The experiment was carried out about continuous tillage in spring and autumn in salinization meadow soil,in order to clarify the effect of tillage period on soil physical and chemical characteristics and rice yield.The result showed that the water content and bulk density was decreased when tillage in autumn,soil water content was decreased by 10.07%,bulk density was decreased by 0.02 g·cm-3 in 0~10 cm layer.Compared with tillage in spring,the average value of soil available nitrogen,available phosphorus and available potassium were increased by 29.30%,43.77% and 24.06%,ammonium nitrogen was 7.94 mg·kg-1 higher after flooding cultivation,exchangeable sodium ion was increased by 11.16%~129.72%,and pH value was decreased by 0.10~0.36.Autumn tillage improved root activity,promoted nutrient uptake of rice kernels and the accumulated content of nitrogen,phosphorus,and potassium was increased by 4.51,2.49 and 1.03 kg·hm-2,the yield was increased by 1.03% and 22.61% in the first and second year,the average was 11.82%.In summary,in salinization meadow soil area,the soil physical and chemical properties and rice yield were better when tillage in autumn than that in spring.
