中文摘要：
以普通白菜品种苏州青为试验材料，采用穴盘基质栽培方法，研究温室覆盖不同光伏组件密度对普通白菜生长、光合作用、产量及品质的影响。结果表明：50%光伏板覆盖处理的普通白菜株高、叶片数和叶面积比对照显著降低了27.34%、12.50%和22.64%，而33%光伏板覆盖处理对普通白菜生长的影响相对较小；除可溶性糖含量和可溶性蛋白含量显著下降外，光伏板覆盖（33%和50%）处理对普通白菜有机酸、硝酸盐、VC含量影响不显著，对植株气体交换参数及叶绿素a、叶绿素b含量的影响亦不显著；50%光伏板覆盖处理显著降低了普通白菜单株质量和单个穴盘产量，而33%光伏板覆盖处理与对照差异不显著。综上，33%光伏板覆盖温室可用于普通白菜栽培生产。
英文摘要：
Taking pakchoi〔Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee〕cultivar‘Suzhouqing’as experiment material,this paper studied the effects of different photovoltaic panel layout density on growth,photosynthesis,yield and quality of pakchoi by plug substrate culture method.The result showed that photovoltaic greenhouse with50%panel cover could significantly decrease the plant height,leaf number and leaf areas of pakchoi by27.34%,12.50%and22.64%,respectively.While with33%photovoltaic panel cover,there were relatively smaller influence on the growth of pakchoi.Besides the significant decrease of soluble sugar and soluble protein contents,there were no significant effects on organic acid,nitrate,VC content by treatments of33%or50%photovoltaic panel cover.There were neither significant influences on plant gas exchange and contents of chlorophyll aand chlorophyll b.The weight per plant and the yield per plug of pakchoi were decreased by photovoltaic greenhouse with50%panel cover,but no remarkable differences between treatment with33%photovoltaic panel cover and the CK.These results suggest that greenhouse with33%photovoltaic panel cover could be used to produce pakchoi.
