| 摘要：为了探讨光伏温室光伏板组件布置密度对温室内小白菜生长等的影响，本文比较温室覆盖不同光伏组件密度下室内外环境特性，以及其对小白菜生长、光合作用、产量和品质的影响。结果表明，不同密度光伏板覆盖处理对温室内的环境因子影响较小；33%光伏板覆盖处理对小白菜生长的影响相对较小，光合作用气体交换参数及叶绿素含量的影响亦不显著；50%光伏板覆盖密度处理下的小白菜可溶性糖含量下降75.10%，而硝酸盐含量提高了34.15%；33%光伏板覆盖处理对小白菜有机酸、可溶性蛋白、可溶性糖、硝酸盐、VC 含量影响不显著；50%、33%光伏板覆盖密度处理小白菜产量分别降低了31.48%、13.43%。因此，50%光伏板覆盖密度的温室不推荐用于小白菜的生产，而33%光伏板覆盖密度的温室可以用于小白菜的生产。25683 毕业论文关键词：光伏温室；小白菜；生长；光合作用；产量；品质 Effects of photovoltaic panels layout density on growth, photosynthesis and quality of Chinese Cabbage (Brassica Chinensis NHCC.） Abstract:This study aimed to explore the practical application of photovoltaic panels layout density in Chinese Cabbage (Brassica Chinensis NHCC.) cultivation.In this experiment,we compared the indoor and outdoor environmental factors of greenhouse with different photovoltaic panels layout density and their effects on growth,photosynthesis and quality of Chinese Cabbage (Brassica Chinensis NHCC.).The result showed that The results show that different density of photovoltaic panels covered with small environmental factors in the greenhouse effect; 33% photovoltaic panels covering the effect on the growth of cabbage is relatively small, affect the chlorophyll content photosynthetic gas exchange parameters and is not significant; 50% photovoltaic panels and the coverage density of Chinese cabbage soluble sugar content decreased by 75.10%, while nitrate salt content increased by 34.15%; 33% photovoltaic panels cover treatment was not significant on Chinese cabbage organic acid, soluble protein, soluble sugar, nitrate, VC content; 50%, 33% photovoltaic panels covering density of cabbage yield were decreased by 31.48%, 13.43%. As a result, the 50% solar panel density greenhouse is not recommended for the production of pakchoi, while the 33% photovoltaic panel density greenhouse can be used for the production of Pakchoi.
