摘  要：
对信阳毛尖产地(浉河区、罗山县)土壤p H、有机质和有效硫、镁现状进行研究,为茶园科学合理施肥提供借鉴。研究表明,信阳毛尖产地茶园土壤p H和有机质含量分别在3.26~6.30和1.57~85.71g kg-1之间,有效硫和有效镁含量分别在8.59~134.30 mg kg-1和48.70~2408.00 mg kg-1之间。土壤有效硫含量较低,缺乏和含量一般的茶园占调查总数的80%以上,且地域差异性较大;近95%的茶园土壤镁含量较高;同时,有83%以上的茶园缺乏土壤有机质,约有2/3的茶园土壤p H值低于4.5,茶园土壤的酸化较为严重。此外,茶园中土壤有效硫与p H、有机质之间均存在较低的负相关性,土壤有效镁与p H呈极显著正相关关系,土壤有效镁与有机质则呈一定的负相关关系。

摘  要：
This research analyzed the con tents of soil available S, available Mg, organic matter and p H in Shihe District and Luoshan County, where Xinyangmaojian tea was planted, in order to provide support for scientific and reasonable fertilization in the soil of tea garden. The results showed that the contents of soil available S and available Mg were 8.59 ~ 134.30 mg kg-1and 48.70 ~ 2408.00 mg kg-1, respectively. And soil p H and soil organic matter contents were 3.26 ~ 6.30 and 1.57 ~ 85.71 g kg-1, respectively. Moreover, more than 80% of soil available S belonged to low and general level. There was significant difference in available S between different sites. Above 95% of available Mg belonged to high level. More than 83% of soil organic matter was lack. About 2/3 of soil p H was lower than 4.5, which indicated the soil in tea garden was seriously acidified. Additionally, there was a little negative correlation between soil available S and p H, soil organic matter, respectively. Soil available Mg was positively correlated with soil organic matter and negatively correlated with soil p H.
