浏阳烟区;土壤有机质;全氮;有效磷;有效钾
摘  要:
对浏阳烟区246个土壤样本的主要养分含量的调查及其之间关系的分析,结果表明:①浏阳烟区土壤有机质、全氮和有效钾含量丰富,平均分别为32.31 g/kg、1.99 g/kg和136.98 mg/kg;有效磷含量较高,平均为20.54 g/kg。②浏阳不同烟区的有机质和全氮含量高低顺序是:浏阳西>浏阳东>浏阳北;有效磷:浏阳东>浏阳西>浏阳北;有效钾:浏阳北>浏阳西>浏阳东。③不同土壤类型的有机质含量的高低顺序是:青泥田>黄泥田>红黄泥>河砂泥>沙泥田;全氮为青泥田、黄泥田>红黄泥>河砂泥>沙泥田;有效磷为红黄泥>黄泥田>青泥田>沙泥田>河砂泥;有效钾为红黄泥>黄泥田>河砂泥>青泥田>沙泥田。④土壤有机质与全氮、有效磷、有效钾含量均呈显著正相关,并建立了回归方程。

摘  要:
Relationship between mainly soil nutrient content in 246 soil samples from Hunan tobacco-growing areas was studied.The results indicated that:①The content of Soil organic matter and otal nitrogen in Liuyang tobacco-growing areas was abundance,with mean of 32.31 g/kg,1.99 g/kg and 136.98 mg/kg;Available phosphorus content was high with mean of 20.54 g/kg.②The ordering of soil organic matter and total nitrogen in difference tobacco-growing areas of Liuyang was: west Liuyang >East Liuyang > North Liuyang;Available phosphorus: East Liuyang >west Liuyang > North Liuyang;Available potassium: North Liuyang > west Liuyang > East Liuyang.③The ordering of organic matter content in different soil types was: blue mud field > yellow mud field > red yellow mud > river sand mud > sand mud field;Total nitrogen: blue mud field,yellow mud field > red yellow mud > river sand mud > sand mud field;Available phosphorus: red yellow mud > yellow mud field > blue mud field > sand mud field > river sand mud;Available potassium: red yellow mud > yellow mud field > river sand mud > blue mud field > sand mud field.④The positive correlation coefficients of soil organic matter content and Total nitrogen,available phosphorus,available potassium and so on were significant at 0.05 level,and the regression equations were built.
