为科学调节植株营养叶面,提高光合效率,平衡植株体内营养,探讨华南地区大棚西瓜嫁接栽培密度、整枝方式、坐果节位技术等高产优质关键技术,有针对性地设计3种种植密度,配合3个不同坐果节位,2种不同整枝方式,通过栽培比较,研究分析在同等栽培条件下,不同种植密度、坐果节位、整枝方式对大棚西瓜嫁接栽培产量及品质形成的影响。结果表明,最佳的处理为:667 m2密度1 200~1 300株,单蔓整枝留1果,坐果节位在第21~24节间,单果质量可达2.3 kg,果形端正均匀,果实商品率达96%以上,667 m2产量最高达2 870.4 kg。
In order to adjust the nutrition foliage of the plant, improve the photosynthetic efficiency and balance the in vivo nutrition of the plant, the key technologies of high yield and quality, such as the planting density, the pruning method and the fruit setting node technique, were discussed in this paper. Three planting densities, The results showed that the effects of different planting densities, setting nodes and pruning methods on the yield and quality of grafted watermelon grafted under the same cultivation conditions were studied. The results showed that the best treatment was as follows: 667 m2 density of 1 200 ~ 1 300 plants, single vine pruning leave 1 fruit, sitting fruit section in 21 to 24 internodes, single fruit quality up to 2.3 kg, fruit shape is uniform, fruit Product rate of 96% or more, 667 m2 production up to 2 870.4 kg.
