我国厚皮甜瓜的产区一直局限于新疆、甘肃及内蒙等少数地区。其主要原因是因为厚度甜瓜起源于热带大陆性气候地区,在具备温暖、气温日较差大、日照充足,空气相对湿度低等环境条件的地区才能生长发育良好。由于目前产区多偏处边陲,产量有限,运输线太长,成熟期晚,其商品产量和品质远远不能满足国内外市场的需要,亟待扩大厚皮甜瓜的种植面积,开辟新的产区。华北地区属东亚大陆性季风气候。虽然夏秋多雨,但春季和夏初具有显著的大陆性气候的特点:日照充足、干旱少雨、温差大,如与盛产厚皮甜瓜的兰州相比,雨季前(多在7月中、下旬前)的生长期(4—7月),气象条件相近,完全有可能露地栽培厚皮甜瓜。而且华北和温较高,有利于生长(见表)。
The production area of muskmelon in China has been limited to a few areas such as Xinjiang, Gansu and Inner Mongolia. The main reason for this is that the muskmelon, which originated in tropical continental climates, grows and develops well in regions that are warmer, have poorer temperatures, have ample sunshine, and have relatively low air relative humidity. Due to the current multi-lateral edge of production areas, production is limited, the transport line is too long, late maturity, the output and quality of their products far can not meet the needs of domestic and foreign markets, the urgent need to expand the planting area of muskmelon, open up new producing areas . North China belongs to the East Asian continental monsoon climate. Although the summer and autumn rainy, but the spring and early summer has a significant continental climate characteristics: adequate sunshine, drought, temperature difference, such as rich melons and Lanzhou compared to the rainy season (mostly in mid-July before late) Of the growing season (April-July), weather conditions are similar, it is entirely possible to planted open-cut muskmelon. And the higher temperature in North China, is conducive to growth (see table).
