针对辽宁省桓仁县因冬季埋土防寒而造成的威代尔葡萄冷冻与树体分离(离体冻)问题,系统研究了葡萄连体冻(留在树上自然冷冻)的适宜架式和整枝方式、更新修剪方法等栽培技术。结果表明:在冬季防寒区冰葡萄连体冻应采用篱架栽培、双臂水平形整枝,并实施双株或双蔓更新交替结果;双壁篱架产量高于单壁篱架和V形架,连体自然冷冻后667 m2产量可达669.7 kg;连体自然冷冻与离体自然冷冻方式对葡萄汁及原酒中主要成分影响不大,但连体自然冷冻方式更符合国际冰葡萄生产标准。
Aiming at the problems of freezing and de-bodying of Vydair grape in Huanren County, Liaoning Province, which is caused by the cold embedding in winter, the suitable shelving and Pruning methods, such as updating pruning cultivation techniques. The results showed that in the winter cold-freezing area, the split of iced-grape should be used in the field of rape cultivation, the horizontal arm of the arm should be pruned, and the double-arm or double-bracken should be replaced. The yield of double-wall raisers is higher than that of single-wall racks and V- , The natural frozen 667 m2 output of up to 669.7 kg; Siamese natural freezing and isolated natural freezing methods on the main components of grape juice and the original wine has little effect, but the Siamese natural freezing more in line with international standards of ice grape production.
