丹江口库区石渣土土壤水分有效性研究

Shuitu Baochi Xuebao, 2002
土壤水分有效性的高低是制约石渣土生产能力的关键因素之一。对丹江口库区郧县石渣土 3种不同土石比土壤水分有效性的研究表明 :土壤水分有效性与土壤中的土 (<2 mm)石 (>2 mm)比关系密切。土壤蒸发、持水、导水和供水能力均与土壤中的土石比的大小有关。 3种土壤的持水能力 ,以石砾含量较少、质地较粘的土壤最强 ,以石砾含量较多、质地为壤质的土壤最低。而土壤水分蒸发能力与砾石含量呈负相关 ,土壤水分扩散率则与砾石含量呈正相关。适中土石比的土壤可提高入渗性能 ,减少蒸发量 ,提高供水性能。

长期不同施肥制度对农田黑土有机质和氮素的影响

Shuitu Baochi Xuebao, 2005
以黑龙江省海伦黑土地区的农田长期（1985～2003年）定位试验土样为材料，对不同施肥处理土壤有机质含量、土壤全氮进行了系统研究。结果表明，长期无肥处理土壤有机质含量、全氮含量最低；长期施用氮肥、氮磷肥、有机肥处理土壤有机质含量、全氮含量居中；有机肥与化肥配合施用比无肥处理可显著提高有机质水平，增加土壤全氮含量。各处理C／N比值在9．91～13．10之间变动。
