Abstract:
      A field plot randomized block experiment was conducted to study the effects of different tillage practiceson the ferrous iron of soil,rice yield components and rice yield in cold waterlogged paddy field. The results indicatedthat different tillage practices had different effects on the ferrous iron of soil,various biological traits of rice and yieldcomponents. The ferrous iron reduced by 27.97%-44.86% with different processing methods. The maximum reductionwas obtained in fewer-tillage processing by 393.35 mg/kg,and the treatment with paddy-upland rotation followed by451.88 mg/kg. Compared with farmer's practice,the practice of fewer-tillage led to the highest yield with 7 790 kg/hm2 andthe growth rate was 4.55%. The treatment with ridge tillage followed by 7 764 mg/kg and the growth rate was 4.51%.
