梅州地区茶园土壤微量元素及微生物调查

调查了梅州地区代表性茶区土壤微量元素及土壤微生物状况。结果表明，所调查的梅州3个茶区土壤有效铁含量丰富，未出现低于临界值样本；土壤有效硼含量较丰富，仅汤坑茶区9．09％土壤有效硼含量低于缺硼临界值；而有效铜和有效锌含量除汤坑茶区未发现低于临界值样品外．其他2个茶区缺乏均较严重。土壤有效锰含量均出现低于临界值样品，以清凉山茶区缺乏较严重。土壤细菌在微生物群落中处于优势地位，土壤放线菌和固氮菌与多种养分因子之间呈显著或极显著相关。...

Summary:调查了梅州地区代表性茶区土壤微量元素及土壤微生物状况。结果表明，所调查的梅州3个茶区土壤有效铁含量丰富，未出现低于临界值样本；土壤有效硼含量较丰富，仅汤坑茶区9．09％土壤有效硼含量低于缺硼临界值；而有效铜和有效锌含量除汤坑茶区未发现低于临界值样品外．其他2个茶区缺乏均较严重。土壤有效锰含量均出现低于临界值样品，以清凉山茶区缺乏较严重。土壤细菌在微生物群落中处于优势地位，土壤放线菌和固氮菌与多种养分因子之间呈显著或极显著相关。

The soil trace elements and soil microorganism of representative tea garden in Meizhou area were surveyed. The results show that 3 tea areas soil investigated in Meizhou were rich in effective iron, no soil sample below the critical value was found. Soil effective boron was rich, only 9~09% soil samples of Tang-keng area were lower than effective boron critical value. However, the content of effective copper and zinc were serious lack, but there was no sample lower than critical value in Tang-keng tea garden area. The effective manganese were deficiency in these 3 tea garden areas, especially in Qing-liang Mountain tea area. The bacterium quantity was advantage in soil microflora. Soil antinomycetc and azotobacter were significant correlation with many kinds of nutrients.
