摘  要：
为探明重庆主要植烟土壤的肥力状况,以便为土壤改良和施肥决策提供理论依据,对10个县植烟土壤的p H值及有机质、碱解氮、速效磷、速效钾、水溶性氯、交换性钙和镁等含量进行了研究。结果表明,研究区50%以上植烟土壤酸化严重,黔江、丰都、石柱县有60%以上植烟土壤p H值小于5.5;有机质和速效磷含量总体适宜;碱解氮含量偏高,有95.71%的植烟土壤氮素供应过剩;速效钾含量总体适宜,仅33.10%的土样含量偏低;水溶性氯含量总体偏低,仅33.99%的土样适宜烤烟种植;交换性钙含量中等偏低,交换性镁含量中等偏高。因此,在烟叶生产中要加强酸化土壤治理,严格控制氮肥,适量补充磷、钾、镁肥,增施氯、钙素肥料。

摘  要：
In order to explore the soil fertility conditions in Chongqing tobacco growing areas and provide theoretical basis for soil improvement and fertilization strategy,the p H value,organic matter,available N,available P,available K,water-soluble Cl,and exchangeable Ca and Mg contents of soil in 10 counties in Chongqing tobacco growing areas were analyzed. The results showed that above 50% of the soil in the studied area were of acidity,and the proportion of p H value which was less than 5. 5 was more than 60%in the Qianjiang,Fengdu and Shizhu county. The contents of organic matter and available P were medium.The content of available N was generally high,available N content of 95. 71% soil samples was excess.The content of available K was generally appropriate,the available K content of 33. 10% soil samples was low. The content of water-soluble Cl was low,the proportion of soil samples whose water-soluble Cl content was suitable to plant tobacco was 33. 99%. The content of exchangeable Ca was little lower than medium,and the content of exchangeable Mg was little higher than medium. Therefore,the suggestions were put forward,such as strengthening the soil acidification in Chongqing tobacco growing areas,controlling N fertilizer application amount,supplementing P,K and Mg in moderation,and adding Cl and Ca fertilizers.
