调亏灌溉对焉耆盆地梅鹿辄葡萄品种果实品质的影响

为了解调亏灌溉（regulated deficit irrigation,RDI）技术对酿酒葡萄生长及果实品质的影响，为酿酒葡萄节水灌溉技术提供理论依据。在大田条件下，以焉耆盆地葡萄欧亚种酿酒品种梅鹿辄（Merlot）为试材，以不同的灌水量进行调亏灌溉，对葡萄生长及果实品质进行比较分析。结果表明：在RDI条件下，中度调亏（16h）灌溉可有效的提升梅鹿辄葡萄的总酚及花色苷物质的含量，分别比对照（CK）提高了13.92%、24.35%，但对百粒重、可溶性固形物、单宁含量的影响并不大。中度（16h）的调亏灌溉既可以节约浇水量，又可以有效的提升梅鹿辄葡萄果实的品质。

Effect of Regulated Deficit Irrigation on Fruit Quality of Merlot Grape Varieties in Yanqi Basin

This paper study on the regulated deficit irrigation(RDI) technic influenced the vitis viniferra growing and quality, providing evidence to water-saving irrigation for vitis viniferra.Under field level, Merlot, a grape Eurasian wine-making cultivar in Yanqi Basin, was used as the test material to conduct a comparative analysis of grape growth and fruit quality by adjusting deficit irrigation with different irrigation volumes.Results : Under the RDI circumstance, Under RDI conditions, moderate deficit regulation (16h) irrigation could effectively increase the total phenol and anthocyanin content of Merlot grape, which were 13.92% and 24.35% higher than CK, respectively, but had little effect on 100-grain weight, soluble solids and tannin content.Moderate deficit-adjusted irrigation can not only save water, but also effectively improve the quality of Merlot grape fruit.
