摘要:
为明确酸性植烟土壤施用石灰、绿肥和生物有机肥等改土物料组合的效果,研究了酸性土壤单施石灰、石灰+绿肥、石灰+绿肥+生物有机肥等改土物料后土壤 pH 和土壤理化性状动态变化。结果表明:(1)施用改土物料之后,植烟土壤 pH 表现为先升后降的阶段性变化,至烤烟移栽 60d 后逐渐趋于稳定;单施石灰的植烟土壤容重呈升高趋势,石灰+绿肥、石灰+绿肥+生物有机肥处理的土壤容重呈下降趋势;植烟土壤孔隙度、水分和有机质含量呈“高低高”的阶段性变化;植烟土壤碱解氮含量呈“低高低高的阶段性变化;土壤有效磷和速效钾含量呈递增趋势。(2)至烤烟移栽后 120d,施用改土物料较对照能提高土壤 pH 0.32~1.07 个...
摘要(英文):
In order to clarify the effect of lime, green manure and bio-organic fertilizer used in acid tobacco- planting soil, the dynamic changes of soil pH and physical and chemical properties were studied by applying lime, lime + green manure and lime + green manure +bio-organic fertilizer. Results showed that: (1) After application of soil amelioration materials, pH value of tobacco-planting soil showed a trend of first increasing and then decreasing fall, and gradually tended to be stable 60 days after transplant. The bulk density of tobacco-plantin...
