Abstract: To study the effect of chemical fertilizer reduction and salinization on watermelon output and quality, correlation experiment was done in 5 years canopy with 3 years of watermelon monoculture in Tangzhen agriculture demonstration base in Pudong zone of Shanghai city.The results showed that applying more organic fertilizer and less chemical fertilizer was feasible.Applying enough basic fertilizer and no chemical fertilizer in fruit growth period combined with water replacing fertilizer was also feasible.Watermelon quantity on individual plant, weight of individual fruit, yield and center sugar concentration on the reduction treatment area were better than that of routine area.All thess showed the Ndosage could be reduced greatly.
