Abstract: Effects of peat and weathered coal on activity of rice root system and its nutritional absorption were studied by pot experiment.The results showed that adding peat and weathered coal improved α-naphthyl amine oxidizing activity of root system during the different growing phases of rice,ameliorated the nutrient supplying of saline-alkali soil,enhanced the yield of rice,and increased the nutritional absorption of N,P2O5、K2O,CaO,and MgO by rice.To increase productivity,peat is better than the same quantity of weathered coal.
