Shuitu Baochi Xuebao, 2018 以吉林省农业科学院黑土有机培肥定位试验基地为平台，研究了不同种类有机肥（堆腐肥、鸡粪、牛粪和猪粪）施用对土壤及不同粒级团聚体中有机碳和腐殖质组成的影响。结果表明：与不施肥（CK）和单施化肥（NPK）相比，有机肥配施化肥显著（P0.25 mm粒级团聚体有机碳含量高于其他有机肥处理，且2~0.25 mm粒级团聚体有机碳含量显著高于鸡粪处理；从不同粒级团聚体中腐殖质组分的分布来看，施用堆腐肥后，2~0.25 mm粒级团聚体中HAC和HUC含量显著高于猪粪处理，而0.25~0.053，

Shuitu Baochi Xuebao, 2018 为揭示不同培肥措施对采煤塌陷区复垦土壤氮素矿化特征，采用间歇淋洗好气培养法，研究了不施肥（CK）、单施化肥（CF）、单施有机肥（M）、化肥配施有机肥（MCF）和化肥配施生物有机肥（MCFB）5种培肥措施对复垦4年和8年土壤矿质态氮和可溶性有机氮变化及氮素矿化特征的影响。结果表明：间歇淋洗好气培养过程中，复垦8年土壤累积NO3-—N产生量较4年增加2.63%~26.83%，NH4+—N累积产生量增加12.50%~32.14%，可溶性有机氮（SON）累积产生量在CF和M处理下减少31.59%~62.50 ...

Shuitu Baochi Xuebao, 2008 采用田间试验研究了不同施肥处理对莴笋产量、品质和经济效益的影响。结果表明,在CK(N15P5K10)基础上分别增施氮肥、磷肥、钾肥、硼肥或有机肥可使莴笋增产19.4%~66.4%,以施用有机肥菜籽粕增产作用最大。有机肥泥炭和菜籽粕处理使莴笋茎硝酸盐含量分别降低9.3%和18.0%。不同施肥处理均提高了莴笋叶和茎维生素C含量,菜籽粕处理莴笋叶维生素C含量增幅最大(为16.5%),泥炭和菜籽粕处理莴笋茎维生素C含量均显著高于其他处理。增施钾肥处理对提高莴笋叶还原糖含量作用最大(达10.0 ...
