| 中文摘要: |
| 本研究旨在探讨不同浓度液肥对土壤改良效果的影响。试验设置了低浓度液肥（稀释200倍）、高浓度液肥（稀释20倍）及对照组，对比分析其对土壤pH值、电导率（EC）、有机质含量、氮、磷、钾及微量元素的影响。结果表明，高浓度液肥在施用初期能显著降低土壤pH值，提升全氮和碱解氮含量，而低浓度液肥在提高土壤有机质和有效磷含量方面表现更为稳定，两种浓度的液肥均显著提高了土壤电导率，低浓度液肥因其作用持久性和较小的pH值波动影响，更适合长期土壤管理。 |
| 英文摘要: |
| This study aimed to investigate the effects of different concentrations of liquid fertilizer on soil improvement. A field experiment was conducted with three treatments: low-concentration liquid fertilizer (diluted 200-fold), high-concentration liquid fertilizer (diluted 20-fold), and a control. Their effects on soil pH, electrical conductivity (EC), organic matter content, and the levels of nitrogen, phosphorus, potassium, and trace elements were compared and analyzed. The results indicated that, in the early stage of application, high-concentration liquid fertilizer significantly reduced soil pH and increased the content of total nitrogen and alkali-hydrolyzable nitrogen. In contrast, low-concentration liquid fertilizer was more consistent in increasing soil organic matter and available phosphorus content. Due to its sustained effects and smaller fluctuations in pH, low-concentration liquid fertilizer is more suitable for long-term soil management. |
