Soil Quality And Density Effects On The Number Of Stems In Goldenrods

The location in which the study was conducted was the grasslands in Stong Pond at York University. The data was collected over a span of two days, a week apart each collection. The first 25 replicates were obtained on October 19, 2015. The temperature was around 16 degrees Celsius, with dark skies full of grey rain clouds. The second day the second set of replicates were collected October 26, 2015. Where the temperature was around 11 degrees Celsius with a partially cloudy sky. The data was collected by placing quadrants 3 steps apart one another starting from the waters edge of Stong pond all the way to the roadside of the grassland. Within the quadrant, the number of goldenrods will be noted as well as the total number of branches, collectively. Soil quality is going to be determined through soil temperature as goldenrods have an ideal soil temperature of 10 degrees Celsius. This will be sampled using a thermometer and categorized as, low (7-9 degrees Celsius), ideal (10 degrees Celsius) and high (11-13 degrees Celsius).

本研究的开展地点为约克大学（York University）斯通池塘（Stong Pond）周边的草原生境。数据采集分两日完成，两次采集间隔一周。第一批次25组重复采样单元于2015年10月19日采集完成，当日气温约16摄氏度，天空阴沉且布满灰色雨云。第二批次重复采样单元于2015年10月26日采集完成，当日气温约11摄氏度，天空局部多云。采样时以斯通池塘水岸为起点，向草原公路方向布设样方（quadrant），样方间距为3步，全程依次布设。在每个样方内，将同步记录一枝黄花（goldenrods）的种群数量与总分枝数。本研究通过土壤温度表征土壤质量，因一枝黄花的适宜生长土壤温度为10摄氏度。土壤温度采样将使用温度计完成，并按如下标准分类：低温组（7-9摄氏度）、适宜组（10摄氏度）及高温组（11-13摄氏度）。
