摘　　要：在盆栽条件下,研究了不同叶面肥〔混合氨基酸、芸薹素内酯(BRs)、表面活性剂、微量元素〕配施对番茄生长及果实产量与品质的影响。结果表明:喷施叶面肥不仅能够显著增加番茄单株产量(比清水对照增产28.6%～85.7%),而且能够促进叶片对N、P、K的吸收;叶面喷施适宜浓度的BRs和营养物质能够显著促进番茄植株的生长,提高番茄叶片叶绿素含量及光合速率,提高果实VC、可溶性蛋白、可溶性糖含量,降低有机酸含量,使果实品质得到明显改善;在不同叶面肥处理中,无论是促进番茄植株生长还是提高果实产量与改善品质,均是营养元素与BRs的合理配合〔营养物质(混合氨基酸+B+KH2PO4)+BRs+表面活性剂+微量元素(Fe、Cu、Mn、Zn)〕能达到最理想的效果。A pot experiment was carried out to study the effect of different foliar fertilizer on the growth,yield and quality of tomato. The results obtained were listed as following： application of different foliar fertilizers could not only increase tomato yield 28.6 % - 85.7 % higher than that of the control,but also enable the plant to rapidly absorb N, P and K through its leaves, thus markedly increasing their contents in the plants. Foliar applications of suitable concentration of BRs and nutrient substance significantly promoted plant growth,enhanced chlorophyll content and net photosynthetic rate of tomato leaves,improved the contents of VC, soluble sugar and protein and decreased the content of organic acid of tomato,thus improving the fruit quality. Among the different combinations of foliar fertilizers, the rational mixture of suitable concentration of nutrient substance with BRs bad the most optimum results in stimulating plant growth and increasing yield and improving fruit quality.
