皖南烟区植烟土壤养分状况分析
|
摘要
[目的]研究皖南烟区土壤养分状况。[方法]选取皖南烟区2个市4个产烟县(区)中的黄渡、城区、芜湖、南陵、泾县5个烟站所覆盖的30个种烟乡镇,共采集土样139个进行理化性状检测。[结果]植烟土壤平均pH黄渡5.87、城区5.62、芜湖5.77、南陵5.76、郎溪5.44、泾县5.61;植烟土壤平均有机质含量黄渡22.80 g/kg、城区26.23 g/kg、芜湖27.19 g/kg、南陵31.42 g/kg、郎溪22.65 g/kg、泾县30.72 g/kg;总氮含量为1.00～2.00 g/kg,>2.00 g/kg的土壤占41.18%,碱解氮含量主要在120mg/kg以上。[结论]皖南烟区植烟土壤以酸性至微酸性为主,基本处于最适宜范围之内,土壤有机质含量较丰富,土壤总氮和碱解氮含量偏高,土壤速效钾含量偏低,不同烟站区域之间肥力特征差异较大。
[Objective]To understand the status of tobacco-planting soil in Wannan Area.[Method]139 soil samples were collected and analyzed from two cities of Wannan Anhui Tobacco District and 30 tobacco-producing townships covered by five tobacco stations in four tobacco-producing counties(districts), Huangdu, Chengqu, Wuhu, Nanling and Jingxian.[Result]The average soil pH was 5.87 in Huangdu, 5.62 in Chenqu, 5.77 in Wuhu, 5.76 in Nanling, 5.44 in Langxi and 5.61 in Jingxian;the average organic matter content in tobacco-growing soils was 22.80 g/kg in Huangdu, 26.23 g/kg in Chenqu, 27.19 g/kg in Wuhu, 31.42 g/kg in Nanling, 22.65 g/kg in Langxi and 30.72 g/kg in Jingxian;the mainly distribution range of total nitrogen content was 1.00-2.00 g/kg, the soil total nitrogen of 41.18% was 2.00 g/kg, the main distribution range of alkali-hydrolyzed nitrogen content was more than 120 mg/kg.[Conclusion]Soils grown in tobacco-planting areas in Wannan Area are mainly acidic to slightly acidic, they are basically within the optimum range, soil organic matter is abundant.The soil of total nitrogen and alkaline hydrolyzable nitrogen content is higher, available potassium content is low, the soil fertility characteristics had greater differences among different tobacco stations.
