Abstract:
Taking three varieties of  Allium tuberosum Rottler‘Saisong’,‘Pingjiu 4’,‘Pingjiu 8’as materials,the effects of different nitrate and ammonium ratio on growth and chlorophyll content of  Allium tuberosum Rottler investigated under hydroponics on 14 mmol/L nitrogen level.The results showed that with proportion of the NO3-N increased,the leaf length,leaf width,single leaf weight and chlorophyll content increased then decreased in the three varieties.The NO3-N and NH4+N treatment of 50∶50 promoted the growth and was more suitable for Allium tuberosum Rottler growth.
