摘要：	分析了湖南嘉禾1375个植烟土壤样本28个不同土壤种类的肥力特征和物理性状，并对不同土壤种类的肥力状况和物理性状相关性进行分析。结果表明:（1）嘉禾植烟土壤中浅灰黄泥、灰泥田、青鸭屎泥和灰黄泥占50%左右；土壤略偏碱；有机质均较丰富，平均为44.91g/kg；碱解氮含量丰富，平均为176.32mg/kg；有效磷含量适宜，绝大多数土壤类型有效磷含量在10-20mg/kg的适宜范围内；大部分土壤类型速效钾含量处在80-160mg/kg低范围内；交换性镁丰富，平均为2.7cmol/kg；有效锌、有效铁和有效锰含量较高，平均分别为3.2mg/kg,101.7mg/kg和3.2mg/kg；水溶性氯和有效硼含量较低，平均分别为8.61mg/kg和0.4mg/kg。（2）嘉禾植烟土壤物理性状表明，土壤质地全部为轻壤土，适宜优质烤烟生产，浅灰黄泥、灰泥田和灰黄泥等土壤容重偏高(>1.4g/cm3)。（3）主要肥力因子与土壤物理指标相关分析表明，pH值与细砂粒和物理性黏粒含量呈显著相关，与粗砂粒和粗粉粒分别呈显著负相关和极显著负相关；有效磷含量与粗黏粒呈显著负相关；速效钾含量与细砂粒和黏粒呈显著和极显著正相关，与粗砂粒、粗粉粒、细粉粒和粗黏粒呈显著负相关。

Abstract:	Nutrient situation and physical character of 1375soil samples from Jiahe tobaccoarea,28 types soil were studied, as well as correlation between main fertility factors and physical character of soil were researched．The results indicated that (1) In Jiahe tobacco planting regions, light ash yellow mud, ash mud field, blue duck feces mud and ash yellow mud were about 50% of samples. Soils were slightly alkali. Average organic matter content was 4491g/kg, was relatively high. Soil available N content was rich, on average, was 17632mg/kg. Soil available P content was suitable, most of the samples were in the suitable range (10-20mg/kg).Most of the samples soil available K contents were in the low range (80-160mg/kg). Exchangeable Mg content was rich, on average, was 2.7cmol/kg. Available Zn, Fe and Mn content was relatively high, on average, were 3.2mg/kg,101.7mg/kg and 3.2mg/kg .Most of tobacco planting soil were B and Cl deficiency, water soluble Cl content was 8.61mg/kg and available B content was 0.4mg/kg.(2) Physical character of differently type soil in Jiahe tobacco area showed all the samples soil texture were light loam, were suitable to plant tobacco. Density of light ash yellow mud, ash mud field and ash yellow mud were relatively high, over 1.40g/cm3. (3) The correlation analysis between main fertility factors and physical character showed there was significant positive correlation between the pH value and Fine sand, Physical sticky grain, there was significant and extremely significant negative correlation between the pH value and coarse sand, thick powder. There was significant negative correlation between available P and physical sticky grain. There was significant and extremely significant positive correlation between available K and fine sand, sticky grain. There was significant negative correlation between available K and coarse sand, thick powder, fine powders, sticky grain.
