在西瓜长大过程中,着地一面因长期见不到阳光,温度也较其它部位低,因此,发育缓慢,瓜皮呈黄白色,皮厚瓤硬味淡,品质较差;而上部果面因受光均匀,温度条件较好,果皮颜色鲜艳,皮薄瓤脆,汁多味甜,所以会发生一个西瓜颜色差别大、瓜瓤品质差异也大的现象。据试验,让西瓜翻身,不仅可消除这种现象,而且能使西瓜成熟提早,品质更优,卖出高价钱。西瓜翻身就是在西瓜膨瓜后期要进行翻瓜。方法是每隔7—8天翻动一次,可翻二次,将西瓜在原地顺着一个方向翻转180度,使整个瓜光温均匀,发育成熟一致。在翻瓜时,要注意三点:一是, In the process of growing up watermelons, the ground side of the sun because of long-term see, the temperature is lower than other parts, therefore, slow development, pale yellow skin, thin skin, hard and light taste, poor quality; and the upper fruit surface cause Light uniform, better temperature conditions, peel color bright, thin crisp skin, juicy sweet, so there will be a big difference between watermelon color, melon 瓤 quality differences are also large phenomenon. According to the test, let the watermelon stand up, not only can eliminate this phenomenon, but also make the watermelon mature earlier, better quality, sell high prices. Watermelon stand up is in the late melon watermelon melon melons. Method is to flip every 7-8 days once, you can turn twice, the watermelon in the same place in the direction of a flip 180 degrees, the entire melon light temperature, mature and consistent development. In turning melon, pay attention to three points: First,
