西瓜大果型品种,具有较大的增产潜力,相对容易获得高额产量。西瓜产量的构成公式是,亩(1亩=667平方米,下同)产=每亩株数×单株果数×单果平均重量。因为大果型西瓜栽培强调每株留一个果实,所以,其亩产实际取决于亩株数和单果平均重量两个因素。而对大果型品种来说,为防止田间郁蔽,应使叶面积系数保持在1.5～1.8,单位面积的株数因此而受到制约,故单果平均重量就成了决定单位面积产量的 Watermelon large fruit type, with greater yield potential, relatively easy to obtain high yield. Watermelon yield formula is, mu (1 mu = 667 square meters, the same below) = = per acre plant number of fruit × single fruit average weight. Because large fruit-type watermelon cultivation emphasizes leaving a fruit per plant, so its actual production depends on the number of acres and the average weight of two factors. For the large fruit varieties, in order to prevent the field Yu Yu, the leaf area coefficient should be maintained at 1.5 to 1.8, the number of units per unit area is therefore constrained, so the average weight of fruit has become the deciding yield per unit area
