摘要
Abstract
The greenhouse covered with direct-light thin film was used as the control, and the effects of diffuse light on the plant growth indexes, leaf biochemical indexes and fruit yield of tomato at different planting densities in the greenhouse covered with diffuse-light thin film were studied. The experimental results indicated that: in comparison with direct light, diffuse light could enhance the photosynthesis in middle and lower leaves of tomato plants, improve their growth characters, and increase the fruit yield of low-density and high-density tomato plants by 5.5％ and 12.9％, respectively. Thus, in the greenhouse covered with diffuse-light thin film, the planting density of tomato could be increased appropriately, in order to enhance the sunlight use effi?ciency.关键词
