【摘要】 农业的科研和生产活动与光密切相关,离不开光源。传统电光源不适宜应用于农业,半导体光源(LED)应用于现代农业具有无可比拟的优点和原理上的适用性。在农业生产和科研活动中采用LED光源,能够集中有效波长实施均衡近距离照射,达到高效能、低热负荷和紧凑空间的集约化植物生产,减少激素和农药等化学品的使用,实现绿色安全生产。综述了近年来LED光源在农业领域的研究与应用,内容包括:应用于植物设施栽培的LED特征,LED在植物工厂、工厂化植物育苗及设施园艺栽培中的应用。更多还原

【Abstract】 Light plays an important role in modern agriculture.The traditional light sources is not suitable for agriculture,while the light emitting diode(LED) when applied in modern agriculture has many advantages over the traditional light sources.This advantages includes that the effective spectrum for agriculture should be selected and concentrated for the use of biology,short distance between LED and biology should be adopted,high energy efficiency and low heat radiation should be received.The investigations and applications of LED in modern agriculture are summarized,which includes the characteristics of LED applied in agriculture,the applications and prospects of LED in plant tissue culture,protected horticulture.更多还原
