长期施用含氯化肥对蔬菜产量和品质影响的研究

Study on Effects of Long-term Application of Chloride-contained Fertilizer on Vegetable Yields and Qualities

经过11年连续施用含氯化肥(氯化铵),各种植21茬不同蔬菜施用氯化铵的长期定位试验表明:在等氮、磷、钾养分条件下,氯化铵的施用对蔬菜的产量未产生不良影响。从蔬菜品质看,在施用等量养分情况下,长期施用氯化铵对蔬菜作物的含糖量未产生不良影响,对大多数蔬菜来说,含糖量有增加的趋势,而施用氯化铵较施用硫酸铵处理的Vc含量略有下降。

The long-term experiment for the 11-year continuous application of ammonium chloride to 21 vegetable crops showed that there were no bad effects on the yield and sugar content by applying ammonium chloride under the equivalent N- P- K fertilizers used. For the most vegetables- sugar contents trended towards increasing- but the Vc contents were slightly decreased under the application of ammonium chloride compared with ammonium sulfate application.
