- 摘要:
- 为全面了解不同土壤改良模式对铁尾矿复垦效果的影响,在邢台市南沟地区选取具有代表性的2种土壤改良模式(客土改良模式、半客土改良模式),研究不同土壤改良模式下铁尾矿复垦土壤的改良效果,并与对照铁尾矿进行对比分析。结果表明:半客土改良模式物种多样性指数和均匀度指数均较高,客土改良模式物种丰富度明显高于尾矿和半客土改良模式;2种土壤改良模式下的土壤容重、毛管孔隙度明显增加,土壤总孔隙度和土壤毛管持水量减少,2种模式的改良效果相似;有机质含量和全氮、全钾、全镁含量均呈现增加趋势,全磷、全钙含量减少;各种速效养分含量明显提高,其趋势基本一致,且均有一定的表聚性。
- Abstract:
- In order to understand the effect of different improvement measures on the soil properties of iron tailings,in the south ditch area selected sample of two soil improvement mode (foreign soil improvement measure,semi-foreign soil improvement measure),different improment measures on the reclamation effect of iron tailings was investigated and compared with control bare tailings.The results showed that the diversity index and evenness index of semi-foreign soil improvement measure were high,compared with control bare tailings and semi-foreign soil improvement measure,the richness of foreign soil improvement measure was significantly high;soil bulk density and capillary porosity showed an increasing trend,total porosity and soil capillary hold water were decreased,the effect of the two improvement measures were similar;the content of soil organic matter,total nitrogen,total potassium and full magnesium showed an increasing trend,the content of total phosphorus and total Ca were decreased;the content of variety of available nutrients significantly increased,the trend was consistent and there was a certain cohesion of the table.
