| 摘 要： | 为揭示光伏电板布设对植物生长的影响，选取2016年人工种植的位于光伏电板板前沿、板后沿、板下三种典型部位的沙打旺(Astragalus adsurgens)为研究对象，对其株高、叶片性状及茎叶养分进行了测定。结果表明：①沙打旺株高均呈板下>板前沿>板后沿>对照，最大值板下分别比对照增加了3070%、8750%、9997%；②板下的比叶面积由18845 cm2·g-1增加至22024 cm2·g-1，而对照的比叶面积由13886 cm2·g-1减少至10214 cm2·g-1，光伏电板的布设使得沙打旺叶片表现出逐渐变长变薄变大的适应趋势；③光伏电板周边位置沙打旺的N含量与粗蛋白含量均大于对照，而P含量则在板下有明显增加，由008%增加至019%，说明光伏电板可以促进N、粗蛋白及P含量积累；④各位置地上生物量鲜重显著高于对照。因此，光伏电板的布设可以显著促进沙打旺更好地生长发育。

| Abstract: | In order to reveal the effect of photovoltaic panel arrangement on plant growth, this study selected Astragalus adsurgens as subject which were planted in 2016 at three typical parts such as the plate front edge, the plate back edge, and under the plate, and determined its plant height, leaf characters and stem and leaf nutrients. The results showed that: ① The plant height of Astragalus adsurgens was the under plate>the plate front edge>the plate back edge>the control group, and the maximal value which was the under plate was increased by 3070%、8750%、9997% than the control group, respectively. ② The specific leaf area of the under plate was increased from 18845 cm2·g-1 to 22024 cm2·g-1,but the specific leaf area of the control group was decreased from 13886 cm2·g-1 to 10214 cm2·g-1,the layout of photovoltaic panels made the leaves of Astragalus adsurgens grow longer and thinner and bigger. ③The N content and crude protein content of Astragalus adsurgens around the photovoltaic board were higher than the control group, while the P content increased significantly of the under plate from 008% to 019%, it could be seen that the photovoltaic panels were beneficial to the accumulation of N, crude protein and P. ④The fresh weight of aboveground biomass at each position was significantly higher than that of the control group. Therefore, the placement of photovoltaic panels could significantly promote the better growth and development of Astragalus adsurgens. |
