为了解早产高效雷竹林施肥与土壤重金属有效态含量关系,在浙江省雷竹主产区布置了肥料试验,动态采集了各处理土壤样品,用ICP法分析了土壤重金属有效态含量。结果表明:Pb、Cd、Zn、Cr和Cu5种重金属有效态含量,无论是在有机肥化肥混合处理区还是纯化肥处理区随时间变化均有较大波动,5种重金属有效态含量均表现为8月份含量较高,以后则明显下降,到次年4月份又明显升高。比较不同施肥处理土壤重金属有效态含量发现,有效Zn和有效Cr含量在3个不同用量的纯化肥间有显著差异 ...

生物有机肥部分替代化肥对莴笋及土壤理化性质和微生物的影响

Shuitu Baochi Xuebao, 2019
以莴笋为试材，通过田间试验，以不施肥（CK）和常规施肥（CF）为对照，研究常规施肥总施肥量减量20%（F1）和30%（F2），配施3 000 kg/hm2（B1），6 000 kg/hm2（B2）生物有机肥对莴笋干物质积累、养分吸收、肥料利用率及土壤理化性质和土壤微生物数量的影响，为莴笋合理施肥提供科学依据。结果表明，与CF相比，F1B2处理莴笋根、茎、叶干物质积累量分别增加5.74%，22.19%和17.82%，氮、磷、钾养分积累量分别提高128.81%，113.19%和23.15 ...

氮肥优化减施对土壤氮磷累积及蔬菜产量品质的影响

Shuitu Baochi Xuebao, 2011
针对长期不合理高化肥投入量导致城郊区菜地土壤环境恶化的现状,为探讨氮肥减施对城郊区菜地土壤氮磷累积及蔬菜产量品质的影响,应用田间小区试验,研究了长沙市郊2种不同菜地土壤中,氮肥减施20%与缓释尿素,脲酶抑制剂/硝化抑制剂,土壤调理剂配合施用的环境和农学效应。结果表明:与常规施肥处理相比,采用缓释尿素减施20%化学氮肥(80%N(CRU))有效降低了菜地土壤Olsen-P和NO3--N的含量,减少了其面源污染风险,但该处理蔬菜可食部分容易累积硝酸盐,也增加了食用风险;通过添加脲酶抑制剂/硝化抑制剂减施20%
