摘要 通过1987年和1988年对春季迟播西瓜的产量,产量结构、果实品质和采摘期的研究表明:春季迟播西瓜以4月15日为最佳播期,4月15—20日为适宜播期。在此播期范围内,对产量影响极大的单株结瓜数相对较多,且7月26日后的采摘量达58.3%以上,果实品质也较佳。供应上海市区的商品西瓜约有80%来源于本市郊区,且集中在7月25日前,而外地晚熟西瓜则于8月中旬前后才进入上海市场。故为了满足市场在7月26日以后对晚西瓜的需要,安排一定面积的春季迟播西瓜,将播期适当推迟至4月15—20日,达到推迟采摘期的目的,是在不影响产量和品质的前提下而延长供应期的有效途径之一。 The studies carried out in 1987 and 1988 on yield, yield components, fruit quality and picking time of spring late-sowing watermelon showed that April 15 was the optimal date for spring late sowing, and the dates from April 15-20, however, were all considered as suitable sowing times. Sown within this period, the number of fruits born on a single plant, which had great influence on the yield, was relatively more great. In addition, the fruit harvesting rate after Jul. 26 attained 58.3% or more of the total yield and the fruit quality was better as well.On the markets of Shanghai urban districts, about 80% watermelons came from Shanghai rural production and whose supply time was concentrated before Jul. 25, while the late-watermelons produced from other regions appeared on Shanghai markets near the middle of Aug. Therefore, properly postponing sowing time to April 15-20 is one of the efficient ways for defering the picking time and extending the watermelons supply period on the market in order to satisfy the market requirements post Jul. 26.
