免整枝栽培方式对西瓜产量和品质的影响

Effect of no-prune on watermelon quality and yield

以4份西瓜品种为材料,研究了免整枝栽培对西瓜产量和品质的影响。结果表明,在免整枝和3蔓整枝2种栽培方式下,‘特大新抗9号’‘郑抗巨丰’‘绿冠’的果实商品率、裂果率、667 m^2产量、可溶性固形物含量和果皮厚度均无显著差异,免整枝栽培方式下单瓜质量显著低于3蔓整枝栽培方式下的;其中,‘特大新抗9号’在2种栽培方式下的667 m^2产量差别最小,分别为5 193.08、5 129.23 kg,‘郑抗巨丰’的中心可溶性固形物含量差异最小,分别为10.70%、10.90%。‘大果黑美人’在免整枝栽培方式下的果实商品率为85.5%,显著低于3蔓整枝栽培方式,其他性状在2种整枝方式下无显著差异。综上所述,‘特大新抗9号’‘郑抗巨丰’和‘绿冠’适合免整枝栽培方式,可以在河南及相似栽培区域推广使用露地免整枝简约化栽培技术。

In order to study the effect of no-prune on watermelon quality and yield, four watermelon varieties were used as materials. The results showed that the marketable rate, cracking rate, 667 m2 yield, soluble solid content and pericarp thickness of ＇Tedaxinkang No. 9＇, ＇Zhengkangjiifeng＇ and ＇Ltiguan＇ were found no significant difference under the two training methods with no-prune and 3 vines prune. But the single fruit weight with no-prune was significantly lower than that with 3 vines prune. The 667 m2 yield of ＇Tedaxinkang No. 9＇ was discovered the smallest difference under two training methods, which were 5 193.08 and 5 129.23 kg respectively. The soluble solid content of ＇Zhengkangjiifeng＇ exhibited the smallest difference under two training methods, which were 10.70% and 10.90% respectively. The marketable rate of ＇ Daguoheimeiren ＇ was 85.5% with no-prune which was significantly lower than that with 3 vines prune, and the other characters showed no significant difference. In conclusion, ＇Tedaxinkang No. 9＇, ＇ZhengkangjOfeng＇ and ＇Luguan＇ were suitable for promoting no-prune technique in the future.
