AB  - A total of six treatments, including continuous conventional tillage (CT), rotary 
      tillage (RT), subsoiling (ST), no-tillage (NT), conventional-no tillage (CT-NT) 
      and subsoiling-no tillage (ST-NT), were conducted to examine the effects of 
      different tillage types on soil aggregates distribution and stability of 
      irrigated sierozem on continuous 8-year-tillage maize fields in the Gansu Yellow 
      River irrigated area in 2014-2017. The results showed that the aggregation and 
      stability of large aggregates in 0-40 cm soil layer were increased by NT and 
      ST-NT treatments, while the size distribution and stability in plough layer were 
      significantly decreased by CT and RT treatments due to strong soil disturbance. 
      Compared with RT, the mechanical stability of aggregates under dry sieving NT was 
      the best. The contents of >0.25 mm aggregate (R(0.25)), mean weight diameter 
      (MWD) and geometric mean diameter (GMD) increased by 5.8%, 8.0%, and 13.0%, 
      respectively, and fractal dimension (D) decreased by 3.6%. The water-stable 
      aggregates in ST-NT was the best, with R(0.25), MWD and GMD increased by 55.3%, 
      15.1% and 8.7%, respectively, and D value decreased by 0.8%. The percentage of 
      aggregate destruction (PAD) and unstable aggregate index (E(LT)) of NT and ST-NT 
      treatments were the lowest. PAD was reduced by 5.9% and 7.7% compared with RT, 
      E(LT) was reduced by 5.8% and 7.2%, respectively. All the results indicated that 
      the subsoiling-notillage (ST-NT) rotation mode was more conducive to the 
      enhancement of soil aggregate content and stability and consistent with the local 
      farmers operating habits, which would be an ideal tillage method and had certain 
      application value for the sustainable agricultural development in this area.
