促进烟草根系发育研究进展

摘要 根系是烟株吸收水分和养分的重要器官，根系的生长发育以及活力直接影响着烟株地上部的生长发育、营养状况与烟叶品质。从烟草根系的组成、生理功能、影响根系生长发育的因素以及促根措施4个方面入手，总结了烟草根系研究的最新进展，并对今后的研究提出了展望，旨在为烤烟根系研究和优质烟叶生产提供参考。

Research Progress of Promoting Tobacco Root Development

SHEN Zheng1，XU Jun1，LI Xue-qin2 et al

Abstract The root system is an important organ for tobacco plants to absorb water and nutrients.The growth，development and vitality of the root system directly affect the growth and development and  nutritional status in the aboveground parts and leaf quality of tobacco plants.This paper summarized the latest progress of tobacco root research from four aspects： root composition，physiological function，factors affecting root growth and development and measures promoting root growth.We also put forward prospects for future research，aiming to provide reference for flue-cured tobacco root research and high-quality tobacco leaf production.
