Taking‘Jiashi’melon as material,the quality changes of ‘Jiashi’ melon with the mechanical refrigeration method under 0，1，2，3℃ at different storage periods(0,14,28 d) were observed.The results showed that the four storage temperatures under 14,28 d storage periods of ‘Jiashi’ melon breathing strength did not change significantly，different storage temperatures had no effect on fruit hardness and electrical conductivity.But the storage periods had a significant effect on hardness and electrical conductivity，the longer the storage periods，the lower of the hardness and reached significant level.Two factors (temperature and storage period) displayed ‘Jiashi’ melon in two aspects，the influence of solids content，sheet looks from temperatures and storage periods of one single factor，the content of solids had a significant change，but the two factors of solid content changes were the opposite，so when the two factors interact，it did not lead to solid content change.
