Study on Soil Improvement and Thickening and Seedling Preservation Technology of Deep Rotary Tillage
Long-term use of surface tillage(10~15 cm)can easily lead to shallow soil layer and form obvious plow bottom,reduce soil moisture retention and fertilizer retention ability,and affect the growth and development of maize roots.Therefore,in 2023,deep rotary tillage was carried out in Fumeng County to improve soil densification technology research,the results show that:The planting density of 3 500 plants/667 m2,deep rotation tillage of 30~35 cm and organic fertilizer application can increase soil topsoil thickness,optimize soil structure and yield composition,and then improve crop yield and water use efficiency,which is the appropriate planting technology model in western Liaoning.
