摘要
植物的生长需要适宜的光照环境,然而在自然条件下,植物生长面临阳光、温度、水分等诸多不可控问题.为解决传统农业种植中气温光照不稳定的问题,人们开始发展工厂种植,其中植物的工厂种植核心就是人工光源.近年来植物补光技术被越来越广泛地应用,光照对植物生长的影响及人工补光技术的研究也越来越多.本文介绍了LED植物灯的发展历程、现代LED光源作为植物工厂人工光源的优势、LED植物补光灯发光原理、及部分文中所涉及的光学参数;并总结了Eu2+、Eu3+、Mn4+、Cr3+、多离子共掺杂等荧光粉在植物补光技术中的研究现状.最后对以上不同荧光粉在植物补光技术中的优缺点进行了分析,对LED荧光粉在植物补光领域的发展前景进行了展望,为相关科研人员或机构提供了一些有技术价值的参考.
Abstract
Plants require suitable lighting conditions for growth.However,in natural settings,plant growth is subjected to numerous uncontrollable factors such as sunlight,temperature,water availability,and others.To address the issue of unstable temperature and lighting in traditional agricultural practices,people have begun to develop factory farming.The core of factory farming for plants lies in artificial lighting sources.In recent years,plant supplemental lighting technology has been increasingly applied,and there has been a growing amount of research on the effects of light on plant growth and artificial supplemental lighting techniques.This article introduces the development history of LED plant lights,the advantages of modern LED light sources as artificial light sources in plant factories,the emission principle of LED supplemental lights,and some optical parameters mentioned in the article.It also summarizes the current research status of phosphors such as Eu2+,Eu3+,Mn4+,Cr3+,and multi-ions co-doping in plant supplemental lighting technology.Finally,an analysis of the advantages and disadvantages of the different phosphors in plant supplemental lighting technology is provided.The potential development prospects of LED phosphors in the field of plant supplemental lighting are also discussed.This offers valuable technical references for relevant researchers or institutions.
