In order to eliminate the adverse soil factors affecting rice growth in the all time waterlogged paddy field in a two year period,effects of different soil amendments on rice yields,nutrient uptake and soil reductants were investigated.The results showed that among all the treatments,chicken manure and silicon calcium fertilizer produced much higher rice yields,increased by 11.3% and 10.7% in 2011 and 9.4% and 13.0% in 2012 than the control,respectively.Chicken manure,however,had 5.7% higher contents of soil total reductants than the control,and could bring a potential risk of harmful soil reductants if applied continuously.Just on the opposite,silicon calcium fertilizer effectively reduced soil reductants by 19.6% than the control.The response of rice yield to added lime appeared unstable in the two years,most likely due to the extreme weather encountered(severe drought in the first year and severe flooding in the second year).Thus,its effect on rice in this region needs further field experiments to substantiate.Zinc fertilizer behaved poor and unstable effect in this experiment.Therefore,silicon calcium fertilizer could be considered as an ideal soil amendment to use in the all time waterlogged paddy field for healthier growth and better yield of rice.
