英文摘要	Background: Inappropriate disposal of the plastic mulching debris could create macroplastics (MaPs) and microplastics (MiPs) pollution in agricultural soil. Methods: To study the effects of farming systems on accumulation and distribution of agricultural plastic debris, research was carried out on two farming systems in Northwest China. Farming in Wutong Village (S1) is characterized by small plots and low-intensity machine tillage while farming in Shihezi (S2) is characterized by large plots and high-intensity machine tillage. In September 2017, we selected six fields in Si, three fields with 6-8 years of continuous plastic mulching (CM) as well as three fields with over 30 years of intermittent mulching (IM). In S2, we selected five cotton fields with 6, 7, 8, 15 and 18 years of continuous mulching. In both regions, MaPs and MiPs from soil surface to 30 cm depth (0-30 cm) were sampled. Results: The results showed that in Si, MaPs mass in fields with 6-8 years CM (i.e., 97.4kg.ha(-1)) were significantly higher than in fields with 30 years IM (i.e., 53.7 kg.ha(-1)). MaPs in size category of 10-50 cm(2) accounted for 46.9% in fields of CM and 44.5% in fields of IM of total collected MaPs number. In S2, MaPs mass ranged from 43.5 kg.ha(-1) to 148 kg.ha(-1). MaPs in size category of 2-10 cm(2) account for 41.1% of total collected MaPs number while 0.25-2 cm(2) accounted for 40.6%. MiPs in S1 were mainly detected in fields with over 30 years of intermittent mulching (up to 2,200 particles.kg(-1) soil), whereas in S2 were detected in all fields (up to 900 particles.kg(-1) soil). The results indicated farming systems could substantially affect the accumulation and distribution of agricultural plastic debris. Continuous plastic mulching could accumulate higher amount of MaPs than intermittent plastic mulching. High-intensity machine tillage could lead to higher fragmentation of MaPs and more severe MiPs pollution. These results suggest that agricultural plastic regulations are needed.
