| 摘要: |
| 【目的】为缓解猕猴桃园连作障碍，系统探究有机土壤调理剂与富氢水配施对土壤养分赋存特征及肥力水平的协同增效机制。【方法】设置了不施肥（CK）、常规施肥+常规水（NW）、常规施肥+富氢水（NM）、土壤调理剂+常规水（BW）、土壤调理剂+富氢水（BM）、50%土壤调理剂+50%常规肥料+富氢水（HBNM）共6个处理，采用内梅罗综合指数等方法构建了土壤综合肥力评价体系，结合主要驱动因子，研究土壤调理剂与富氢水对土壤理化性状、养分量及综合肥力特征的影响。【结果】①施肥可以显著提升土壤养分水平，BM处理的综合肥力指数（IFI）最高，为2.84，而HBNM处理的IFI偏低。②肥力因子权重表现为速效磷（AP）＞速效氮（AN）＞全磷（TP）＞全氮（TN）＞有机碳（SOC）＞pH值＞全钾（TK）＞速效钾（AK）。SOC与TN、TP、AP、AK均极显著正相关（P＜0.001），与pH值极显著负相关（P＜0.001）。③土壤调理剂与富氢水配施能有效改善土壤理化性质，显著提升养分含量与综合肥力。【结论】土壤调理剂+富氢水处理表现出显著的协同增效效应；建议在猕猴桃生产中推广该配施模式，并进一步加强氮素形态转化调控与肥料合理配比。 |

| Abstract: |
| 【Objective】Continuous monoculture in orchards can lead to soil degradation and nutrient imbalances, compromising fruit yield and sustainability. Applying organic soil conditioners can alleviate these detrimental effects. This paper presents the results of an experimental study on the combined effects of applying organic soil conditioner and hydrogen-rich water on soil nutrient fertility in a kiwifruit orchard.【Method】The experiment included six treatments: no fertilization (CK), conventional fertilization + conventional irrigation (NW), conventional fertilization + irrigation with hydrogen-rich water (NM), application of organic soil conditioner + irrigation with conventional water (BW), application of organic soil conditioner + irrigation with hydrogen-rich water (BM), and application of 50 % organic soil conditioner and 50% conventional fertilizer + irrigation with hydrogen-rich water (HBNM). During the experiment, we measured soil physicochemical properties, nutrient contents and soil fertility. The effects of the treatments on soil fertility were evaluated using the Nemerow composite index combined with analysis of key driving factors.【Result】Fertilization significantly increased soil nutrients, including total nitrogen (TN) and total phosphorus (TP), compared to CK. Among all treatments, BM achieved the highest integrated fertility index (IFI = 2.84) and the greatest increases in SOC and available nutrients; it also enhanced nutrient accumulation and biological activity in the soil. HBNM gave the lowest IFI, indicating diminished nutrient supply. The contribution of various factors to soil fertility was ranked in the order AP (available phosphorus)＞AN (available nitrogen)＞TP＞TN＞SOC (soil organic carbon)＞pH＞TK (total potassium)＞AK (available potassium). SOC was positively correlated with TN, TP, AP, and AK (P＜0.001), and negatively correlated with pH (P＜0.001), underscoring its importance in soil fertility.【Conclusion】Applying soil conditioner and hydrogen-rich water can effectively improve soil physical and chemical properties, significantly increase nutrient contents and enhance overall soil fertility. It can be used as an improved cultivation practice for sustainable kiwifruit production. |
