本试验以白菜为试验材料，清水为对照探索了5种水溶肥配方对白菜品质及土壤性质的影响。结果表明，与对照相比，配方4处理的白菜Vc含量最多，配方1次之，分别较对照增加了210%、193%，硝酸盐含量除配方3和配方5外，其他处理均小于432 mg/kg，在安全范围内；5种水溶肥均能在一定程度上改善土壤pH值和电导率，配方1土壤碱解氮和有效磷含量最高，分别为327.8 mg/kg和118.23 mg/kg，参照菜园土壤有效养分丰缺状况的分级标准，土壤氮、磷含量过高，可能会对周边的水环境造成污染。

In this experiment,with clear water as a contrast,the effects of five kinds of water-solu-ble fertilizer formulas on cabbage quality and soil properties were explored. The results showed that compared with the contrast,Vc content in cabbage cultured by fertilizer formula No. 4 was the high-est,followed by that of formula No. 1,respectively higher than the contrast by 210% and 193%. The nitrate contents in cabbage by other treatments,except Formula No. 3 and formula No. 5,were less than 432 mg/kg,in a safe range. Five kinds of water-soluble fertilizer can improve soil pH and conductivity to some extent. Soils treated by Formula No. 1 contained the highest nitrogen and phos-phorus,where were 327. 8 mg/kg and 118. 23 mg/kg respectively. As referring to Vegetable Soil Fertility,too high nitrogen and phosphorus contents in soil may cause pollution to the surrounding water.
