【摘要】 在天然和人工陆地生态系统中,植物如何从土壤中快速有效地获取养分是决定其竞争力和生产力的关键,在该过程中植物根系的结构发育及其与环境之间的相互作用尤为重要。随着研究的不断深入,学者们发现,植物根系结构很大程度上受到土壤理化性质的调控,同时,根系生理过程也会调节土壤理化性质尤其是养分的有效性。对植物养分限制下的生理过程研究表明,不同的养分因子对植物根系发育的影响差异显著。对陆生植物的根系发育及其受到养分调控的现状进行了简要阐述,为更好地理解根系尤其是植物根毛结构的功能与意义做一定铺垫。更多还原

【Abstract】 In natural and artificial terrestrial ecosystems, how plants gets nutrients from soil in the fast and effective way are the key decides their competitiveness and productivity, and the developments of roots structures and the interactions with the environment are very important in these process. With constantly to in-depth research, scholars found that plant root structure greatly influenced by soil physico-chemical properties of regulation, while soil physico-chemical properties especially nutrient effectiveness also were changed by root physiological process of regulation. Researches on physiological processes of nutrient limitation especially particular nutrient factor show significant and different effects on plant root development. This paper briefly expounds the present situation of terrestrial plants and root growth by nutrient regulation, which will do some groundwork to better understand the root system especially the function and significance of root hair structure.更多还原
