西红柿的光生态研究

Studies on the Photoecology of the Tomato

采用叶片的反射光谱测量来研究西红柿的光生态。西红柿叶片在４５０ｎｍ处、６８０ｎｍ处各有一条带宽为１２０ｎｍ的吸收带，这说明蓝、红光能够促进西红柿的生长。往聚乙烯树脂中添加荧光助剂、着色剂模拟西红柿作用光谱制成农膜。用这种农膜苫盖温室大棚进行西红柿生产。通过产量调查来进一步认证西红柿的光生态。

The photoecology of the tomato was stuied with reflection spectrum of blades.There are a blue(at 450nm)and a red (at 680nm)absorption band in the blades of the tomato.The width of each band is 120nm respectively.It shows that the blue and red adsorption can help the growing for tomato.The coloring agent and fluorescent materials were doped into the polystyrene film to simulate the function spectrum of tomato.Growing the tomato was covered with this kind of agricultural film.The photoecology of the tomato has proved futher by the research for output.
