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.
