摘　　要：在山东沂南光伏电站设置试验,研究露地光伏-丹参生产模式下的光照变化,以及这种变化对丹参生长的影响。结果表明:利用天文学方法能够准确计算出光伏板阵列行间的遮荫状态;对于东西方向排列的光伏板的行间,在一天当中既受到北侧光伏板的遮荫,也受到来自南侧光伏板的遮荫,其遮荫程度随季节变化而不同;距离南侧较近的丹参垄受到遮荫影响最大,整个生育期日照时数仅有400 h,约为对照(无遮荫)的38%,距离北侧光伏板最近的丹参垄受到遮荫影响最小,日照时数约800 h,为对照的77%;遮荫对丹参的株高、净光合速率、SPAD值、根部性状均有显著影响,日照时数400 h和610 h处理的产量仅为对照的50%和69%。综合评价,日照时数达到对照70%以上(即日照时数720 h以上),对丹参生长的影响不显著。Different shading treatments were conducted in the Shandong Yinan Photovohaic Power Station to study the light change under the production mode of photovohaic and Danshen （Salvia mihiorrhiza Bge. ） cultivated in open field, and the effect of this change on the growth of Danshen. The results showed ： the shad- ing state between the rows of the voltage - plate array could be calculated accurately by using astronomy meth- od ; for the inter - row of photovohaic panels arranged in the east - west direction, they were shaded not only by the north side but also by the south side of the light panel during one day, and the degree of shading varies with the season ; the Danshen ridge, which was close to the south side of the photovohaic plates, was the most affected by shading, and the sunshine hours during the entire growth period had only 400 hours, which was a- bout 38% of the contM （without shading） , on the other hand, the Danshen ridge, which was close to the north side of the photovohaic plates, was shaded minimally, and the sunshine hours was about 800 hours,which was about 77% of the control. Shading had a significant impact on plant height, net photosynthetic rate, SPAD value, and toot traits of Danshen. The yield of treatments of 400 hours and 610 hours of sunshine was only 50% and 69% of the control. The effect on the growth of Danshen was not significant when sunshine hours reached more than 70% of the control（ie, 720 hours or more）.
