弱光条件下LED补光灯对苗期蔬菜生长的影响研究进展

Research Progress of Effect of LED on Vegetable Seedling under Low Photon Flux Intensity

随着现代农业体系的形成及发展,蔬菜育苗已成为较有前途的新兴产业而受到广大关注。如何在弱光条件下大规模生产高品质、低成本的优质种苗已成为近年来育苗产业研究的重点。从光质、光照强度和光周期3个方面叙述弱光条件下LED补光灯对苗期蔬菜生长发育影响的研究进展,并指出该方面研究存在的问题、今后的研究思路及可能的研究方向,以供研究人员参考。

With the rapid development of modern agriculture,vegetable seedling has become a dynamic emerging industry received widespread attention.How to produce large-scale,high-quality and low-cost seedlings inweak and sparse light stresses has become the focus of research in the nursery industry.The research progress on effect of LED on vegetable seedling culture was described from light quality,light intensity and photoperiod three fields,and the problems in this area and future research ideas and possible directions for the research departments were pointed out.It can provide reference for researchers.
