摘要:

以丽春(Solanum lycopersicum L.cv.Lichun)为实验材料,研究了3%纳米材料营养液喷施及拌肥施肥两种处理,对番茄果实品质的影响。结果表明,喷施、拌肥两种处理显著提高果实糖酸比及可溶性糖、VC、总酚、类黄酮含量,但对还原糖含量无明显影响,可滴定酸含量较对照分别提高20.4%、22.2%,可溶性蛋白含量提高37%、30%,拌肥处理果实番茄红素含量提高了1.9倍。气相色谱-质谱(GC-MS)检测果实中芳香物质,表明喷施处理后,顺-3-己烯醛、反-2-己烯、6-甲基-5-庚烯-2-酮、水杨酸甲酯含量提高,酯酮物质增加。拌肥处理果实芳香物质顺-3-己烯醛、反-2-己烯、2反、4反一己二烯醛、水杨酸甲酯含量提高,促进了长链烷烃的释放。纳米材料营养液采前处理可以显著提高番茄果实品质,且拌肥处理作用优于喷施处理。

Abstract:

Tomato fruit (Solanum lycopersicum L.cy.lichun) were used to study the effect of treatment spraying branches with 3% nanometer nutrient solution and fertilizing treatment mixing 3% nanometer nutrient significantly improved the titratable acid content by 20.4% and the soluble protein content by 37%.Fertilizing treatment significantly improved the titratable acid content by 22.2%, the soluble protein content by 30% and the lycopene content 1.9 times.Two treatment also significantly improved the content of sugar-acid ratio, total soluble sugar , Vitamin C, total phenols and flavonoids, but no significantly effect on reducing sugar content. Tomato aromatic substance detecting by GC-MS, showed that two treatments increased (Z)-3-Hexenal, (E)-2-Hexenal, 6-methyl-5-Hepten-2-one,Methyl salicylate, Ketone and esters increased by spraying treatment and Long Chain Alkane, and (E,E)-2,4-Hexadienal increased by fertilizing treatment is effective than spraying treatment.
