| 摘 要： | 以京研快菜为试材，设置遮阳网、遮阳网+ 外侧喷雾、遮阳网+ 内侧喷雾3 种降温处理，研究不同降温方式对日光温室环境指标的影响，以及对越夏快菜生长及品质的影响。结果表明：在夏季晴朗天气，3 种降温方式均能降低日光温室室内温度，其中遮阳网+ 内侧喷雾处理的降温效果最好；3 种降温处理均能提高快菜植株的净光合速率和气孔导度，遮阳网+ 内侧喷雾处理的快菜株高和叶片数显著高于仅遮阳网处理及对照，增设喷雾处理的快菜单株质量显著高于仅遮阳网处理且品质更好。

| Abstract: | Taking‘Jingyankuaicai’as test material，this paper set up 3 cooling treatments including screen-shading，screen-shading+external spray，and screen-shading+internal spray to study the effects of different cooling methods on environment index of solar greenhouses，and growth and quality of over summer Chinese cabbage．The results showed that in sunny weather of summer，all 3 cooling methods can reduce the indoor temperature of the solar greenhouse，and the screen-shading+internal spray treatment has the best cooling effect．All 3 cooling treatments could increase the net photosynthetic rate and stomatal conductance of Chinese cabbage plant．The plant height and leaf bade number of Chinese cabbage treated by screen-shading+internal spray were all higher and more than those of the contrast．The single plant weight of Chinese cabbage treated by spray were significantly increased than that only treated by screen-shading，and their quality is even better． |
