| 摘 要： | 对湖南省194个典型茶园土壤微量元素有效量进行了调查，结果表明：茶园土壤有效态zn、Cu、Mn、Fe含量分别为1．94mg／kg、151．23mg／kg、85．95mg／kg、7．07mg／kg；有效铁的含量较丰富，98．5％茶园土壤有效铁含量〉10mg／kg；有效铜、有效锰、有效锌的含量相对偏低，低于临界值的茶园分别占32％、28．4％、12．4％。有效铜、有效锰与pH值呈极显著正相关，有效Zn和有机质呈极显著正相关，与pH值呈极显著负相关。

| Abstract: | The available content of soil trace elements in 194 Hunan tea gardens was surveyed and analyzed. The result showed that the available content of Zn, Cu, Mn and Fe was 1.94mg/kg, 151.23mg/kg, 85.95mg/kg and 7.07mg/kg respectively. The available content of Fe is comparatively rich and 98.5% surveyed tea gardens have more than 10mg/kg content. The available content ofZn, Cu and Mn is comparatively low with 32%, 28.4% and 12.4% tea gardens below the critical content. Available Cu and available Mn has an extremely significant positive with pH value. Available Zn has an extremely significant positive correlation with organic matter, while has an extremely significant negative correlation with pH value. |
