福泰莱含氨基酸水溶性肥在生菜上的应用效果研究

Study on the Effect of Futailai Water-soluble Amino Acids Fertilizer on Lettuce

选用生菜为试验材料,研究叶面喷施不同浓度福泰莱含氨基酸水溶性肥对生菜生长的影响。试验设6个处理,即含氨基酸水溶性肥料分别稀释倍数为0(CK)、100(T_1)、500(T_2)、1 000(T_3)、1 500(T_4)、2 000(T_5)。结果表明:与对照相比,叶面喷施含氨基酸水溶性肥可以提高产量,增加叶面积。其中T_4组(稀释1 500倍)效果最为明显,地上部鲜质量、干质量比对照组分别增加19.72%和92.44%;含氨基酸水溶性肥料可以增加生菜可溶性固形物含量,其中T3组(稀释1 000倍)增加效果最明显,与对照组相比增加17.92%。综合试验结果,生菜叶面喷施福泰莱含氨基酸水溶性肥最适浓度为稀释1 500倍。

In order to study the effects of water-soluble amino acids foliar fertilizer with different concentrations on the growth and quality of lettuce, the experiment designed 6 treatments, which set up different diluted times 0 （CK）, 100（T0, 500（T2）, 1 000（W3）, 1 500（T4）, and 2 000 （Ts） of fertilizer. The results showed that water-soluble amino acids could promote the growth of lettuce, which increased yield and leaf area. The yield of T4 group （diluted 1 500 times） was the highest, fresh weight and dry weight increased by 19.72% and 92.44% than the control, respectively. Compared with the control group, the water- soluble amino acids fertilizer could increase the soluble solid content of lettuce and T3 group （diluted 1 000 times） increased by 17.92% than the control group. Comprehensive each index, the optimum concentration for lettuce growth was diluted for 1 500 times.
