双叶幕层棚架栽培对“SN2016”猕猴桃性状的影响

Effect of double-canopy trellis cultivation on the characters of SN2016 kiwifruit

以“SN2016”猕猴桃为试材,比较双叶幕层棚架(在平顶棚架上建斜面牵引层)和平顶棚架猕猴桃主要性状表现。结果发现,双叶幕层棚架猕猴桃主要生长特性及经济性状如萌芽率、结果枝率、平均单果质量、可溶性固形物及产量均高于平顶棚架;营养枝二次梢和三次梢萌发率均低于平顶棚架。双叶幕层棚架作为猕猴桃优选栽培架式,在生产中有推广应用价值。

Taking SN2016 kiwifruit as the test material,the main characteristic performances of kiwifruit with double-canopy trellis(building an inclined traction layer on the flat-top trellis)and the flat-top trellis were compared.The results showed that the main growth characteristics and economic traits of kiwifruit with the double-canopy trellis,such as the germination rate,fruiting branch rate,the average single fruit weight,soluble solids and yield,were all higher than those of the flat-top trellis,while the germination rates of secondary and tertiary shoots of vegetative branches of the double-canopy trellis were lower than that of flat-top trellis.The double-canopy trellis is an optimized cultivation trellis for kiwifruit and has the value of popularization and application in production.
