据《Hortscience》(2012年10月)的一篇研究报道,来自美国加利福尼亚州州立理工大学的Michael J.Costello1等人研究了调亏灌溉(RDI)对葡萄枝/果比、水分利用效率、葡萄酒品质和产量的影响。结果表明,调亏灌溉(RDI)提高了葡萄枝/果比、水分利用效率和葡萄酒品质,但降低了产量。本项研究中,研究人员评价了RDI对葡萄产量、浆果大小、果实可溶性固形物含量和酒色的影响。试验在加利福尼亚州圣华金河谷和帕索罗布斯地区的以解百纳红为主栽品种的商业葡萄园里进行。水
According to a study by Hortscience (October 2012), Michael J. Costello1 et al from State Polytechnic University in California studied the effects of RDI on the shoot / fruit ratio, water use efficiency, Quality and yield impact. The results showed that regulated deficit irrigation (RDI) increased the shoot / fruit ratio, water use efficiency and wine quality but reduced the yield. In this study, researchers evaluated the effect of RDI on grape yield, berry size, soluble solids content, and wine color. The experiments were conducted in commercial vineyards dominated by Cabernet Sauvignon in the San Joaquin Valley and Paso Robles areas of California. water
