| 中文摘要: |
| 本研究以临沂市兰陵县酸化盐渍土和黄瓜植株为对象，系统评价钙基土壤改良剂对土壤改良的效果及其对黄瓜生长和抗逆性的影响，通过物理、化学和生物学指标及相关性分析等，探究其关键作用机制，并确定该地区钙基土壤改良剂的最佳施用量。试验设置5个处理：以不施钙基土壤改良剂为对照（CK），同时设置钙基土壤改良剂4个不同用量的处理组，添加量分别为3 t·hm-2（T1）、6 t·hm-2（T2）、12 t·hm-2（T3）和18 t·hm-2（T4）。结果表明：添加钙基土壤改良剂缓解了土壤酸化问题，显著降低了土壤容重、土壤全盐量、土层积盐量和钠吸附比。T3和T4显著提高了黄瓜的产量，产量较CK分别提升了46.74%和42.80%。添加钙基改良剂处理的土壤团聚体、团聚体平均质量直径、微生物生物量碳氮、钙镁离子以及黄瓜的株高、茎粗、叶面积、根长、根粗、地上地下生物量、根系活力、叶绿素、维生素C等较CK有显著提升。添加钙基改良剂降低了超氧化物歧化酶和过氧化氢酶活性，从而增强了黄瓜植株的抗逆性。与T1相比，T3和T4的土壤质量指数分别提升了162.79%和186.89%。此外，通过Mantel检验和Pearson相关性分析发现，钙基改良剂提升土壤生态功能和黄瓜品质的关键在于降低盐渍化程度，优化钙、镁、钾等养分的供应。研究表明，T3和T4组的土壤质量指数、黄瓜产量及抗逆性显著高于其他试验组。钙基土壤改良剂可作为酸性盐渍土壤的改良剂，并且添加12~18 t·hm-2可以更好地提高土壤质量指数。 |

| This study systematically evaluated the effects of calcium-based soil conditioners on soil improvement and cucumber growth and resistance in the acidified saline soil of Lanling County, Linyi City. Their key improvement mechanisms and the optimal application rate were determined through physical, chemical and biological indicators and correlation analyses. Treatment without any soil amendment was served as control（CK）. Additionally, four treatments with different dosages of calcium-based soil amendment were set up, namely 3 t·hm-2（T1）, 6 t·hm-2（T2）, 12 t·hm-2（T3） and 18 t·hm-2（T4）. Adding calcium-based soil amendments alleviated soil acidification and significantly reduced soil bulk weight, total soil salinity, soil salt accumulation and sodium adsorption ratio. Compared with CK, T3 and T4 treatments significantly increased the cucumber yield by 46.74% and 42.80%, respectively. The calcium-based amendment improved the soil aggregates, average mass diameter of aggregates, microbial biomass carbon and nitrogen, calcium and magnesium ions, plant height, stem thickness, leaf area, root length, root thickness, above-ground and below-ground biomass, root vigor, chlorophyll, and vitamin C of cucumber. The addition of calcium-based amendments increased the resistance of cucumber plants, as a result of attenuated superoxide dismutase and catalase activities. Compared with T1, the soil quality indexes in T3 and T4 were enhanced by 162.79% and 186.89%, respectively. In addition, Mantel Test and Pearson correlation analyses revealed that the key to enhance soil ecological function and cucumber quality with calcium-based amendments lied in reducing salinity and optimizing the supply of nutrients such as calcium, magnesium and potassium. In conclusion, T3 and T4 treatments exhibited significantly higher soil quality indexes, cucumber yields, and stress resistance compared to other treatments. Thus, calcium-based soil conditioner effectively remediate acidified saline soil with an optimal addition of 12-18 t·hm-2, achieving the most pronounced improvement in soil quality index. |
