摘　　要：【目的】研究不同整枝方式对黑皮冬瓜生长发育及产量的影响,为华南地区黑皮冬瓜优质、高效栽培提供技术支持。【方法】在1.2 m2/株的种植密度下,调查黑皮冬瓜开花期、测定生长势指标和果实性状,探讨单蔓单瓜、双蔓单瓜、双蔓双瓜3种不同整枝方式对黑皮冬瓜开花期、叶片大小、单瓜重及产量的影响。【结果】黑皮冬瓜整枝方式对叶面积大小、茎粗、单瓜重、纵横径大小及果肉厚等植株生长势指标影响大小依次为单蔓单瓜>双蔓单瓜>双蔓双瓜。单蔓单瓜整枝方式的单瓜重最大(14.10 kg),但其单位面积产量最低,仅为128927.25 kg/ha,其次是双蔓单瓜整枝方式,产量为143234.70 kg/ha,双蔓双瓜整枝方式的产量最高,为203567.40 kg/ha。【结论】在相同种植密度下,不同整枝方式对黑皮冬瓜生长发育及产量的影响不同,单蔓单瓜整枝方式的单瓜重最大,双蔓双瓜整枝方式的黑皮冬瓜产量最高,生产上可以根据实际选择合适的整枝方式。[Objective]Effects of different pruning methods on growth and yield of black wax gourd were studied to pro- vide technical support for high-quality and high-efficient cultivation of black wax gourd. [ Method ] Under the same planting density of 1.2 ms per plant, flowering indicators, growth vigor and fruit traits were determined to explore the effects of three different pruning methods （one wine with one gourd, two wines with one guard, two wines with two gourds） on flowering, leaf size, average fruit weight and yield. [Result]The results indicated that the influencing order for total leaf size, petiole size, average fruit weight, longitudinal and transverse diameter, and flesh thickness was one wine with one gourd 〉 two wines with one gourd 〉 two wines with two gourds. In the mode of one wine with one gourd, average fruit weight was the highest （14.10 kg）, while the yield per ha was the lowest yield of 128927.25 kg/ha. In the mode of two wines with one gourd, the yield was 143234.70 kg/ha. The yield was the highest in the manner of two wines with two gourds （203567.40 kg/ha）. [Con- clusion]Under the same planting density, different pruning methods had varied effects on growth and yield of black wax gourd. The pruning methods of one wine with one gourd had the highest average fruit weight, and the pruning methods of two wines with two gourds had the highest yield. Farmers can choose the appropriate pruning methods according to the practical situation.
