黑土中NH4+、K+、Ca2+、Mg2+对烤烟中钾含量的影响
Effect of NH4+、K+、Ca2+、Mg2+ in black soil on potassium content in flue-cured tobacco
【摘要】 采用框栽田间模拟试验方法对哈尔滨黑土中不同浓度养分离子对烟叶中钾含量的影响进行了研究。结果表明 ,烟叶中钾含量与土壤中 NH4 +浓度无明显相关性 ,而与土壤中 K+浓度呈显著正相关 γ=0 .935* ,土壤中 Ca2 +、Mg2 +浓度增加使烟叶中钾含量有所降低
【Abstract】 Effect of Different nutrition content on potassium content in flue cured tobacco was studied with fram culture experiment method in Harbin black soil.The result shows that there has striking positive correlation between potassium content in flue cured tobacco leaf and K + content in soil (r=0 935 *),but NH 4 + content in soil has no effect on potassium content in flue cured tobacco leaf.With Ca 2+ and Mg 2+ increasing in soil,the potassium content in tobacco leaf somewhat descends. $$$$
