不同处理方式的废弃宅基地整治土壤改良研究

Study on Soil Improvement of Different Treatment Methods in the Treatment of Abandoned Homestead

摘要: 通过小区试验，研究了不同处理方式的废弃宅基地整治后对土壤容重、土壤团聚体、有机质等土壤理化性质的不同影响。得出在废弃宅基地整治项目土壤改良时，土壤改良时加施有机肥更易使耕作层表层土壤容重显著减小，土壤有机质含量显著增加，更有利于增加表层1~2 mm、0.25~1 mm粒径土壤团聚体含量，有利于作物生长，提升土壤肥力，改善土壤生物环境，综合提高耕地质量及产出。其次是加施粉煤灰、熟化剂。

Abstract: Through plot experiment, the different effects of different treatment methods on soil bulk density, soil aggregate, organic matter and other soil physical and chemical properties were studied. It is concluded that during the soil improvement of the abandoned homestead remediation project, the application of organic fertilizer during soil improvement is easier to significantly reduce the surface soil bulk density of the cultivated layer and significantly increase the content of soil organic matter, which is more conducive to increase the content of soil aggregates with particle sizes of 1~2 mm and 0.25~1 mm, which is conducive to crop growth, improve soil fertility and improve the soil biological environment, Comprehensively improve the quality and output of cultivated land. The second is to add fly ash and curing agent.
