摘要:
以“791宽叶雪韭”为试材，在完全水培条件下，采用北京市农林科学院蔬菜研究中心研发的新型水培系统进行水培试验，研究了NO3-∶NH4+为12∶0、8∶4、6∶6、4∶8、0∶12五个硝、铵配比营养液对水培韭菜生长生理指标及产量和品质的影响，以期探寻适用于水培韭菜生长的硝、铵配比。结果表明：以产量及生长发育为分析目标，NO3-∶NH4+为8∶4处理适用于水培韭菜生产；以营养品质作为分析目标，NO3-∶NH4+为6∶6和4∶8处理其维生素C含量较高且有较低的硝酸盐累积情况，但这2个处理生长量过低。综合分析，适用于水培韭菜的营养液NO3-∶NH4+为8∶4。
Abstract:
Taking ‘791 kuanyexuejiu’as the test material，under the condition of completely nutrient solution hydroponics，the hydroponic experiment was taken by using a new type of hydroponic system developed by Vegetable Research Center of Beijing Academy of Agriculture and Forestry Sciences，the effects of five kinds of ratios of NO3-and NH4+ （12∶0，8∶4，6∶6，4∶8，0∶12）on growth and physiological indexes and quality of hydroponic Allium tuberosum were studied，in order to define the proper ratios of NO3-and NH4+suitable for hydroponic Allium tuberosum.The results showed that taking the yield and growth and development as analysis of element，the ratio of NO3-and NH4+ at 8∶4 treatment was suitable for hydroponic Allium tuberosum,6∶6 and 4∶8 treatments had the higher content of vitamin C and the lower content of NO3-,but these two treatments both had the lower yield.Comprehensive analysis,the suitable ratio of NO3-and NH4+ was 8∶4 for hydroponic Allium tuberosum.
