| Abstract: |
| To solve problems of serious soil compaction and shallow plow layer depth in arid areas, a field experiment was carried out in Nuanquan Farm of Ningxia in 2021. The traditional rotary tillage was used as the control (CK). Different Fenlong cultivation depths of 30 cm (FL30), 40 cm (FL40), 50 cm (FL50) and 60 cm (FL60) were set to explore the effects of Fenlong cultivation on key physical properties of maize soil. The results showed that compared with traditional rotary tillage, Fenlong cultivation effectively reduced soil bulk density and improve soil porosity. The bulk density of surface soil (0~20 cm) in FL50 treatment decreased by 11.55%, and the porosity increased by 12.17%. The bulk density of middle soil (20~40 cm) in FL40 treatment decreased by 8.57%, and the porosity increased by 9.14%. The bulk density of deep soil (40~60 cm) in FL60 treatment decreased by 11.61%, and the porosity increased by 12.75%. Fenlong cultivation had a significant indigenous effect on soil water storage at different growth stages of maize. Soil water storage FL40 treatment increased by 24.86%, and the number of soils mechanically stable aggregates (0.25~5 mm) increased by 9.63%. Compared with traditional rotary tillage, Fenlong cultivation achieved the effect of loosening soil and improved soil water storage and soil moisture retention capacity. Fenlong cultivation increased grain yield by improving the growth conditions and soil environment of maize,in which the FL60, FL50 and FL30 treatment increased the yield by 57.14%, 15.48% and 8.79% respectively, compared with the CK treatment. The conclusion of this study provides a theoretical basis for improving the years of soil compaction and the sustainable utilization of water and soil resources in arid areas. |
