肥料混施对赤红壤氮磷淋失特征的影响

Shuitu Baochi Xuebao, 2008
采用室内模拟土柱淋洗方法研究了无机复合肥、有机复合肥、猪粪堆肥和花生麸4种肥料单施和两两混施条件下氮磷在赤红壤中的淋失特征。结果表明,各处理总氮淋失率在43.2%～74.8%之间,总磷淋失率在0.01%～0.08%之间,赤红壤中肥料氮淋失严重,肥料磷淋失有限。肥料单施处理的无机氮淋失量和有机氮基本相近,肥料混施处理的无机氮淋失量远高于有机氮;各施肥处理磷的淋失均以颗粒磷为主。肥料混施显著增加铵态氮和无机氮淋失,减少有机氮和总氮淋失。猪粪与复合肥混施减少颗粒磷和总磷淋失 ...

不同施肥处理对稻田氮素径流和渗漏损失的影响

Shuitu Baochi Xuebao, 2016
采用田间试验，研究了不施肥（CK）、常规施肥（CF）、90%常规施肥（90%CF）、80%常规施肥（80%CF）、控释复合肥（CRF）和有机—无机肥配施（MF）6种施肥处理对稻田径流和渗漏损失的影响。结果表明：水稻田面水总氮（TN）和铵态氮（NH4+—N）浓度在施肥后第2 d达到峰值，之后快速下降，第7 d后降至峰值的15%以下并趋于稳定，控制稻田氮素流失最关键的时间为施肥后1周。减量施肥可以有效降低田面水和渗漏水的氮素浓度。不同施肥处理（CK除外）TN径流损失量和氮素流失率分别为8.81～15.78 ...
