物酶（POD）活性，显著降低超氧阴离子自由基积累量，并显著提高灌浆前期的可溶性蛋白和可溶性糖含量及灌浆中期的游离氨基酸含量。T2较CK和T0处理氮总累积量提高6.4%和4.6%，磷总累积量提高16.1%和12.3%，钾总累积量提高4.7%和3.2%，且均呈显著性差异。T2较CK和T0处理均显著提高土壤硝态氮、有效磷和速效钾含量，仅在0~20 cm土层中显著降低土壤EC值，土壤pH值和有机质各处理间无显著差异。T2较CK和T0处理产量显著提高10.8%和7.9%。由拟合曲线得出生物炭配施433.75 kg·hm-2木醋液时产量最佳，该结果与T2增施量相近。研究表明，在提升河北低平原内陆轻度盐碱土壤生产能力时，建议生产实践中在增施生物炭15 t·hm-2的基础上配施木醋液量为433.75~450 kg·hm-2。 |

| To investigate the effects of biochar with wood vinegar application on saline soil improvement effect and physiological characteristics of winter wheat in the low plain area of Hebei. In this study, we set up no biochar application（CK）, 15 t·hm-2 of biochar （T0）, 15 t·hm-2 of biochar application+225 kg·hm-2 of wood vinegar（T1）, 15 t·hm-2 of biochar+450 kg·hm-2 of wood vinegar（T2）, and 15 t·hm-2 of biochar+675 kg·hm-2 of wood vinegar solution（T3）. The effects of biochar with wood vinegar on quick-acting nutrients, pH, electrical conductivity（EC）value and carbon and nitrogen metabolism and antioxidant capacity of winter wheat plants were analyzed. The results showed that, compared with the treatments, T2 significantly increased the superoxide dismutase（SOD）and peroxidase（POD） activities, significantly reduced the accumulation of superoxide anion radicals, and significantly increased the soluble protein and soluble sugar contents in the pre-filling period and the free amino acid contents in the mid-filling period of winter wheat flag leaves after flowering, and T2 significantly increased the total accumulation of nitrogen（6.4% and 4.6%）and phosphorus（16.1% and 12.3%）, respectively, compared with that of the CK and T0 treatments. T2 significantly increased the soil nitrate nitrogen, effective phosphorus and quick-acting potassium content compared with CK and T0 treatments, and significantly decreased the soil EC value only in the 0-20 cm soil layer, and there was no significant difference between the treatments in soil pH and organic matter 7.9%, showing significant differences. From the fitting curve, it was concluded that the amount of biochar with wood vinegar was the best yield at 433.75 kg·hm-2, which was similar to the increased amount of T2. In conclusion, in order to improve the production capacity of mild saline soil in the inland low plain of Hebei Province, it is recommended to add 15 t·hm-2 biochar to the production practice with the amount of wood vinegar in the range of 433.75~ 450 kg·hm-2. |
