【摘要】 通过叶片的反射光谱测量来研究莴苣的光生态，采用在高分子树脂中分散进荧光助剂、着色剂来模拟栽培作物的光合作用之作用光谱。用这种光生态膜苫盖温室大棚进行蔬菜生产，产量提高了４４．６％ 。更多还原

【Abstract】 The photoecology of lettuce was studied with reflection spectrum by measring its leaf.Fluorescent auxiliary and colorant were dispersed into highmolecular resin in order to simulate action spectrum of photosynthesis.The results show that yields of vegetables have been increased 44 6% by using greenhouse built of the photoecology agricultural film.更多还原
