磷素是烟草生命活动过程中不可缺少的重要营养元素之一,它不仅直接参于烟草体内碳水化合物和含氮物质的合成、运输和贮存等重要生理代谢活动,同时还具有形成多种酶类和磷酸酯等重要物质,增加烟叶香味,提高品质的作用。在不同生态环境和不同栽培条件下烟草对磷肥的吸收作用和分配特点的研究尚不多,然而这正是烟草生产中迫切需要研究解决的问题。 Phosphorus is one of the indispensable and important nutrition elements in the life and activity of tobacco. It not only directly participates in the important physiological and metabolic activities of synthesis, transport and storage of carbohydrates and nitrogenous substances in tobacco, but also has the functions of forming many kinds of enzymes And phosphate and other important substances, increase the flavor of tobacco, improve the quality of the role. However, there is not much research on the absorption and distribution characteristics of P in different ecological environments and different cultivation conditions. However, this is an urgent problem that needs to be studied and solved in tobacco production.
