中果型西瓜不同授粉方式的效果

为了降低瓜农的劳动强度,研究西瓜不同授粉方式,对地爬中果型西瓜京欣3号蜜蜂授粉、激素授粉和人工对花授粉方式的效果进行比较.结果表明：3种授粉方式的植株长势在整个生育期无明显影响,植株长势良好.蜜蜂授粉的植株坐果率最高为100％;人工授粉方式的植株单瓜质量最高为5.89 kg,但经统计分析在5％水平上无显著差异.在3种不同的授粉方式中,蜜蜂授粉处理西瓜中心可溶性固形物含量最高,达到11.24％;667 m2产量和经济效益也最高,分别为4 231 kg和13 409元,显著高于激素授粉和人工授粉,且蜜蜂授粉西瓜果形周正品质好.综合考虑产量、坐果率和品质等指标,中果型西瓜蜜蜂授粉表现最为优异,蜜蜂授粉绿色环保,大大降低了农户的劳动强度.

Effect of Pollination Methods on Medium Size Watermelon Production

Bee pollination, hand pollination and growth regulator treatment were compared for the production of medium size seeded watermelon＂Jingxin No. 3＂ The results showed that three treatment did not affect the growth of the variety during pro- duction. Fruit set was the highest, reached 100%, with bee pollination. Fruit weight was the highest, reached 5.89 kg, with hand pollination ,but the differences were not significant among treatments. The soluble solids content was highest with bee pollination, reached 11.24%. The yield and revenue per 667 m2 for bee pollination were 4,231 kg and 13,409 yuan ,respec- tively. The bee pollination produced highest yield, best quality and good size uniformity among three treatments. The bee pollination production also had the lowest inputs cost.
