摘　　要：以番茄品种‘阪砧1号’和砧木‘齐达利’为试材,采用劈接双断根和贴接双断根嫁接的方法,研究了不同嫁接方式的双断根处理对番茄植株生长以及果实产量品质的影响,以期为番茄栽培生产提供参考依据。结果表明:不同嫁接方式的双断根处理均显著促进了植株生长,提高了番茄产量、可溶性固形物、可溶性蛋白质以及糖含量,但对可滴定酸含量影响较小;劈接双断根处理降低了果实贮藏期的失重率,而贴接双断根提高了果实失重率。双断根嫁接处理可提高番茄产量和品质,而劈接双断根较贴接双断根处理的番茄储藏时间更长。综上所述,双断根嫁接均能提高番茄的生长和产量,改善果实品质。Tomato varieties of ‘Banzhen No.1’ and rootstock ‘Qidali’ were used as experimental materials.With the method of cleft double root-cutting graft and close-joining double root-cutting graft, the effects of double root cutting treatments with different grafting methods on tomato plant growth, fruit yield and quality were expected to provide a refence for tomato cultivation and production.The results showed that double root-cutting grafting treatments of different grafting methods significantly promoted plant growth, increased tomato yield, soluble solid, soluble protein and sugar content, but had little effect on titratable acid content.The weight loss rate of fruit during storage was decreased by cleft root-cutting, but increased by close-joining graft.In this experiment, the yield and quality of tomato could be improved by double root-cutting grafting, and the storage time of tomato with cleft double root-cutting graft was longer than that with close-joining double root-cutting graft.In conclusion, double root-cutting grafting could improve the growth, yield and fruit quality of tomato.
