Vegetable plantation method and LED light source

The invention provides a vegetable plantation method. An LED light source is used to irradiate leaves of vegetables, light emitted by the LED light source including blue light and red light, and the proportion of light energy of blue light to light energy of red light is 0.7-1.5:1. Under irradiation in the light energy proportion, leafy vegetables grows rapidly and vigorously, the production period can be shortened, and the output is increased. The invention also provides the LED light source, the LED light source comprises a glue light chip and mixing fluorescent powder fixed to the blue light chip, the mixing fluorescent powder comprises red fluorescent powder and green fluorescent powder in the weight ratio of 1:1-1.5, and the LED light source can be applied to vegetable plantation. 本发明提供种蔬菜种植方法，采用LED灯光源照射蔬菜叶面，所述LED灯光源的发射光包括蓝光与红光，其中蓝光与红光的光能量比例为0.7-1.5：1。在此光能量比例照射下的叶菜生长迅速、长势良好，可缩短生长周期，增加产量。本发明还提供种LED灯光源，所述LED灯光源包括蓝光芯片以及固定于所述蓝光芯片上的混合荧光粉，所述混合荧光粉包括红色荧光粉、绿色荧光粉按重量比为1：1-1.5比例混合，可用于蔬菜种植中，所述LED灯光源照射的叶菜生长迅速、长势良好，可缩短
