【摘要】 为探究夏季间作红花合欢（Albizia julibrissin）与重度覆盖遮阴方式对茶园土壤养分结构及茶叶品质的影响，设置3组处理：红花合欢间作、95%重度遮阴和对照（CK），分别于处理后第0、4、12天采集土壤及茶叶样本。通过电位法、分光光度法等测定土壤pH值、有机质、全效养分和速效养分含量，同时分析绿茶和红茶的感官品质及理化成分（茶多酚、氨基酸、酚氨比等）。试验结果表明，间作红花合欢可显著改善茶叶酚氨比，鲜爽度提升，感官评分最高（绿茶90.8分，红茶92.8分）。土壤养分方面，间作方式土壤有机质、全氮及阳离子交换量均显著高于其他处理，速效钾和有效磷含量亦保持较高水平。重度遮阴方式虽可提高游离氨基酸含量，但土壤养分改善效果不明显。综上，红花合欢间作方式通过调节土壤养分结构及微气候环境促进茶树代谢，显著提升夏季茶叶品质，效果优于常规遮阴方式。未来需进一步优化间作密度与遮阴方式，探索其在不同生态茶园的适用性，为茶叶产业可持续发展提供技术支撑。更多还原

【Abstract】 Existing research primarily in order to investigate the effects of summer intercropping with Albizia julibrissin and heavy shade cover on the soil nutrients structure and tea quality in tea plantations, three treatment groups were set up: intercropping with Albizia Julibrissin, 95% heavy shade and control(CK), and the soil and tea samples were collected on the 0th, 4th, and 12th days after the treatments, respectively. Soil pH, organic matter, total nutrient and quick-acting nutrient contents were determined by potentiometric and spectrophotometric methods, and the sensory quality and physicochemical compositions(tea polyphenols, amino acids, phenolammonia ratio, etc.) of the green and black tea were analyzed at the same time. The experimental results showed that intercropping with safflower acacia significantly improved the phenol-ammonia ratio of tea leaves, freshness and freshness, and the highest organoleptic scores(90.8 points for green tea and 92.8 points for black tea). In terms of soil nutrients, soil organic matter, total nitrogen and cation exchange were significantly higher in the intercropping approach than in the other treatments, and the content of quick-acting potassium and effective phosphorus also remained high. Although the heavy shade method could increase the free amino acid content,the soil nutrients improvement effect was not obvious. In conclusion, the intercropping of saffron acacia promoted the metabolism of the tea tree by adjusting the soil nutrients structure and microclimate environment, and significantly improved the quality of tea leaves in summer, which was better than that of the conventional shading method. In the future, we need to further optimize the intercropping density and shading method, explore its applicability in different ecological tea gardens, and provide technical support for the sustainable development of tea industry.更多还原
