Maturity depends melon cultivars growing season, it will be distributed when ripe muskmelon a strong aroma, textured surface rendering, fruit Yellowing of the skin and shiny, melon stems fall off naturally.

For short-term cold storage and direct sales of early varieties should be harvested at full maturity (physiological maturity), the melon with or without Guadi Pedicle can be.

The late-maturing varieties for refrigerated transport and long-term cold storage, cold storage can mature in the process, should be harvested harvest maturity, that is, Physiological maturity than two weeks to three weeks ahead of harvest. Harvest is appropriate scissors to cut and retain 2cm ~ 3cm of Guadi.

The late-maturing varieties after harvest should lay it in the sun to dry 4d ~ 5d, and regularly flip.

2.2 Quality

It should meet the national standards of quality.

It should be complete, fresh, clean; no smell, no pests; should have the skin color and the shape of the fruit of the species specific.

Precooling temperature should not be less than the recommended minimum temperature storage and refrigerated transport. Early maturing varieties should precooling 12h ~ 15h.

It should ensure that there is a tonne melon 80m3/h ~ 100m3/h air flow.

Melon cooled in refrigerated transport loading and unloading process should avoid temperature rises.
