摘  要:
以意大利全年耐抽薹生菜为试材,研究了营养液中EDTA-Fe、柠檬酸铁、硫酸亚铁3种不同形态铁肥对生菜生长和品质的影响。结果表明:生菜施用铁肥能明显提高其产量和品质。其中EDTA-Fe和柠檬酸铁2种形态的铁肥较易被生菜吸收利用,可促进生菜的生长和品质的提高,其株高、叶面积、叶色、含水量均优于不处理植株(CK),且维生素C含量、蛋白质含量、可溶性糖含量、脯氨酸含量均较高。3种不同形态铁肥相比,EDTA-Fe效果最好,柠檬酸铁次之,硫酸亚铁不利于生菜吸收利用,有效性较差。

摘  要:
Taking the annual bolting lettuce as material,the effect of three kinds of ferric fertilizer in the nutrient solution of soilless on growth and quality of lettuce were studied.The results showed that applying iron fertilizer could obviously increase the yield and quality of lettue.EDTA-Fe and ferric citrate were more vulnerable to promote absorption and utilization of lettuce,they improved the growth and quality of lettuce.The height,leaf area,leaf color,water content of lettuce were better than CK,the vitamin C content,protein content,soluble sugar content,proline content also were higher than CK.The effect of EDTA-Fe was the best,ferric citrate was better.Ferrous sulfate was not conducive to the absorption and utilization of lettuce,poor validity.
