Abstract：In the randomized block experiment，there were 5 treatments，including no fertilization（CK），
conventional fertilization（100CF），100% conventional fertilization + bio-organic fertilizer（100CF+SF），
90% conventional fertilizer + bio-organic fertilizer（90CF+SF），and 80% conventional fertilizer + bio-organic
fertilizer（80CF+SF）．This experiment studied the eff ects of partial substitution of chemical fertilizer by bioorganic
fertilizer on cucumber yield，output input ratio，quality，nutrient distribution and fertilizer utilization
rate．The results showed that the distribution rates of N，P and K in diff erent parts of plant were diff erent，
that in stem and leaf were the highest，followed by fruit and those in root was the least．Compared with the
treatment of conventional application of chemical fertilizer alone，reducing 20% of the common chemical
fertilizer + applying 400 kg · （667 m2） -1 bio-organic fertilizer had the better effect．Thus，the single fruit
weight and cucumber yield were increased，nitrate content of cucumber fruit was reduced，contents of soluble
sugar and soluble protein were increased，and product quality was improved，utilization rates of nitrogen，
phosphorus and potassium were all enhanced．
