Effects of returning materials on the electrical conductivity of reclaimed soil and crop yield

In order to explore the maturation effects of different returning materials in the soil reclamation of abandoned homesteads, this paper studied the characteristics of the soil conductivity profile distribution after adding fly ash, organic fertilizer and curing agent three kinds of returning materials, and the three consecutive years of crops yield. The results showed after three consecutive seasons, the soil conductivity of the cultivated layer decreased by applying organic fertilizer treatment, and the deep soil conductivity increased, which can reduce the possibility of secondary salinization. Crop yields of different returning materials are different. Compared with the other two returning materials, the application of organic fertilizer can better mature the abandoned homesteads and reclaim the soil, and promote the growth of winter wheat and summer corn.
