1试验材料自然界中有一种具有转光性的物质,可以将太阳光谱中某些无效光源转化成对光合作用有效的蓝光、红光,从而可提高作物光合作用强度。将其加工成荧光转光助剂并添加入普通农膜中,就制成了生态转光膜。本试验所用生态转光膜为中国海洋大学光学光电子实验室研究制成。对照
MATERIALS OF THE TEST There is a substance in nature that has light-transitivity that can convert some of the ineffective light sources in the solar spectrum into blue and red light that are effective for photosynthesis and thus increase the crop photosynthesis intensity. Its processing into fluorescent light-transfer additives and added to the ordinary plastic sheeting, made of ecological transfer film. The ecological transfer film used in this experiment was made by the research institute of optics and optoelectronics of Ocean University of China. Control
