摘　　要：以直射光薄膜温室为对照,在覆盖散射光薄膜的温室中研究了散射光对不同种植密度番茄植株生长指标、叶片生化指标及果实产量的影响。试验结果表明:与直射光相比,散射光能增强番茄中、下部叶片的光合作用能力,改善番茄植株的生长性状,提高果实产量,低、高密度种植区的番茄产量分别提高了5.5%和12.9%。说明在覆盖散射光薄膜的温室中可以适当增加番茄的种植密度,以提高对日光的利用效率。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 efficiency.
