| 摘 要： | 为全面了解林芝茶园土壤的肥力水平,本研究在波密县、察隅县、墨脱县、易贡茶场和察隅农场等五个茶叶主产区,从茶园及其附近农田、荒地取土91份,选取土壤有机质、pH、全氮、有效磷、速效钾、缓效钾、有效铜、有效锌、有效铁、有效锰、有效硼、有效钼、有效硫、有效硅和土壤水溶性盐总量15个评价指标,以农田土壤为对照,综合评价林芝市茶园土壤肥力。结果表明：茶园土壤有机质高于附近农田土壤;茶园土壤pH低于附近农田土壤;茶园全氮、有效磷、速效钾等土壤养分与附近农田土壤整体差异不大。茶园科学合理管理对土壤起到一定保肥能力和缓冲性能作用,但茶叶种植时间久了后会造成土壤酸化,降低土壤某些养分有效性。

| Abstract: | In order to comprehensively understand the fertility level of tea plantation soils in Linzhi, this study took 91 pieces of soil from tea plantations and nearby farmland and wasteland in five main tea producing areas, including Bomi County, Chashu County, Mutuo County, Yigong Tea Plantation and Chashu Farm, and selected 15 evaluation indexes, including soil organic matter, pH, total nitrogen, effective phosphorus, fast-acting potassium, slow-acting potassium, effective copper, effective zinc, effective iron, effective manganese, effective boron, effective molybdenum, effective sulphur, effective silica and total water-soluble salts of the soil in Linzhi City. The soil fertility of tea plantation in Linzhi City was evaluated comprehensively with 15 evaluation indexes, taking farmland soil as the control. The results showed that: the organic matter of the tea garden soil was higher than that of the nearby farmland soil; the pH of the tea garden soil was lower than that of the nearby farmland soil; and the soil nutrients of the tea garden such as total nitrogen, effective phosphorus and quick-acting potassium did not differ much from those of the nearby farmland soil as a whole. The scientific and reasonable management of the tea garden plays a certain role in the soil"s ability to retain fertiliser and buffer performance, but tea planting for a long time will cause soil acidification and reduce the effectiveness of certain soil nutrients. |
