| 摘 要： | 为了探明江西信丰县紫色土养分状况,于2009年在信丰县采集土壤样品进行化验分析,同时把信丰县紫色土区域划分为上等烟地、中等烟地、潜力烟地与后备烟地,其中上等紫色土烟地养分规律为:pH呈中性;有机质含量偏低;土壤全氮、全磷、全钾含量居中,但氮、磷、钾有效态含量均较高;有效硼与有效硫含量较高,但交换性镁含量又相对较低;上等烟土壤中微量元素铜、锌、铁、锰有效态含量均较低。

| Abstract: | In order to investigate the nutrient status of purple soil in Xinfeng tobacco-planting area of Jiangxi province,the soil samples from Xinfeng county were collected and analyzed in 2009.The purple soil region in Xinfeng county was divided into the following four types: good tobacco-planting land,medium tobacco-planting land,potential tobacco-planting land and reserved tobacco-planting land.In the good tobacco-planting land of purple soil region,the soil pH-value was neutral;the organic matter content was slightly low;the contents of total nitrogen,phosphorus and potassium were medium;the contents of available nitrogen,phosphorus,potassium,boron and sulfur were higher;the exchangeable magnesium content was relatively lower;the contents of available trace elements(copper,zinc,iron and manganese) in the soil were lower. |
