| Abstract: |
| Effects of long-term zero-tillage on soil physiochemical properties, enzyme activities and their correlativity
were studied by using traditional tillage and long-temm zero tllage cinnamon soil in Chenghuang experimental wheat field, which is located in Yaodu District of Linfen City in Shanxi Province. The result indicated that:compared with tra-ditional tllage soil, ①the content of organic matter of zerotillage soil (0~20 cm) of 17 and 12 years increased by 35.7% and 26.7% respectively; ②in the layer of 0~20 cm，the content of total N, total P and total K of zero tllale soil of 17 years increased by 20.1%，22. 8% and 12.6% respectively, while the content of total N and total K of zero-tillage soil of 12 years increased by 11.8% and 21.5% respectively; ③the content of available K, available P and available N of zerotillage soil of 17 and 12 years increased significantly; ④activities of catalase, urease and invertase of the zero tillage soil were significantly above the traditional tillage soil in 0~20 cm and 20~40 cm layers. So long temm zero-tillage would not only improve soil enzymatic activity， but also improve soil fertility significantly. |
