摘要

摘要比较了芦笋幼苗在7种不同硝铵比(NO3 -: NH4 +)溶液中的生长情况。N以NO3 -形式存在的比例为100% ~ 50%。芦笋在NO3 -为主的溶液中生长最好，在NO3 -: NH4 +的混合物中，NH4 +的氮含量为17-40%，笋根生长最快。100% NO3 -或50% NH4 +均可显著降低生长。

Effect of nitrate:Ammonium ratios on growth of asparagus seedlings in sand culture

Abstract Growth of asparagus seedlings when grown in seven solutions with varying nitrate: ammonium ratios (NO3 -: NH4 +) was compared. The proportion of N present as NO3 - ranged from 100% to 50%. Asparagus grew best in NO3 - dominated solutions with maximum shoot and root growth occurring with NO3 -: NH4 + mixtures containing nitrogen as 17–40% NH4 +. Significant reductions in growth occurred with either 100% NO3 - or 50% NH4 +.
