In order to improve nutrient management of vegetable production, further achievement of high yield and good quality vegetable production as well as sustainable development. Field experiment was conducted to study the effects of controlled release compound fertilizers (CRFs) on yield, nutrition absorption and quality of cucumber. Compared to conventional fertilization strategy, NPK application rate of CRFs was reduced 50%, in which 20% was mixed with substratum when raised seedling and the other 80% was banding application when transplanted. Results showed that seedling height and leaf area with CRFs increased by 13% and 12% respectively in comparison to conventional fertilization, meanwhile, cucumber yield with CRFs increased 14.1%, N, P and K absorption increased by 17.0%, 11.1% and 14.8% respectively, nitrate content of cucumber decreased 11.9%.
