摘　　要：[目的]研究光伏幕墙对阳台微环境的影响以及在此微环境中西瓜的生长状况。[方法]以“甜王一号”西瓜品种为试材,栽培于阳台种植箱内,并对阳台微环境及西瓜质量和外观形态进行分析。[结果]在晴天条件下,室内阳台的温度为23.7~32.2℃,相对湿度为28.8%~49.2%,CO 2浓度为329.2~348.5 mg/L,光伏幕墙平均透光率为46.4%;在阴天条件下,室内阳台的温度为23.2~26.1℃,相对湿度为43.7%~52.1%,CO 2浓度为330.9~345.5 mg/L;09:00—11:30,西瓜叶片的叶绿素含量随着光照强度的增加而增加,当光照强度为44300 lx时,西瓜叶片的叶绿素含量达到最大值(42.5 mg/g)。测量了西瓜的质量和外观形态,最大单果质量为2.61 kg,纵横径分别为15.57和14.64 cm。[结论]在光伏幕墙的微环境下西瓜能正常生长并成功结出果实。[Objective]To study the effects of photovoltaic curtain wall on balcony microclimate and watermelon’s growth.[Method]“Tianwang No.1”watermelon variety was taken as test materials and cultivated in the planting box of balcony.And the balcony microclimate and the quality,appearance of watermelon were analyzed.[Result]Under sunny conditions,the temperature of indoor balcony was 23.7-32.2℃,the relative humidity was 28.8%-49.2%,the concentration of CO 2 was 329.2-348.5 mg/L,and the average transmittance of photovoltaic curtain wall was 46.4%.Under cloudy conditions,the temperature of indoor balcony was 23.2-26.1℃,the relative humidity was 43.7%-52.1%,and the concentration of CO 2 was 330.9-345.5 mg/L.From 09:00 to 11:30,the chlorophyll content in watermelon leaves increased with the rise of light intensity.When the light intensity was 44300 lx,the chlorophyll content in watermelon leaves reached the maximum(42.5 mg/g).The quality and appearance of watermelon were measured.The measurement results showed that the maximum single fruit mass was 2.61 kg,and the longitudinal and traverse diameter of watermelon fruit were 15.57 and 14.64 cm,respectively.[Conclusion]The watermelon could grow and fruit successfully under the microclimate of photovoltaic curtain wall.
