北京地区中果型西瓜吊架栽培初探

Trellis Cultivation of Medium Size Watermelon in Beijing

为了提高瓜农经济效益,采用中果型西瓜密植吊蔓栽培技术,通过667 m2650株、850株、1 050株3种栽培密度设计,对西瓜长势、品质及其经济效益进行了初步研究。结果表明:增加西瓜密度,采用吊蔓栽培管理,对西瓜长势、品质无显著影响,从单瓜质量看,667 m2定植650株平均单瓜质量最高为7.09 kg,667 m2定植850株平均单瓜质量为6.45 kg,667 m2定植1 050株平均单瓜质量达到6.05 kg,适合市场需求。从经济效益上分析,667 m2定植850株的处理2比定植650株的处理1经济效益提高20.26%。667 m2定植1 050株的处理3比定植650株的处理1经济效益提高39.34%,经济效益最高,适合中果型西瓜栽培农户应用。

We evaluated three plant densities,650 plants per 667 m2,850 plants per 667 m2 and 1 050 plants per 667 m2,in trellis production of medium size watermelon to improve the income of watermelon growers in Beijing area. We evaluated plant growth,fruit quality and economic return of 3 treatments. No effects of plant density on plant vigor and fruit quality-were observed in the trial. However,the fruit size was reduced with increase of plant density,7.09,6.54 and 6.05 kg per fruit for densities of 650 plants per 667 m2,850 plants per 667 m2 and 1 050 plants per 667 m2,respectively. All fruit sizes are ac-ceptable for Beijing market. Compared to the low density treatment,the economic benefits of 850 plants per 667 m2 and 1 050 plants per 667 m2 were improved 20.26%and 39.34%.
