Abstract

Abstract: In this study, arbuscular mycorrhizal fungi （AMF） were inoculated in the loess land of Zhangjiamao mining area in north Shaanxi province, and the common local legume plant pea （Pisum sativum L.） was planted to monitor its growth and quality and yield, and soil physical and chemical properties. The results showed that the root colonization rate of pea increased by 16.11 percentage points, and a good symbiotic relationship between mycorrhizal and pea could be formed. Compared with the control treatment, the plant height and SPAD of pea increased by 52.34% and 29.35% （P<0.05）, the biomass and yield of straw increased by 22.69% and 20.61%, the total nitrogen and potassium content of mycorrhizal plant increased by 12.72% and 22.19% （P<0.05）, and the total nitrogen and potassium absorption of pea plant per hectare increased by 38.74% and 51.89%, respectively. The soluble protein and sugar of pea per hectare increased by 20.09% and 47.99%, respectively. Mycorrhizal inoculation increased soil conductivity, available phosphorus, available potassium, organic matter, total potassium, total phosphorus and total nitrogen, and decreased pH, but the difference was not significant. Inoculated mycorrhiza can promote the productivity of plants in the Loess Plateau, and microbial reclamation can provide a good potential for the improvement of productivity in the Loess Plateau.
