| Abstract: |
| Different tillage methods in the South of Maowusu Sandlot farmland was tested,results show:tillage methods affect soil physical-chemical quality and corn yield.contracting tillage method,No-tillage surface soil's,sustaining water and fertilizer ability decreases,bulk density becomes larger and soil organism accumulates,the ripe is about for 5～10 days later,and it's more likely to suffer the frost hurt.In the tillage and cladding method,the soil temperature in early terms can be raised,obviously,the soil's ability of sustaining water and nutrient becomes better.By cross-tillage and cladding method,yield can be increased by 13.74%;but by no-tillage conserve plant,yield will be decreased by 1.66%,then,economic efficiency of no-tillage is to be considerable. |
