根系分泌物在水稻氮素吸收利用中的作用机制及氮肥调控研究进展
Research Progress on the Mechanism of Root Exudates in Nitrogen Absorption and Utilization of Rice and the Regulation of Nitrogen Fertilizer
摘要
Abstract
Nitrogen is a key nutrient element for plant growth and development,which is mainly absorbed by plant roots and plays a vital physiological role in various life processes.Root exudates are chemical substances secreted or exuded by roots into the growth medium during nutrient metabolism.They significantly effect the process of nitrogen absorption and utilization in rice.In this paper,the types,functions and production pathways of rice root exudates were reviewed,the roles of root exudates in nitrogen absorption and utilization of rice were analyzed,and the effects of nitrogen fertilizer regulation on root exudates were discussed.Furthermore,this paper summarized the new ideas of nitrogen fertilizer reduction and efficiency improvement oriented by"secretion",pointed out the problems existing in the current research,and looked forward to the future research direction,aiming to provide theoretical basis and practical guidance for formulating reasonable nitrogen fertilizer management strategies and realizing high yield of rice.关键词
