Description

technical field [0001] The invention relates to the field of agriculture and forestry, mainly soil restoration technology. Background technique [0002] The rapid development of my country's industry has led to the emergence of acid deposition problems. Studies have shown that southern my country has become the third largest acid deposition area after Europe and the United States. The emergence of acid deposition problems has led to the occurrence of soil acidification. Field and indoor experiments have shown that , In the past few decades, acid deposition has led to the acidification of large areas of soil in China. The traditional method of remediation of acidified soil is to apply lime, but it is very expensive and labor-intensive. Foreign methods of improving acidified soil mainly include the application of lime, manure, Plant ash, green manure and waste pulp from paper mills, etc. The traditional domestic method of acidifying soil remediation is to apply lime, and there a...
