摘要
为助推光伏技术在我国农业高质量发展中的转型应用,以60%遮阴的普通日光温室为对照,研究60%遮光率的新型碲化镉光伏日光温室内夏季空气温度、空气湿度和光照强度的变化,以及对生菜生长、光合特性和品质的影响。结果表明,与60%遮阴的普通日光温室相比,新型碲化镉光伏日光温室能显著降低进入温室的太阳辐射能量和太阳光线的透过率,温室内光照强度降低46%以上,空气温度降低3℃以上,空气湿度增加30%以上,同时也能显著提高生菜的叶绿素含量、净光合速率、蒸腾速率、气孔导度并显著降低胞间CO_(2)浓度。与60%遮阴的普通日光温室相比,新型碲化镉光伏日光温室定植后第28天的生菜各生长指标均显著提高,株高提高了31%以上,叶片数增加了19%以上,鲜质量和干质量分别提高了15%和32%以上;各营养品质指标也显著提高,可溶性固形物、可溶性糖、可溶性蛋白和维生素C含量分别提高了0.43百分点、0.04百分点、25%和72%。此外,2024年6-9月期间的月平均发电量为2076.08 kWh。综上可知,新型碲化镉光伏日光温室在夏季生菜种植的应用中展现出了显著的经济效益,为光伏日光温室农光互补模式应用提供了重要的理论依据。
To promote the transformative application of photovoltaic technology in the high-quality development of agriculture in China,this study compared a conventional solar greenhouse with 60%shading as a control group with a novel CdTe photovoltaic solar greenhouse with 60%shading.The study investigated changes in summer air temperature,air humidity,and light intensity,as well as their impacts on lettuce growth,photosynthetic characteristics,and quality.The results indicate that compared to the conventional solar greenhouse with 60%shading,the novel CdTe photovoltaic solar greenhouse significantly reduced the amount of solar radiation entering the greenhouse and the transmittance of sunlight.The light intensity inside the greenhouse decreased by over 46%,the air temperature dropped by more than 3℃,and the air humidity increased by over 30%.The photovoltaic solar greenhouse also significantly enhanced the chlorophyll content,net photosynthetic rate,transpiration rate,and stomatal conductance of lettuce,while significantly reducing the intercellular CO_(2) concentration.Compared to the conventional solar greenhouse with 60%shading,the novel CdTe photovoltaic solar greenhouse showed significantly improved all growth indicators of lettuce for 28 days after planting.The plant height increased by over 31%,the number of leaves rose by more than 19%,and the fresh and dry mass increased by 15%and 32%,respectively;all nutritional quality indicators also showed significant improvement,with soluble solids,soluble sugars,soluble proteins,and vitamin C content increasing by 0.43 percentage points,0.04 percentage points,25%,and 72%,respectively.Additionally,the average monthly power generation from June to September 2024 was 2,076.08 kWh.In conclusion,the novel CdTe photovoltaic solar greenhouse demonstrates significant economic benefits in summer lettuce cultivation,providing crucial theoretical support for the application of the agricultural-photovoltaic complementary model in photovoltaic solar greenhouses.
