A pot experiment was carried out to study dynamic variations of biomass accumulation of Chinese cabbage and N, P, K nutrient uptake at different growth stages as affected by various fertilizations under the alluvial vegetable soil. The results showed the substance auumulation of cabbage mainly appears in the middle vigorous growth period from the 30th to 45th days after transplanting. The absorbed nutrient rates for Chinese cabbage were: N, P2O5、 K2O 818.6, 87.1 、 713.3 g/pot with the ratio of 1 : 0.23 : 1.06, respectively, during the whol...
