【摘要】 太阳辐射光谱的主要范围在150nm～4000nm之间。不同波长的光的物理性质不同,对果树产生的光化学反应以及对果树生长发育的影响也不同。紫外线主要产生损伤作用,可见光主要是促进和调节作用,红外线主要是热效应,给果树提供能量。更多还原

【Abstract】 The main range of sunshine spectrum is between 150 run and 4000 nm;Different light has dif- ferent physical characteristics,and therefore the influence of light-chemical reaction on the growth of fruit trees is also different;Generally,ultraviolet radiation will damage fruit trees,visible light has an effect of improving and regulating fruit trees,and infrared ray has a heat effect and can provide heat for fruit trees.更多还原
