Influences of Fertilization on Carbon Phyto-fixation in Rice Cropping System
A field experiment was conducted in south Taihu Lake Basin, Zhejiang Province, China, to investigate the effects of nitrogen, phosphorus and potassium fertilization on biomass and carbon accumulation in rice cropping system. The results indicated that integrated fertilization with appropriate doses of nitrogen, phosphorus and potassium could significantly (P<0.05) increase both biomass of carbon accumulation in rice plants. The potential of carbon assimilation in rice cropping system in the experimental she was higher than the mean in the world. The appropriate rates of nitrogen, phosphorus and potassium were recommended as 225 N kg/ha, 60 P2O5 kg/ha and 90 K2O kg/ha, respectively. The ratio of total carbon accumulation to air-dried grain can be used as an index of 1.01 to estimate the capacity of carbon phyto-fixation in rice cropping system.
