Influences of different irrigation methods and pruning patterns on the plant growth and fruit characters of watermelon in protected production

以有籽西瓜‘红和平’为试验材料,探讨不同灌溉和整枝方式对设施西瓜植株生长及果实性状的影响。试验结果表明,设施栽培条件下,不同灌溉和整枝方式对西瓜主蔓长度、主茎粗度有明显影响,对主蔓叶片数、叶片光合速率、果皮厚度及可溶性固形物含量影响较小。滴灌+双蔓整枝较其他处理叶片密度适中,节水省工,西瓜平均单果质量和产量最高,是设施西瓜首选的栽培管理方式之一。

Watermelon variety ＇Hongheping＇ was used to discuss the influence of different irrigation methods and pruning patterns on the plant growth and fruit characters of watermelon in protected production. The results showed that the plant height and stem diameter were significantly affectedby different irrigation methods and pruning patterns,and leaf number, photosynthesis rate,thickness and soluble solids were little affected. The plants treated by drip irrigation and double cross training had more reasonable leaf density,d the highest average fruit weight and yield,this treatment was considered as one of the best cultivation management pattern.
