| 摘 要： | 不同光质的光照会对植物产生多种效应。本文研究了不同的农用塑料彩膜的光质特性,测定了10种彩膜及普通塑料膜(CK)的光谱透射率,从而算出它们的辐射通量的光谱密度,及其对可见光的平均透射率和可见光中各色光所占的百分比,为蔬莱的光质栽培提供了光学基础资料。

| Abstract: | With reference to differernt effects of various kinds of light on plant growth, many researches were done by using different kinds of artificial light sources. In our program attempt has been made to select special light quality from sunlight with colored film, in order to put this technique into vegetable cultivation. For this purpose, the characters for light transmitting from agricultural colored plastic films were studied and spectral transmittanee of 10 kinds of colored plastic films and commonused white plastic film (CK) were measured. Furthermore, we calculated their spectral radiant flux and the average transntittanee rate of visible light, the percentage of energy of all color light in visible light. The main object of this paper is to lag down the opticol basis for vegetable cultivation under different light quality. |
