Abstract: The effects of short-term different fertilizing treatments on repairing fertility of soil degraded by highway construction and growth of Neyraudia reynaudiana were studied by greenhouse pot experiment with Neyraudia reynaudiana.The results showed:vermicompost and cattle manure treatment,compared with chemical fertilizer and contrast treatment,significantly decreased the soil bulk density and increased soil pH value and soil porosity,field moisture capacity,organic matter and total nitrogen (P <0.001); under the vermicompost and cattle manure treatment,the Neyraudia reynaudiana plant dry weight,height,tiller number,root total length,root surface area,root volume,root average diameter and N,P,K nutrient accumulation were obviously higher than that under chemical fertilizer and contrast treatment (P <0.05).Chemical fertilizer only inhibited the growth of Neyraudia reynaudiana,plant growth characteristics were worse than contrast.Cattle manure treatment and vermicompost produced by treating cattle manure with earthworm treatment were almost the same in the effect of soil physical and chemical comprehensive quality,but vermicompost treatment was more effective in promoting the Neyraudia reynaudiana plant tiller and root development than cattle manure treatment.In short-term,vermicompost and cattle manure treatment are better for improvement of soil physical properties,enhancing soil physical and chemical comprehensive quality and promoting corp growth of land degraded by highway construction compared with chemical fertilizer treatment.Organic fertilizer,especially vermicompost is an effective treatment for rapidly repairing land degraded by construction.
