摘　　要：对湖南省内 2 4个茶场的 110个土壤样品的表土 (0— 2 0cm)和底土 (2 0— 40cm)两个土层的有效硫含量、全硫含量、有机质含量、以及pH值进行了测定分析。研究结果表明 :湖南省茶园土壤有效硫含量较高 ,表土的有效硫含量为 6 4 8± 6 2mgS kg (范围 :12 2— 2 10 2mgS kg) ,底土的有效硫含量为 91 8± 8 4mgS kg (范围 :11 1— 2 35 1mgS kg) ,但仍有 7 3 %茶园土壤缺硫 ;0— 2 0cm土层的有效硫有向 2 0— 40cm土层下移的倾向 ;土壤有效硫与土壤全硫呈显著正相关 ,与pH值呈显著负相关 ,与有机质相关关系不明显 ;The contents of available sulphur,whole sulphur,organic matter and pH of 110 samples of surface soil (0—20cm) and subsoil(20—40 cm),which sampled from 24 tea plantations in Hunan Province,were analyzed The results indicated that the contents of available sulphur in tea gardens were rather high,averaged 64 8±6 2 mg/kg,ranging 12 2—210 2 mg/kg in surface soils,and averaged 91 8±8 4 mg/kg at the range from 11 1 to 235 1 mg/kg in subsoil There were about 7 3 per cent of tea garden soils in Hunan Province being S deficient There was a tendency that available sulphur transferred from surface soil to subsoil in tea garden The content of available sulphur was of remarkable positive correlation to the content of whole sulphur,but remarkable negative correlation to pH and no significant correlation to the content of organic matter The contents of both available sulphur and whole sulphur were related to soil parent materials
