Abstract

Abstract:

In this study，we set up 3 different fertilization treatments（T1，applying 1 t of pig manure bacteria mattress fertilizer per 667 m²；T2，applying 2 t of pig manure bacteria mattress fertilizer per 667 m²；T3，applying 1 t of commercial organic fertilizer per 667 m²），and studied the effects of pig stocking and bacteria mattress fertilizer technology on soil fertility and environmental quality of newly reclaimed farmland. The results showed that pig manure bacteria mattress fertilizer can significantly increase the pH value of the soil， thereby facilitating the improvement of the soil's acidity and alkalinity. All three treatments can increase the content of organic matter，nitrogen，phosphorus，and potassium in the soil，especially T2 showed the best improvement effect on increasing the content of organic matter，nitrogen，phosphorus，potassium. And the content of four heavy metals including arsenic，cadmium，mercury，and copper in the soil of T2 increased obviously，while the content of heavy metals in the soil treated by T1 and T3 fluctuated relatively little，indicating that the application of pig manure bacteria materess fertilizer or organic fertilizer had the risk of accumulating some heavy metals in the soil，which was related to the amount of fertilizer applied. Among them，the accumulation of arsenic in the soil was more obvious and the pollution risk was greater. It was recommended to apply in moderation，strengthen the management of use，and carry out regular and continuous monitoring of the soil to avoid the risk of heavy metal pollution in soil and crops. Furthermore，the pig stocking and bacteria mattress fertilizer technology had a relatively significant effect on improving the fertility of newly reclaimed farmland and increasing the economic income of farmers，demonstrating good application value and potential. The research results have certain reference and guiding value for the study of techniques to enhance the fertility of newly cultivated farmland.

Key words: newly reclaimed farmland, soil fertility enhancement, soil environmental quality, pig manure bacteria mattress fertilizer
