| 摘 要： | 2008-2010年采集了龙陵烟区有代表性的植烟土壤样品170个,进行了土壤的理化性状分析。结果表明:龙陵烟区植烟土壤总体偏酸性,平均为5.68,85.88%的植烟土壤偏酸性;土壤有机质和速效氮含量处于中等-丰富,有机质平均30.2g/kg,碱解氮平均111.90mg/kg,45.29%的土壤有机质含量30mg/kg;土壤速效磷含量平均17.70mg/kg,有74.71%的植烟土壤速效磷20mg/kg;植烟土壤速效钾含量平均139.41mg/kg,速效钾含量150 mg/kg的植烟土壤占31.76%;土壤有效镁含量平均为202.52mg/kg,处于匮乏-中等水平;有效锌含量平均为1.88mg/kg,总体较丰富;有效硼含量平均为0.32mg/kg,处于极缺乏水平。龙陵烟区烤烟生产上应因地制宜,加强平衡施肥技术,严格控制氮肥施用量,增施磷肥和钾肥;同时注意补充镁肥、硼肥等中微量元素。

| Abstract: | The nutrients in 170 soil samples collected from tobacco-growing areas in Longling of Yunnan provinces were analyzed.The results showed that most soils were acidic soil,the average soil was 5.68,accounting for 85.88%;The high soil organic matters and available nitrogen were found.the average contents of soils organic matters was 30.2g/kg,alkalihy drolyzable N was 111.90mg/kg,45.29% of the soil organic matter content of30mg/kg;average content of soil available 17.70mg/kg,with 74.71% available P in soil of tobacco area 20mg/kg;average tobacco soil K contents was 139.41mg/kg,soil K content150 mg / kg of tobacco soil accounted for 31.76%;average Mg content of soil was 202.52mg/kg,at scared-the middle level;available Zn content was 1.88mg/kg,generally richer;effective B content was 0.32mg/kg,at the very lack of standards.Longling tobacco area should be adapt to local conditions,strengthen the balanced fertilization technology,control of N,increasing P and K were recommended.Also note added magnesium,boron and other trace elements. |
