不同用量猪粪对红壤花生坡地水土流失和磷素流失的影响

Shuitu Baochi Xuebao, 2017
通过田间径流微区定位试验，以中亚热带3种典型母质（花岗岩、红砂岩、红黏土）发育红壤花生坡地为研究对象，以当地常规化肥用量处理为对照，连续3年研究了在常规化肥用量减半条件下配施6个不同用量腐熟猪粪（猪粪含有0，0.5，1，2，4，8倍的对照处理磷用量）对红壤花生坡地水土流失和磷素流失的影响，以期为典型红壤旱地区合理施用猪粪提供科学依据。结果表明：化肥减半配施猪粪处理能有效降低红壤坡地的产流产沙，但随着猪粪用量的增加，径流水和泥沙磷含量均呈线性增加，环境风险增大。径流量和泥沙量均为花岗岩红壤>红砂岩红壤 ...

采煤塌陷区复垦土壤团聚体碳氮分布对施肥的响应

Shuitu Baochi Xuebao, 2018
为了揭示长期不同培肥措施下采煤塌陷区复垦土壤团聚体有机碳氮含量的变化规律，通过干筛法研究了不施肥（CK）、单施有机肥（M）、单施化肥（CF）、有机肥与化肥配施（MCF）、生物有机肥与化肥配施（MCFB）5种培肥措施下复垦4年和8年土壤各粒级团聚体分布组成特征以及各团聚体有机碳氮含量的变化规律。结果表明，复垦土壤团聚体含量随粒级减小呈先减小后增大的变化趋势，其中以3~2 mm粒级团聚体含量最低，占团聚体总量2%~3%，以2~1 mm粒级团聚体含量最高，占团聚体总量25%~31 ...

化肥减量配施秸秆和有机肥对酸化土壤改良及侵蚀阻控的影响

Shuitu Baochi Xuebao
[目的] 合理施用秸秆和有机肥能有效改良土壤,对土壤酸度和抗侵蚀能力产生积极作用。[方法] 以酸化红壤为研究对象,对比常规施肥(CK),化肥减量(30%)和秸秆还田(6 000 kg/hm2,FSM0),及化肥减量(30%)加上秸秆还田(6 000 kg/hm2)和配施不同梯度有机肥(1 500,3 000,4 500,6 000 kg/hm2)(FSM1、FSM2、FSM3、FSM4)对油菜生长各阶段土壤性质和产量的影响。[结果] 化肥减量配施秸秆和有机肥显著改善土壤酸度和养分状况(p＜0.05 ...
