摘　　要：In order to explore the effects of amino acid foliar fertilizer on the yield and quality of different vegetables, we tested the spraying of an amino acid foliar fertilizer(Wanfeng 2) onto the leaves of cucumbers, eggplants and water spinach through contrast experiment in a greenhouse. The results showed that the yield increments of amino acid foliar fertilizer treatments in cucumbers, eggplants and water spinach were 11.57%, 4.43% and 12.41% respectively, and the output-input ratios were 64.52 ∶ 1, 53.31 ∶ 1 and 55.14 ∶ 1 respectively. Amino acid foliar fertilizer can influence the quality of greenhouse vegetables. The total sugar content of the cucumbers, eggplants, and water spinach significantly increased by 12.00%, 22.30%and 12.10% respectively. The vitamin C content increased by 4.76%, 24.80%, and10.90% respectively compared with the control. In conclusion, the spraying of amino acid foliar fertilizer could improve the yield and the nutritive quality of vegetables such as cucumbers, eggplants and water spinach.为了探明氨基酸叶面肥在不同蔬菜上的应用效果,通过对比试验,研究了喷施氨基酸叶面肥对大棚黄瓜、茄子、空心菜产量和品质的影响。结果表明:氨基酸叶面肥对黄瓜、茄子、空心菜均有增产作用,增产幅度分别为11.57%、4.43%和12.41%,产投比分别为64.52∶1、53.31∶1、 55.14∶1,增产增收效果显著。氨基酸叶面肥对蔬菜品质具有影响,可显著增加黄瓜、茄子、空心菜的总糖含量,分别较对照增加12.00%、22.30%、12.10%,维生素C含量较对照的增加幅度为4.76%、24.80%、10.90%;喷施氨基酸叶面肥有利于提高黄瓜、茄子、空心菜等蔬菜的产量,提升其营养品质并改善口感。
