烟草氯素营养研究进展与展望

文章阐述了氯在烟草生长发育过程中的生理功能和吸收分配规律,总结了影响烟叶氯含量的主要因素以及氯在烟草中的遗传分析进展,指出国内烟叶氯含量分布存在不平衡现象,主要表现为南低北高,北方尤其黄淮烟区高氯问题仍然是影响烟叶工业可用性的限制因子,提出了精准农业在烟草氯营养中发展的方向,并指出氯营养在烟草分子遗传水平上研究尚少,关联分析技术是烟草氯营养现代研究中宏观与微观结合的重要手段,以此为烟草科学种植和提高烟叶质量提供参考。

Chlorine Nutrition on Tobacco Plants

This paper expounds the physiological function and the mechanism of absorption and distribution of chlorine. Recent researches on the relationship between chlorine and tobacco quality, the main factors influencing chlorine content and the genetic analysis of chlorine in tobacco were also reviewed. The distribution of chlorine content in domestic tobaccos exists imbalanced phenomenon, mainly manifested as south-low and north- high. The problem of high chlorine in the northern area, especially Huanghuai Tobacco Region remains the influence factor limiting tobacco industrial availability. This article presents that precision agriculture in the direction of the development of tobacco chlorine nutrition, and points out the research of chlorine nutrition in tobacco molecular genetic level were still few studies. Correlation analysis technology was an important means of macro and micro combination on the modern research of chlorine nutrition in tobacco. These conclusions and prospects were to provide reference for the cultivation of tobacco science and the improvement of the quality of tobacco leaf.
