摘要
对4种施肥(条施生物有机菌肥、条施复混肥、撒施生物有机菌肥和撒施复混肥)处理后的梁山慈竹林土壤有机碳和微生物量碳进行了研究。结果表明:4种施肥处理的土壤剖面有机碳和微生物量碳含量均高于对照,分别比对照增加了17.4%～39.1%和67.9%～137.1%。施肥种类对土壤有机碳含量影响差异显著(p<0.05),F=6.15>F0.05(1.6),施肥方式对土壤有机碳含量影响差异不显著,F=5.72<F0.05(1.6),二者的交互作用影响差异显著(p<0.05),且F交互作用>F施肥种类。施肥种类对土壤微生物量碳含量影响差异极显著(p<0.01),施肥方式对土壤生物量碳含量影响差异显著(p<0.05),F=23.62>F0.01(1.6),F=10.51>F0.05(1.6),二者的交互作用差异极显著(p<0.01),F=38.91>F0.01(1.6),且F交互作用>F施肥种类。研究结果说明,适当的施肥种类配合合理的施肥方式有利于土壤有机碳和微生物量碳的提高。
Four fertilization treatments（row replacement biological organic bacterial manure,row replacement compound fertilizer,broadcasting biological organic bacterial manure and broadcasting compound fertilizer） were conducted to study the effect fertilization on soil organic carbon（SOC） and soil microbial biomass carbon（S-MBC） in D.farinosus forest.The results showed that the contents of SOC and S-MBC under four fertilization treatments were higher than that of the control,which were increased by 17.4%～39.1% and 67.9%～137.1%,respectively.Fertilization types had a significant differences with SOC（p0.05）,F=6.15F0.05（1.6）.There was no significant difference between fertilization modes and SOC,F=5.72F0.05（1.6）.The interaction of fertilization types and modes had a significant difference with SOC（p0.05）,Finteraction Ffertilization types.Fertilization types had an extremely significant difference with S-MBC（p0.01）,fertilization modes had a significant difference with SOC（p0.05）,F=23.62F0.01（1.6）,F=10.51F0.05（1.6）.The interaction of fertilization types and modes had an extremely significant difference with S-MBC（p0.01）,F=38.91F0.01（1.6）,Finteraction Ffertilization types.Results indicated that the appropriate fertilization types and the reasonable fertilization modes could significantly improve the contents of SOC and S-MBC of D.farinosus forest.
