| 摘 要： | 在上海浦东新区唐镇农业示范基地3年西瓜重茬的5年棚内进行了西瓜氮肥减量与盐渍化等的相关试验，以研究对西瓜产量、品质等的影响。试验表明在一定的肥力基础上，增施有机肥，氮肥减量是可行的，一次施足基肥，膨果期不再施肥，以水吊肥也是可行的。氮肥减量处理区西瓜最终在单株结瓜数、单瓜重、每公顷产量及中心糖度各指标上，均好于常规施肥处理区，表明氮肥用量可明显减下来。

| 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. |
