不同复垦方式对煤矿复垦区土壤养分状况的影响
The Influence of Different Reclamation Modes on Soil Nutrient in Coal Mine Plots
摘要
Abstract
This paper took the reclamation plots filled with fly ash,coal gangue,Yellow River sediment,lake sediments and the plots prepared for reclamation as the research object in Jining to explore the influences of different reclamation modes on soil nutrients and the total level of soil fertility.The results showed that the available nitrogen,available phosphorus and organic matter increased significantly 28.07 mg/kg,45.15 mg/kg and 1.14％ respectively at 0-30 cm depth of the plot filled with coal gangue.The content of available potassium for the plot filled with Yellow River sediment was highest.Fly ash filling had the worst effect on the content of the available nitrogen.Pre-reclamation had the least influence on the available phosphorus,available potassium and organic matter.At the 30-50 cm depth,fly ash filling had the biggest influence on the soil fertility.The available nitrogen,available phosphorus,available potassium and organic matter were 68.5％、89.0％、71.4％、177.3％ higher than the Control plot.The influence on the total level of soil fertility of five reclamation modes was in sequence of the plot filled with fly ash ＞ the plot filled with coal gangue ＞ the plot filled with Yellow River sediment ＞ the plot filled with lake sediments ＞ the plot prepared for reclamation,at the 30-50 cm depth,the sequence was the plot filled with lake sediments ＞ the plot filled with fly ash ＞ the plot prepared for reclamation ＞ the plot filled with Yellow River sediment ＞ the plot filled with coal gangue.Comprehensive consideration about soil nutrient and the total level of soil fertility,fly ash filling and lake sediments filling had the best effect on the recovery of soil fertility in Jining,and should get further popularization.关键词
