Abstract: To effectively improve the perennial artificial cultivation of Glycyrrhiza uralensis farmland surface growth environment, reduce the cost and increase the yield and economic benefits, planter surface tillage, bulldozer cut root tillage and knife surface tillage were studied and compared with no tillage. The effects on main biological characteristics of soil moisture, compaction, surface root respiration, plant photosynthetic capacity, and G. uralensis height and yield were investigated. Comprehensive analysis showed that planter soil surface tillage and knife soil surface tillage were suitable mechanical tillage treatments which could improve soil environment of G. uralensis, increase production; planter soil surface tillage treatment could increase the yield by 7.43% and should be combined with early spring field fertilizers and mechanical weeding before middle or late May. Bulldozers surface tillage operation could cause serious damage to G. uralensis field, and was not recommended in application.
