Three controled release fertilizers, the ration of N-P2O5-K2O which were 14.25-14.25-14.25、13.5-13.5-13.5 and 12.75-12.75-12.75, coated with fly ash and organic agglomerant, were made of common compound fertilizer (N-P2O5-K2O：15-15-15). A field experiment was conducted to study the effect of coated release fertilizers on physiological characteristics, yield and quality of Chinese cabbage. The result showed that the coated release fertilizers could increase the leaf chlorophyll content, photosynthetic rate , transpiration rate and stome conductance and decrease the leaf stomata limitation at same fertilizer level. Comparing to common compound fertilizer, the coated release fertilizers increased the plant height 0.13-1.00cm, diameter 0.01-2.26cm, length 0.77-1.90cm, wide -0.63-3.47cm. At the same time,. the coated fertilizers improved the per plant weight of Chinese cabbage 10.1%-33.3%.In addition, the coated release fertilizers decreased the NO3--N, organic acid contents, and improved the soluble sugar, sugar-acid ratio and Vc contents of the leaf at the harvest stage.
