Study on the Improvement Effect of Biomass Amendment on Soil in Open-pit Coal Mines
摘要
Abstract
In order to effectively improve the problem of soil salinization and impoverishment around open-pit coal mines,biomass composite materials were subjected to pyrolysis and modification treatment to prepare a new type of biomass amendment CK-1.The effect of the dosage of biomass amendment CK-1 on the pH value,conductivity,salt content,and effective nutrient content of the soil in the target open-pit coal mining area was investigated through leaching experiments.The results showed that the addition of biomass amendment CK-1 can effectively reduce the pH value and salt content of soil samples in the target open-pit coal mining area,slightly decrease the soil conductivity,and effectively increase the content of effective nutrients in the soil.When the dosage of biomass amendment CK-1 was 2%,the pH value of the soil in the 0~10 cm soil layer after leaching treatment decreased to 8.11,the salt content decreased to 0.11 g/kg,the conductivity was 301.3 μS/cm,and the contents of liquid ammonia,available phosphorus,and available potassium increased to 48.54 mg/kg,7.84 mg/kg,and 128.35 mg/kg,respectively.The degree of soil salinization and impoverishment were significantly improved.The research results suggest that biomass amendment CK-1 can have a good improvement effect on the soil around the target open-pit coal mine.关键词
