With the gradual expanding of ginger cultivation area and the improving of yield level，the dry matter accumulation and nutrient absorption of ginger under high-yield cultivation mode were clarified in this study，which could be an important basis for high-yield and high-efficiency cultivation of ginger，and provide theoretical support for efficient utilization of chemical fertilizer in sustainable production of ginger. Through optimizing fertilization management of ginger，continuous sampling and observation of plants at key growth stages under facility and open-field modes were carried out to analyze the absorption and accumulation rules and characteristics of dry matter and nitrogen，phosphorus and potassium nutrients under different modes. The dry matter accumulation of ginger under the facility and open-field during the whole growth period was generally showed as the “S” type. The rhizome expanding stage was the main period for the dry matter accumulation of ginger. At the harvest，the dry matter accumulation per plant of ginger in facility and open-field ranged from 233.6 to 276.4 g and 211.2 to 238.4 g，respectively，and the dry matter accumulation of ginger tuber accounted for 53.64%-54.82% and 42.53%-45.20% of that of the whole plant，respectively. The nitrogen absorption of facility and open-field ginger mainly concentrated in the root and stem expansion stage，accounting for 38.72%-44.78% and 46.37-46.76%，respectively. The phosphorus uptake in each growth period showed a slight increase trend，and the peaks of phosphorus uptake in the optimized fertilization occurred at transition period，which was 33.88% and 28.45%，respectively. The absorption of potassium was increased linearly in a fluctuating pattern，and the absorption peak appeared in both seedling and root expansion stages. The proportion of potassium uptake in the two growth stages was 25.27%-26.14% and 28.58%-32.40%，respectively. The dry matter accumulation characteristics were S-shaped under both facility and open-field high yield modes. When ginger was harvested，the ratio of nitrogen，phosphorus and potassium uptake per plant ranged from 2.4-3.0∶1.0∶6.3-6.7 and 2.9-3.2∶1.0∶6.8 -7.3，respectively. Under the optimized fertilization technique，the N，P2O5 and K2O uptake of 1000 kg ginger tuber in facility and open-field were 2.41，1.01，6.82，and 2.45，0.77，5.61 kg，respectively.
