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.
