摘 要:为了维持多年生盆栽葡萄的持续生长能力和观赏性,研究了不同切根处理对苗木更新复壮的影响。结果表明:不同切根方法和切根程度组合处理对更新复壮的影响差异较大,相同切根程度下,纵切效果优于横切。不同切根处理中,纵切50%根系处理的叶面积、叶厚、叶绿素含量、新梢长、新梢粗、节间距、单粒重、穗重和可溶性固形物含量最高,分别为170.07 cm2、3.57 mm、3.18 mg/g、83.16 cm、10.93 mm、13.45 cm、13.71 g、617.75 g和13.82%,较对照(CK)分别提高了19.75%、111.24%、67.37%、35.93%、48.91%、56.76%、45.54%、45.78%和36.43%,差异均达到极显著水平(P<0.01),且叶色浓绿、冬芽饱满、果色深红,建议应用此处理来更新复壮盆栽葡萄。

Abstract:In order to keep persistent growth capacity and appreciation of perennial potted grape, the effect of different cutting root treatment on renewal of potted grape was studied. The result showed that the effect of different cutting method and grade combination on renewal was distinct, the effect of vertical cutting was well than horizontal cutting under same grade, the leaf area, leaf thickness, chlorophyll content, shoot length, shoot thickness, node spacing, single fruit weight, spike weight and soluble solids content of vertical cutting 50% root were highest in all treatments, which were 170.07 cm2, 3.57 mm, 3.18 mg/g, 83.16 cm, 10.93 mm, 13.45 cm, 13.71 g, 617.75 g and 13.82%, and increased 19.75%, 111.24%, 67.37%, 35.93%, 48.91%, 56.76%, 45.54%, 45.78% and 36.43% . Comparing to CK separately, the difference reached to extremely significant (P<0.01), and the leaf color was dark green, the winter bud was plump, the fruit color was deep red, the treatment should be used to renew potted grape.

盆栽葡萄可根据人们的艺术构思和各自的爱好,塑造出各种栽培艺术形式,是庭院和室内绿化、美化的重要形式之一。盆栽葡萄种植在有限的容器内,容器盛装的土壤或基质数量有限,生长多年后,盆内根系纵横交错,土壤肥力下降、质地僵硬,葡萄苗木表现出黄化、生长势减弱和结果能力下降等不良现象,影响了盆裁葡萄的观赏性。在葡萄栽培过程中,人们对枝梢修剪技术的研究较多,在生产中也应用较多,而对根系修剪技术的研究较少[1-3]。本试验在多年生盆栽葡萄换盆时,对根系进行切根处理,切根后研究了不同处理对盆土肥力、叶片生长、枝条生长和结果能力的影响,以期为多年生盆栽葡萄苗木更新复壮提供技术参考。
