Abstract:
The results of five-year test of no-tillage with maize straw mulching suggested that soil moisture content increase by 5.56% to 17.0% in treatment of NTMS(no-tillage with maize straw) compared with other treatments,soil bulk density decrease(0-10 cm soil layer) by 9.35% to 10.9% compared with other treatments,soil total porosity(10-20 cm soil layer)increase by 13.80% compared with NTN(no-till without straw mulching),soil water stable aggregate(≥0.25 mm,0-10 cm soil layer) increase by 104.5% compared with TN(tillage with no straw return).Also the results suggested that soil total nitrogen content in treatment of NTMS increase by 10.6% to 15.8% compared with other treatments,soil alkali-hydrolyzadle nitrogen content increase by 23.3% compared with TN(tillage with no straw return),and soil organic matter content increase by 29.0% to 33.8% compared with other treatments in 0-20 cm soil layer.Although the treatment of NTMS improved soil physicochemical properties,the significant higher yield of winter wheat corresponded with the improved soil was not found in the test.The further study on the question about how to increase winter wheat output in NTMS need to be carried out to exert its advantage sufficiently,then the soil sustainable use of land would be realized.
