- 摘要:
- 为了解贵州铜仁茶园土壤交换性钙、交换性镁和交换性硫含量特征,对印江、思南、松桃、石阡和沿河5个主产茶区143个茶园土壤样品进行测定,并分析其与茶园土壤pH、有机质含量间的相关关系。结果表明:印江和思南茶园土壤交换性钙含量极显著高于其它茶区,土壤交换性钙含量超标;石阡和松桃分别有55.17%和40.00%达到Ⅰ级土壤标准,土壤交换性钙含量丰富;沿河茶园土壤交换性钙平均值仅为314.4 mg?kg-1,有70.00%的土样处于Ⅲ级土壤标准,交换性钙含量缺乏。铜仁各茶区茶园土壤交换性镁含量平均值均高于Ⅰ级土壤标准临界值,印江全部达到Ⅰ级土壤标准和高产优质茶园土壤标准;沿河有66.67%的土样处于Ⅲ级土壤标准,土壤交换性镁含量缺乏。思南、松桃和石阡茶园土壤交换性硫含量丰富;印江和沿河较低,特别是沿河,有70.00%的土样处于Ⅲ级土壤标准,缺硫严重。土壤交换性钙与pH呈显著正相关,与土壤中有机质的含量呈极显著正相关,与交换性镁呈极显著正相关;土壤交换性硫与有机质呈正相关,而与土壤pH呈负相关,但相关性不显著。
- Abstract:
- In order to understand the characteristics of soil exchangeable calcium(M3-Ca),exchangeable magnesium(M3-Mg)and exchangeable sulfur(M3-S)in Tongren tea plantation in Guizhou province,143 soil samples of tea plantations in Yinjing(YJ),Sinan(SN),Songtao(ST),Shiqian(SQ)and Yanhe(YH)were measured,and analyzed the correlation between they and soil pH and organic matter(OM) content.The results showed that the M3-Ca contents of YJ and SN areas′tea plantation soils were exceeded standard,YH area was short of calcium.The average value of M3-Mg in the tea garden soils of Tongren were higher than that of gradeⅠsoil standard,YJ all reached gradeⅠsoil standard and good quality and high yield tea garden soil standard; YH was 66.67% soil samples in grade Ⅲ soil standard,the M3-Mg content is lacking.The M3-S content of SN,ST and SQ tea plantation soils were rich,YJ and YH tea plantation soils were lower,especially YH,70% of the soil samples were in the Ⅲ grade soil standards,and lack of M3-S serious.There was a significant positive correlation between M3-Ca and pH,and had a extremely significant positive correlation with OM content and M3-Mg.M3-S was positively correlated with OM and negatively correlated with pH,but the correlation was not significantly.
