摘要
以湖南烟区 30 0多个土样和 2 5 6个烟样为材料 ,研究了烤烟叶片硝酸盐和亚硝酸盐含量与土壤养分的关系。结果表明 :烟叶中硝态氮含量因等级不同而异 ,呈现出C3F >B2 F >X2 F的趋势 ;不同等级烟叶 (亚 )硝酸盐含量与土壤有机质、全氮、碱解氮、铵态氮含量的相关系数均达到极显著水平 ,与土壤全磷、全钾、pH值、有效磷、有效钾及其他中、微量元素的相关则未达到显著水平。
More than 300 soil samples and 256 flue-cured tobacco leaf samples from Hunan tobacco-growing areas were analyzed to study the relationship between soil nutrients and nitrate and nitrite content in flue-cured tobacco leaf.The results indicated that nitrate nitrogen content in flue-cured tobacco was different for different grade leaf, which showed the trend of C 3F>B 2F>X 2F.The correlation coefficients of contents of nitrate and nitrite of tobacco leaf with different grade were significant at 1% level with contents of organic matter, total N, hydrolytic N and ammonia N, and were not significant at 5% level with contents of total P, total K, pH value, available P, available K, and other nutrient elements.
