近几年来,我省不少地区相继发展西瓜种植。榕江西瓜汁甜味美,皮薄瓤红,堪称上品,远销省内外,经济效益显著。贵阳近郊花溪、青岩等地也多种西瓜。但有的地区西瓜质量好,经济效益显著,有的则质差,经济效益不甚显著。其原因固然与品种、土壤、种植技术、施肥和管理水平有关,但与气候条件关系也很大。西瓜原产于非洲,喜温好光,并要求有一定的水分保证。西瓜生长的适宜温度为18～32℃,能耐高温,在35～40℃仍可进行较强的同化作用;但不耐低温,15℃时,生长缓慢,10℃或以下时则停止生长。种子发芽的温度为15℃,但出苗缓慢,开花坐果期下限温度为18℃,适宜温度为25～28℃,温度低于20℃
In recent years, many areas in our province have successively developed watermelon cultivation. Rongjiang watermelon juice sweet beauty, thin thin red, called the top grade, sold outside the province, significant economic benefits. Guiyang suburbs Huaxi, Qingyan and other places also a variety of watermelon. However, some areas have good watermelon quality, significant economic benefits, and others are poor in quality with less obvious economic benefits. The reason is not only related to variety, soil, planting technology, fertilization and management, but also to the climatic conditions. Watermelon native to Africa, hi warm, and require a certain amount of moisture. Watermelon growth suitable temperature is 18 ~ 32 ℃, high temperature, 35 ~ 40 ℃ can still be a strong assimilation; but not resistant to low temperature, 15 ℃, slow growth, 10 ℃ or below, then stop growing. Seed germination temperature is 15 ℃, but the emergence is slow, flowering set the minimum temperature of 18 ℃, the appropriate temperature is 25 ~ 28 ℃, the temperature is below 20 ℃
