【摘要】 利用西湖疏浚的底泥废弃物，与化肥以 2∶ 8的配比混合，加工成有机无机复混肥。在蔬菜上施用结果表明，产量与等养分量的进口复合肥持平或略有增加，肥料成本降低，蔬菜中硝酸盐含量下降。更多还原

【Abstract】 An organic－ inorganic compound fertilizer with a ratio of two to eight was produced by mixing sediment of West Lake and chemical fertilizer. Another experiment with compound fertilizer applied on vegetable soil showed that yield with treatment of organic－ inorganic compound fertilizer was equal to or more than that with imported compound fertilizers under the condition with same nutrient level. In addition, the cost was lower and nitrate content in vegetable was reduced with the organic－ inorganic compound fertilizer applied.更多还原
