摘要:

本研究以西瓜品种京嘉301为主要研究对象,在浙江省杭州市余杭区的钢架塑料大棚内开展区域试验,系统对比了其与主流品种美都、早佳8424在植株长势、果实发育期、坐果率、抗逆性、产量构成及果实品质等方面的表现。试验采用随机区组设计,于2025年2月至6月进行,统一水肥管理及双蔓整枝方式。结果表明,京嘉301的产量显著(p<0.05)高于对照品种,667 m2产量达5 433.3 kg,单果重达6.78 kg;在果实品质方面,京嘉301的中心糖度(12.93%)与边缘糖度(9.57%)均较高,糖分分布均匀,口感均衡;京嘉301的果皮厚度为1.17 cm,介于2个对照品种之间,兼顾了储运性与可食率。此外,京嘉301表现出适宜的成熟期、较高的坐果率和较强的抗逆能力。综上所述,京嘉301实现了高产、优质与高抗逆性的协同效应,适宜于在相似生态区域进行推广。本研究借助多指标系统评价,验证了京嘉301在现代化西瓜产业中的应用潜力,为西瓜品种选育和栽培优化提供了理论支撑。

Abstract:

This study primarily focused on the watermelon variety Jingjia 301,and conducted regional trials in steel-framed plastic greenhouses in Yuhang District,Hangzhou City, Zhejiang Province. A systematic comparison was made between Jingjia 301 and mainstream varieties Meidu and Zaojia 8424 in terms of plant growth,fruit development period,fruit setting rate,stress resistance,yield composition,and fruit quality. The trial adopted a randomized block design and was conducted from February to June 2025,with unified water and fertilizer management and double-cord pruning. The results demonstrated that Jingjia 301 achieved significantly (p<0.05) higher yields than the control varieties,reaching 5 433.3 kg per 667 m2 with a single fruit weight of 6.78 kg. In terms of fruit quality,Jingjia 301 exhibited higher central sugar content(12.93%)and edge sugar content(9.57%),with uniform sugar distribution and balanced flavor. The peel thickness of Jingjia 301 was 1.17 cm,intermediate between the two control varieties,balancing storage and transportability with edibility. Additionally,Jingjia 301 demonstrated suitable maturity period,high fruit setting rate,and strong stress resistance. In summary,Jingjia 301 achieved a synergistic effect of high yield,superior quality,and strong stress resistance,making it suitable for promotion in similar ecological regions. This study employed a multi-index system evaluation to validate the application potential of Jingjia 301 in modern watermelon production,providing theoretical support for variety selection and cultivation optimization.

Key words: watermelon, Jingjia 301, yield, stress resistance, fruit quality
