摘　　要：【目的】研究极端干旱区‘厂’形栽培条件下,结果高度对酿酒葡萄果穗微域环境、果实发育及酒质的影响,为极端干旱区陈酿型酿酒葡萄原料品质提升及‘厂’形标准化栽培适宜结果高度的选择提供参考。【方法】以吐鲁番地区‘厂’形栽培的6 a生赤霞珠葡萄为试材,设置不同结果高度(40、60、80、100 cm),分析不同结果高度葡萄生长期果穗微域环境、果实发育、成熟期果实品质及葡萄酒品质差异。【结果】结果高度不同,葡萄生长发育阶段果穗微域温、湿度、光合有效辐射存在差异。40 cm平均温度较80、100 cm分别降低0.84℃(2.77%)和0.73℃(2.42%);40 cm超过35℃温差总和、≥35℃高温时长较80、100 cm分别降低7.58%、13.39%和10.54%、13.87%;40、60 cm相比80、100 cm果穗微域平均湿度分别提高8.86%、4.90%和15.40%、11.21%;40 cm中午至夜间温度处于最低水平,湿度全天均处于较高水平;40 cm较60、80、100 cm平均光合有效辐射降低20.81%、21.85%和37.95%,全天光合有效辐射值一直处于最低水平。果实发育后期结果高度越高果粒质量和果粒体积降低越显著,果实失水萎蔫程度越高,造成糖、酸及部分酚类物质浓缩。采收期果穗质量随结果高度增大而减小,100、80 cm的果穗质量较40 cm分别减小45.38%和20.75%;100、80 cm果粒质量较40 cm分别减小16.67%、10.78%。40 cm的果穗紧密度表现为适中稍偏紧,相比80、100 cm萎蔫率降低91.41%和76.87%,种皮颜色、果皮颜色值亦相对较低;40 cm相比60、80、100 cm还原糖质量浓度降低6.32%、8.76%和13.35%,相比60、80 cm总酸质量浓度提高6.46%,果皮总酚含量较60、80、100 cm增加6.84%、13.02%和8.63%。40 cm的葡萄酒酒精度、花色苷含量低,但酸度高、单宁含量较为丰富。【结论】极端干旱区采用低‘厂’形(40 cm)栽培能够有效改善果穗微域环境,避免高温、低湿、强光造对果实不利影响,有效改善�【Objective】To study the effects of fruit set height on cluster micro-environment,fruit quality and wine quality of wine grape under‘M-VSP’in extreme arid region in the hope of providing a reference for the improvement of raw material quality of aging wine grape and the selection of suitable fruit set height for standardized cultivation of‘M-VSP’cultivation in this kind of environment.【Methods】Different fruit set height(40 cm,60 cm,80 cm and 100 cm)of 6 years old wine Cabernet Sauvignon grapes were taken as experiment materials to analyze the cluster microenvironment,fruit development,fruit quality and wine quality of different fruit set heights.【Results】Cluster microdomain temperature,humidity and PAR were different in different fruit set heights during the growth stage of wine grape,average temperature of 40cm was 0.84℃(2.77%)and 0.73℃(2.42%)lower than 80cm and 100cm respectively,temperature difference sum and heat hours of 40 cm exceed 35℃decreased by 7.58%,13.39%and 10.54%,13.87%respectively compared with 80 cm and 100 cm,average humidity of cluster microdomain of 40 cm and 60 cm were increased by 8.86%,4.90%and 15.40%,11.21%compared with 80 cm and 100 cm.The temperature from noon to night of 40cm was the minimum,but humidity of all day was higher than others,PAR of 40 cm was decreased by 20.81%,21.85%and 37.95%compare with 60 cm,80 cm and 100 cm,and PAR of 40 cm the whole day was the minimum.The higher bearing height,the smaller berry weight and berry volume and the higher degree of wilting at later fruit development,so sugar,acid and some phenols began to concentrate.Cluster weight was decreased along with bearing height increase,cluster weight and berry weight of 100 cm and 80 cm were decreased by 45.38%,20.75%and 16.67%,10.78%compared with 40 cm.Cluster of 40 cm was moderation,wilting percent decreased by 91.41%and 76.87%,seed coat color and skin color value was relatively low.Reducing sugar mass concentration and total phenols of 40 cm was decreased by 6.32%,8.76%,13.35%and 6.84%
