促進(jìn)煙草根系發(fā)育研究進(jìn)展

摘要 根系是煙株吸收水分和養(yǎng)分的重要器官，根系的生長(zhǎng)發(fā)育以及活力直接影響著煙株地上部的生長(zhǎng)發(fā)育、營(yíng)養(yǎng)狀況與煙葉品質(zhì)。從煙草根系的組成、生理功能、影響根系生長(zhǎng)發(fā)育的因素以及促根措施4個(gè)方面入手，總結(jié)了煙草根系研究的最新進(jìn)展，并對(duì)今后的研究提出了展望，旨在為烤煙根系研究和優(yōu)質(zhì)煙葉生產(chǎn)提供參考。

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.
