通过向水中施入不同量的复合肥,根据竹叶菜生长的形态指标和生理指标,研究不同复合肥浓度对竹叶菜生长的影响。结果表明,处理T_4(复合肥浓度为1.5 g/L)的竹叶菜长势旺盛、产量高,叶绿素含量适中,硝酸盐含量未超过国家规定的限量值,亚硝酸盐含量低,符合国家绿色蔬菜的标准。因此处理T_4是竹叶菜水培的适宜复合肥用量。
By applying different amounts of compound fertilizer to water, the effects of different compound fertilizers on the growth of bamboo leaves were studied according to the morphological and physiological indexes of the growth of bamboo leaves. The results showed that the treatment of T_4 (compound fertilizer concentration of 1.5 g / L) of bamboo growing vigorously, high yield, moderate chlorophyll content, nitrate content does not exceed the national limit, nitrite content is low, in line with the national green vegetables Standard. Therefore, the treatment of T_4 is suitable for bamboo shoots hydroponic fertilizer dosage.
