摘　　要：以自育旱砂西瓜品种05-9和05-10为试材,测量果实生长发育期间的纵径、横径和发育天数,建立旱砂西瓜果实的生长模型,明确其相互间的变化规律。结果表明:旱砂西瓜果实纵径、横径与发育天数之间存在明显的多项式回归关系,且其生长发育数学模型为二次方程。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.
