长期不同施肥管理对稻田土壤有机碳库特征的影响

Shuitu Baochi Xuebao, 2011
以19年的长期定位施肥土壤为材料,研究不同施肥管理:不施肥(CK),施无机肥(N、NP、NK、NPK),施有机肥(OM),有机-无机配施(F、F’)下稻田耕层土壤有机碳库组分及含量变化。结果表明:不同施肥方式对土壤有机碳及其组分有显著影响,土壤总有机碳(TOC)变化趋势为有机无机配施(平均12.34g/kg)>单施有机肥(平均12.15g/kg)>无肥(平均10.56g/kg)>化肥(平均9.78g/kg);有机肥和化肥配施土壤微生物量碳(SMBC)、水溶性有机碳(WSOC)、轻组有机碳(LFOC ...

不同林下植被兴安落叶松林土壤活性有机碳组分特征

Shuitu Baochi Xuebao
目的研究大兴安岭不同林下植被兴安落叶松林土壤活性有机碳组分特征，为大兴安岭地区森林土壤活性有机碳及其稳定性研究提供科学依据。方法以4种林下植被兴安落叶松林（兴安杜鹃-兴安落叶松林（Rhododendron dauricum-Larix gmelinii forest，简称DJL）、杜香-兴安落叶松林（Ledum palustre-Larix. gmelinii forest，简称DXL）、苔草-兴安落叶松林（Carex tristachya-Larix gmelinii forest，简称TCL）和苔藓-

菇渣有机肥配施脱硫石膏对黄河三角洲盐碱土

Shuitu Baochi Xuebao
[目的] 为探讨菇渣有机肥与脱硫石膏对盐碱土有机碳组分及碳库管理指数的影响。[方法] 以黄河三角洲新垦殖小麦—玉米轮作地为研究对象,采用随机区组试验方法,设置不施肥(CK)、农民常用施肥(CN)、菇渣有机肥(MCOF)、菇渣有机肥+脱硫石膏(MCOG)4个处理,通过3年田间施肥处理。[结果] 菇渣有机肥与脱硫石膏配施显著降低0—20 cm土壤盐碱度,提高土壤氮磷钾养分含量和阳离子交换量(p＜0.05);各处理0—20 cm土层总有机碳(TOC)、易氧化有机碳(EOC)、微生物量碳(MBC)含量高于20 ...
