土壤质地对烤烟叶片类胡萝卜素及叶绿素的影响

摘要

The effects of soil texture on the carotenoid, chlorophyll a and chlorophyll b content in the leaf of flue - cured tobacco in Luzhou city of Sichuan province were analyzed. In flint soil, the content of carotenoid, chlorophyll a and chlorophyll b in tobacco leaf was the highest in general, and the quality of tobacco leaf was the best, which was followed by that in yellow soil and in paddy soil. There was significant difference in carotenoid and chlorophyll content among different soil textures. Therefore, the Dint soil was beneficial to the quality formation of tobacco leaf.%研究了四川泸州不同质地土壤对烤烟叶片类胡萝卜素、叶绿素a、叶绿素b含量的影响,结果表明:火石土烟株烟叶的类胡萝卜素、叶绿素a、叶绿素b含量总体上最佳,烟叶品质最高,其次是黄壤土和水稻土,且差异显著,因此,火石土有利于烟株烟叶品质的形成.
