Using Cucumis melo L.CV Hetao as subject, carries on 35℃, 45℃and 55℃the hot water separately soaks 15min, 1%CaCl2 and 5%CaCl2 soaks 15min and 45℃the hot water soaks the 15min processing including 1%CaCl2 and 5%CaCl2, after the processingunder the room temperature stores.The paper aims to study the effect of the heat treatment, calcium treatment and heat-calcium treatment on the postharves phphysiology and hoard effect of Cucumis melo L.CV Hetao, stores time as the Cucumis melo L.CV Hetao provides the new technology. The result showed:(1) Under the normal temperature storage conditions, 35℃the heat treatment picks after the Cucumis melo L.CV Hetao the postharves phphysiology and hoard effect not to be obvious. 45℃the heat treatment and 55℃the heat treatment picks after the Cucumis melo L.CV Hetao the postharves phphysiology and hoard effect to be remarkable, will compare 45℃the heat treatment with the comparison and 55℃the heat treatment the Cucumis melo L.CV Hetao breath jump will have postponed 6d, made the storage period to lengthen 6d; But 55℃the heat treatment caused the Cucumis melo L.CV Hetao to have the hot injury, 45℃the heat treatment Cucumis melo L.CV Hetao stored the effect to be good, compared not obvious difference before the storing Cucumis melo L.CV Hetao's quality; Therefore this research indicated that is best by 45℃the heat treatment effect.(2) 45℃the heat treatment picks after the different maturity's Cucumis melo L.CV Hetao the postharves phphysiology and hoard effect to be different, nine mature Cucumis melo L.CV Hetao store the effect to surpass eight mature Cucumis melo L.CV Hetao, displays in nine mature Cucumis melo L.CV Hetao in firmness , soluble solid content, titratable acid content and depraved rate and so on stores the quality aspect to compared to eight mature Cucumis melo L.CV Hetao good. Therefore this research nine mature Cucumis melo L.CV Hetao should for the best recovery time.(3) Pure (1%CaCl2,5%CaCl2) calcium treatment after the Cucumis melo L.CV Hetao's respiration rate and ethylene production and so on picks the postharves phphysiology and hoard effect is not big, but regarding Cucumis melo L.CV Hetao's degree of firmness and menbrane relative permeability, depraved rate is remarkable. Different density's CaCl2 in Cucumis melo L.CV Hetao's degree of firmness and menbrane relative permeability, depraved rate function effects is different, the 5%CaCl2 treatment function effect surpasses the 1%CaCl2 treatment.The heat and calcium-treatment picks after the Cucumis melo L.CV Hetao the postharves phphysiology and hoard effect to surpass pure calcium treatment. Will compare the heat and calcium-treatment to gather calcium treatment also the Cucumis melo L.CV Hetao breath jump to postpone 6d, the storage period lengthened 6d; And in Cucumis melo L.CV Hetao's firmness and menbrane relative permeability, depraved rate must surpass the pure heat treatment. And heat and calcium-treatment(5%) in Cucumis melo L.CV Hetao's firmness and menbrane relative permeability, depraved rate function effects must surpass heat and calcium-treatment(1%), therefore heat and calcium-treatment(5%) effect is best.
