为了根治水土流失,充分发挥植物根系含水固沙的作用,我们环保小组为此进行了实验研究。 首先,我们将3棵柳树分别栽种在不同的土壤中,在相同的水分、温度、湿度和光照下进行对比实验研究,得到在不同的土质中柳树根系生长状况,见表1。
In order to eradicate soil erosion and give full play to the role of water and sediment fixation in the roots of plants, our environmental protection team conducted an experimental study for this purpose.
