西瓜具有喜高温、干燥和多光照等特性。据前人研究,西瓜种子发芽的最低温度为18～20℃,最适温度25～30℃。其根为好气性,在通气不良的土壤里,发育不良,雨水多时根受伤害。目前我国西瓜生产栽培和种子检验工作中,人们常常发现西瓜种子发芽时,一旦水分高,则很少发芽或发芽困难,而影响西瓜均播种成苗和测定种子发芽率的准确性。为了探讨西瓜种子发芽的水分特性,我们于1986年6月份,采用不同水分的砂床和土床进行了试验研究。
Watermelon with hi-temperature, dry and more light and other characteristics. According to previous studies, watermelon seeds germination minimum temperature of 18 ~ 20 ℃, the optimum temperature of 25 ~ 30 ℃. The root is aerobic, poorly ventilated soil, poor growth, rain and more roots hurt. At present, China’s watermelon production and seed testing work, people often find watermelon seeds germination, once the water is high, then little germination or germination difficulties, which affect the watermelon are sown seedlings and seed germination rate accuracy. In order to investigate the water characteristics of watermelon seed germination, we conducted a pilot study in June 1986 using sand and soil beds of different moisture.
