Experimental Design:To compare and Contrast the effects of powerlines and thicket on growth of goldenrods

We performed a comparitive study on golenrods on a plot and see how and by what magnitude are they affected by powerlines or thickets.WE observed that the powerlines had longer goldenrods as they affected plants in measn of indirect measure through EMF while thicketss competed in all possible ways with golden rodsWE simply just used quadrats,thermometres and metre stick to replicte the measurements.To hve complete randomization we chose random places every working day with just subject of influence and blocking other affecting factors.Our results wer stastically signficant and our predictions came true本研究在样地内开展一枝黄花（goldenrod）的对比试验，探究其受输电线与灌丛的影响方式及影响幅度。研究观察到，输电线通过电磁场（EMF）间接作用于植物，因此对应样地内的一枝黄花株高更高；而灌丛则通过各类途径与一枝黄花产生竞争。本研究仅采用样方框（quadrat）、温度计与米尺开展重复测量，为实现完全随机化设计，本研究于每个工作日选取仅受目标干扰因素影响、排除其他无关影响因子的随机样点开展实验。本研究所得结果具有统计学显著性，且与预设预测相符。
