摘　　要：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。We studied the effects of different concentrations of compound fertilizer acting on water spinach growth according to morphological and physiological indexes under water planting condition.The results showed that,for treatment T4（with compound fertilizer concentration of 1.5 g/L）,the water spinach grew strongly with high yield and moderate content of chlorophyll,in addition,nitrate content did not exceed the maximum limit value prescribed by our country.Because of the low content of nitrite,the water spinach products met the national standard of green vegetables.Therefore treatment T_4 with compound fertilizer concentration of 1.5 g/L was suitable for water planting of water spinach.
