作者选择日本夏橙实生苗研究了酸雨对其生长的影响,并测定了酸雨对柿和梨等果实的污损。在预加试验中,配置了各种盐类组成的模拟酸雨和单一的硫酸性水作对比,结果二种酸性水在夏橙和黄瓜、柿子椒、四季萝卜等各种蔬菜上所出现的伤害无差别。因此试验全部采用硫酸酸性水作酸雨进行实验。
The author chose the Japanese summer orange seedlings to study the impact of acid rain on its growth, and determination of acid rain on persimmon and pear and other fruit defaced. In the pre-test, the simulated acid rain with various salt compositions was compared with the single sulfated water. As a result, the damage of the two kinds of acidic water on various vegetables such as summer orange and cucumber, bell pepper, seasons radish and the like difference. Therefore, all experiments using acidic sulfuric acid for acid rain experiment.
