Title: Effects of Nitrogen Concentrations and Different Nitrogen Forms on Nitrate Content and Nitrate Reductase of Chinese Chive
Abstract: Effects of nitrogen concentrations and different nitrogen forms on nitrate content and nitrate reductase of Han zhong Chinese chive in hydroponics was tested with hydroponics.The results showed that with increase of nitrogen concentrations,nitrate content and nitrate reductase of the leaf gradually rose.With the increase of NH_4~+,nitrate content and nitrate reductase of the leaf gradually declined;According to comprehensive measure index of nitrate content,the suitable content of nitrogen was 4~8 mmol/L,the suitable rate of NO_3~-←NH_4~+ was 1←3~0←4 for Han zhong Chinese chive。
