摘要
以长沙县湘丰茶场飞跃有机茶园基地为例,采用野外调查采样、室内分析测定方法,研究了花岗岩母质发育的红壤茶园土壤肥力特征。结果表明:茶场土壤偏酸,pH值平均为4.45;有机质含量较低,平均为9.78 g/kg;土壤全氮含量很低,平均为1.13g/kg;碱解氮的含量较高,平均158.96 mg/kg;土壤全磷含量很低,平均为0.25 g/kg;有效磷含量也不高,平均为7.02 mg/kg;全钾含量较高,平均为43.96 g/kg;速效钾含量较低,平均为109.56 mg/kg。土壤肥力为中等偏低水平。
The characteristics of soil fertility in red earth tea plantation developed from granite parent material（Feiyue Organic Tea Base of Xingfeng Tea Plantation in Changsha County） were studied by using the methods of field investigation,laboratory analysis and measurement,and statistical analysis.The results showed that the soil pH was suitable for the growth of tea,its average value was 4.45;the content of soil organic matter was lower,its average value was 9.78 g/kg;the soil total N was also lower,its average value was 1.13 g/kg;the content of the alkaline hydrolysis nitrogen was higher,its average value was 158.96 mg/kg;the content of soil total phosphorus was less,its average value was 0.25 g/kg;the content of soil available phosphorus was lower,while its average value was 7.02 mg/kg;the content of soil total potassium was higher,its average value was 43.96 g/kg;the content of soil available potassium was lower,its average value was 109.56 mg/kg.
