摘要
【目的】比较研究2种不同架式对鲜食葡萄多年生大树在栽培性状、果实品质、病害发生情况等的影响,为华北冲积平原埋土区推广适宜的葡萄栽培架式提供参考。【方法】以鲜食葡萄‘瑞都脆霞’‘瑞都无核怡’和‘瑞都香玉’为试材,分别采用T型架和V型架栽培,系统分析2种架式对葡萄物候期、生长结果习性、光合作用、树体结构、果实基本理化指标,多酚化合物含量和栽培用工等方面的影响。【结果】2种架式的物候期和结果习性差异不显著。T型架葡萄副梢管理次数、摘心次数、结果枝绑缚次数和冬季修剪工时均小于V型架,二者冬季下架埋土和春季出土上架所用工时无显著差异。‘瑞都脆霞’T型架在2017年的净光合速率小于V型架,‘瑞都无核怡’T型架在2016年的净光合速率小于V型架,其他情况均表现为T型架的光合性能更强。2017年3个品种在2种架式下的新梢粗度无显著差异。新梢粗度标准差的结果表明,当葡萄树体的树势由强旺调控至中庸水平后,3个品种在T型架的新梢粗度标准差分别为2.3、2.6和2.3,低于V型架的2.7、2.75和3.0,表现出更强的新梢一致性。3个品种在叶幕高度和叶幕长度的表现有所差异,但是V型架的叶幕厚度和叶幕体积均大于T型架,其中‘瑞都脆霞’和‘瑞都香玉’达到显著水平;‘瑞都脆霞’和‘瑞都香玉’在V型架下的叶面积指数高于T型,‘瑞都无核怡’结果相反;2种架式下的叶片叶绿素含量并无显著差异。V型架的叶片霜霉病发病率和病情指数均显著高于T型,白粉病差异不显著。在产量调控至同一水平时,2种架式的穗重、单粒重、纵横径和可溶性固形物之间无显著差异,但是2016年和2017年T型架下葡萄果实的固酸比显著优于V型架。‘瑞都脆霞’和‘瑞都无核怡’在T型架下的总花色苷含量高于V型,其中‘瑞都无核怡’达到显著水平
【Objective】The effects of two different trellis systems on viticultural characteristics,fruit quality and disease incidence of three table grape cultivars were studied deeply to provide theoretical basis for the selection of appropriate trellis system for Northern China alluvial plain.【Method】Vitis vinifera L.were used as plant materials,including Ruiducuixia,Ruiduwuheyi and Ruiduhongyu,which were planted with'T'shaped and'V'shaped trellis systems,respectively.Phenological stages,fruiting habits,photosynthetic characteristics,vine structure,labor intensity,fruit quality indexes including cluster weight,berry weight,berry width,berry length,total soluble solids(TSS),titratable acidity(TA),total anthocyanins,flavonoid and proanthocyanidin of three cultivars in both trellis systems were measured.【Result】There was no significant difference in phenological stages or fruiting habits.In most cases,percentage of germination showed higher value with T-trellis,while other fruiting habits showed no significant differences.T-trellis showed considerable advantages in management operations of the vineyard,in terms of the lateral shoot management,topping of primary shoot,fruit branch binding and winter pruning.Both Soil-bury and untying hours in the fall and out-of-soil and tying hours in the spring showed no statistically difference between the two trellis systems.Ruiducuixia showed higher net photosynthetic rate(Pn)with V-trellis in 2017,Ruiduwuheyi showed higher Pn with V-trellis in 2016,in other cases,T-trellis showed significantly higher Pn.Ruiduwuheyi showed higher stomatal conductance with T-trellis for the three years but the other two cultivars showed inconsistent results.Ruiducuixia had a higher transpiration rate with V-trellis;Ruiduxiangyu had the same trend in 2016.In most cases,there was no difference in intercellular CO2 concentration between the two trellis systems.The shoot width of three cultivars showed trivial difference between the two trellis systems in 2017.However,after the vigor of the vine
