Abstract:: With ‘05-9’ and ‘05-10’ watermelon cultivars as test material in gravel-mulched field,the growth model for watermelon fruit was established through determining the indexes such as the vertical diameter,transverse diameter and developing days of the fruits during the growth and development of watermelon and the change law among the indexes was made clear.The results showed that the vertical diameter，transverse diameter and developing days of the fruits were a polynomial regression relation，and their growth course mathematical models all were the quadratic equations.
