一种基于LED脉冲光增加蔬果营养成分的方法
技术领域
本发明涉及一种光信号增加蔬果营养成分的方法，尤其涉及一种基于LED脉冲光增加蔬果营养成分的方法。
背景技术
我国是一个农业大国，农业在我国有着重要的地位，在我国，农业的现状在极大程度上依然按传统方式，高成本、低效率，投入较高，产值和质量较低，这些特征使得农业成为国民经济中亟待发展的一环。利用科学的植物补光方法提高农产品的产量和质量是解决农业现状的一个有效途径，光合作用是植物生长、合成有机物质的关键环节，光照不仅会影响植物的光合作用，同时，不同波长的光可以极大的改变植物的特性，通过改变照射光线的波长，进而改变蔬菜和水果的味道以及增加其营养成分的含量，在远红外线的照射下，植物会大量释放一种名为'2-苯乙醇'的挥发性物质，而这种物质恰好是改善蔬菜水果味道的关键，可以通过改变蔬菜水果周围的光照环境来使它们的味道变得更好，同时也能通过改变光线类型来提高它们的抗氧化性、改善它们的外观以及增加其营养成分的含量。
发明内容
本发明要解决的主要技术问题是提供一种基于LED脉冲光增加蔬果营养成分的方法，采用光谱控制器调控LED发光体激发光波的波长，以及控制LED发光体闪烁的频率，可有效增加蔬果的营养成分以及改善蔬果的味道。

进一步的，所述LED发光体发出的远红外线的波长为3000nm-50,000nm。
更进一步的，所述LED发光体发出的红光波长为600nm-700nm，蓝光波长为400nm-500nm。

本发明与现有技术相比，具有如下有益效果：
本发明新型LED基于LED脉冲光增加蔬果营养成分的方法，采用光谱控制器调控LED发光体，产生各种有规律的脉冲式周期光谱光信号，可以有效增加蔬果的营养成分；另一方面，通过这种光谱的设置及合理的照射周期，蔬果的口感和味道也比一般种植的蔬果要好很多。
具体实施方式
下面结合实施例对本发明的具体方法做进一步详细的描述，但本发明的实施方式不限于此。
实施例1
本发明基于LED脉冲光增加蔬果营养成分的方法，采用光谱控制器调控LED发光体激发光波的波长，以及控制LED发光体闪烁的频率；LED发光体由光谱控制器调控的发光顺序为：红光、橙光、蓝光、紫光（0.01秒）→远红外线（0.01秒）→红光、橙光（0.01秒）→蓝光、紫光（0.01秒）→红光、橙光、蓝光、紫光（0.01秒），按此顺序变化产生不同光线的交叉、组合形式，在扫描一个周期以后全部光熄灭（0.01秒），产生一个脉冲光谱周期后，再重复上述脉冲扫描过程，LED发光体按照上述顺序发出红、橙、蓝、紫光信号及远红外线组合光信号照射植物，LED发光体发出的红光波长为600nm-700nm，蓝光波长为400nm-500nm，优选的，LED发光体发出的红光波长为638.12nm，蓝光波长为467.75nm，此外，采用波段为3000nm-50,000nm的远红外线照射，可以促使植物大量释放一种'2-苯乙醇'的挥发性物质，有效改善了蔬果的味道和口感，促进各种有益物质的合成积累，有效增加蔬果的营养成分，通过这种光谱的设置及合理的照射周期，蔬果的味道和口感比一般种植的蔬果要好很多。
本发明的实际试验例：
本发明的试验方法：参考中华人民共和国农业行业标准NY/T428-2000、中华人民共和国农业行业标准：（无公害食品蔬菜）NY5193-2002及相关蔬菜水果检测、包装、运输及贮藏的保鲜标准或方法。
