Abstract

The invention discloses an application of a folium isatidis decoction in neutralizing acidity of an acid rain as well as improving and treating an acidified soil. According to the invention, an obvious neutralizing effect of the folium isatidis decoction on the acidity of artificial imitated rainwater is found for the first time; and the folium isatidis decoction can be also used for degrading pollutants such as nitrate ions and sulfate ions. At present, as folium isatidis is cultivated and planted in various domestic places, the folium isatidis is very convenient to get; the folium isatidis can be used for experimental research and on-site research on treatment according to local conditions; however, further deep researches on the function mechanism and an on-site treatment effect of the folium isatidis are also needed. As the use of the folium isatidis decoction in neutralizing the acidity of the artificial imitated rainwater and degrading the pollutants such as nitrate ions and sulfate ions is first developed in the research and an obvious effect is obtained, the folium isatidis decoction can be used for neutralizing the acidity of the rainwater, degrading the pollutants such as nitrate ions and sulfate ions and improving and treating the acidified soil, so that a novel way and a novel idea in comprehensive treating the acidified soil are started.

Description

Technical field: [0001] The invention belongs to the field of soil and acid rain pollution control, and in particular relates to the application of Folium folium Folium decoction in neutralizing the acidity of acid rain, improving and treating acidified soil. Background technique: [0002] Acid rain refers to rain and snow or other forms of atmospheric precipitation with a pH value less than 5.6 (Qi Feng et al., 2011). Acid rain is known as "the god of death in the air" because of its harm to the ecological environment, forests, crops and human health. It is one of the global regional disasters encountered by human beings. According to reports, due to the reduction of lake acidity, fish died in lakes in Canada and other countries (Hessen, 1998); due to the harm of acid deposition in Southwest my country, there have been reports of large coniferous forests dying (Yang Benhong, 2000) It is estimated that in Jiangsu, Zhejiang and other provinces, about 10 million hectares of fa...
