Abstract:

The aim is to explore the effects of tillage methods on soil physical properties and wheat growth in arid farmland of Xinjiang. The soil bulk density, porosity, soil water content, soil three-phase ratio and wheat yield were measured by field sampling and laboratory drying weighing under three tillage modes of no-tillage, traditional tillage and subsoiling. The results showed that soil bulk density, porosity, water content, three-phase ratio R and yield showed some differences under different tillage methods. Compared with no-tillage, traditional tillage and subsoiling reduced soil bulk density, increased soil porosity and soil water content, and improved the three-phase ratio of soil. In particular, the subsoiling treatment significantly improved soil bulk density and porosity, and obtained the highest yield of wheat, which increased by 20.71% and 24.28% respectively compared with that of traditional tillage and no-tillage. Therefore, subsoiling is conducive to improving soil structure, soil physical properties and wheat yield.

Key words: tillage, subsoiling, soil physical properties, arid land, yield
