Effect of Earthworm Inoculation on Repairing Fertility of Lateritic Red Soil Degraded by Highway Construction and Plant Growth of Amaranthus hypochondriacus L.

摘要: 采用盆栽籽粒苋实验法,研究接种赤子爱胜蚓和壮伟环毛蚓对公路工程损毁赤红壤肥力修复和植物生长的影响。试验设计4个处理,分别为对照(CK)、接种20条赤子爱胜蚓(20Ef)、接种20条壮伟环毛蚓(20Ar)以及分别接种10条赤子爱胜蚓和壮伟环毛蚓(10Ef+10Ar)。结果表明:接种蚯蚓处理后,籽粒苋株高、茎粗、生物量和植株氮磷钾养分累积量显著高于CK处理(P<0.05)。接种表栖型赤子爱胜蚓较接种内栖型壮伟环毛蚓更能促进籽粒苋植株生长和养分累积,但组合接种效果低于单独接种,呈现出20Ef>20Ar>10Ef+10Ar>CK的趋势。蚯蚓活动有助于土壤有机质的分解和土壤养分的活化,能快速提高土壤供肥能力,利于作物吸收,促进作物生长。蚯蚓对土壤肥力的影响与蚯蚓生态类型、接种地土壤性状关系密切。在土壤修复中,根据不同土壤特征接种不同生态类型蚯蚓和添加适宜有机物非常有必要。Abstract: Two earthworm species,Eisenia foetida and Amynthas robustus,were grown in a pot experiment with Amaranthus hypochondriacus L.to study the effects of the different ecological types of earthworms on the fertility recovery and ecological restoration of the degraded lateritic red soil due to highway construction.Three treatments,i.e.,20 E.foetida,20 A.robustus,and 10 E.foetida plus 10 A.robustus,along with control(CK without earthworm inoculated)were applied.The results showed that the plant height,stem diameter,biomass and NPK accumulation of the A.hypochondriacus L.plants in the treatment groups were significantly higher than those in CK(P<0.05).E.foetida(i.e.,an epigeic earthworm species)enhanced the plant growth and nutrient accumulation more significantly than A.robustus(i.e.,an endogeic species).By using both earthworm species simultaneously in the soil,no synergistic effect was observed.Nonetheless,the presence of either of the earthworms enhanced the organic decomposition and nutrient activation in the soil significantly improving the plant growth.However,since soil improvement depends on the properties and conditions of the soil as well as the species of the inoculated earthworms,it would be necessary to firstly obtain the relevant information prior to the implementation.
