Embodiment 1

[0018] The Cabernet Sauvignon grape variety is used to carry out tree-dried grape production, and the specific operation process is as follows:

[0019] From germination to the early stage of new shoot growth, the method of wiping buds and fixing shoots is used to keep 13-14 new shoots per meter of shelf surface, and keep one fruit ear for each fruiting new shoot, and leave two fruit ears on the top. Determine the number of ears in the young fruit expansion stage; soil fertilization is carried out according to the ratio of N: P: K: Ca 1: 0.5: 1.2: 0.8, and before germination, 8.5Kg of urea, 10Kg of calcium magnesium phosphate fertilizer, and 2.4Kg of potassium sulfate are applied to each acre of germination. Apply 1.5Kg of urea, 10Kg of calcium magnesium phosphate fertilizer, and 5.6Kg of potassium sulfate during the expansion stage of young fruit. The fertilization method is furrow application, and the fertilization depth is 40-50cm; the leaves are sprayed multiple times and d...

Embodiment 2

[0024] The Cabernet Sauvignon grape variety is used to carry out tree-dried grape production, and the specific operation process is as follows:

[0025] From germination to the early growth stage of new shoots, 14-15 new shoots are kept on the shelf surface of each meter long by wiping buds and fixing shoots, and one fruit ear is reserved for each fruiting new shoot, and two fruit ears are removed and left. Determine the number of ears in the young fruit expansion stage; soil fertilization is carried out according to the ratio of N:P:K:Ca 1:0.5:1.2:0.8, and 7Kg of urea, 11Kg of calcium magnesium phosphate fertilizer, and 2.5Kg of potassium sulfate are applied to each acre before germination. Apply 2Kg of urea, 11Kg of calcium magnesium phosphate fertilizer, and 5.5Kg of potassium sulfate during the fruit expansion period. The fertilization method is furrow application, and the fertilization depth is 40-50cm; the leaves are sprayed multiple times in 4 times: the first spray is c...

Abstract

The invention provides a tree-mounted desiccated grape cultivation method. The method belongs to the technical field of delayed harvesting of wine grapes. The method mainly comprises the technical operating links of prescription fertilization, load control, berry protection and the like. In the method, wine grape varieties are used as objects; the element ratios of various fertilizers, damage by diseases and insects and fruit cluster bagging are controlled by controlling the number of young sprouts and the amount of fruit clusters of each young sprout on unit treillage surface, soil fertilization application and foliage application, so that the berry is protected; the grape harvesting is delayed; and the grapes can still be kept for over 100 days on trees after being matured and even reach an icing state, so that the grape berry is naturally desiccated and dehydrated and has sugar content of over 300g / L. The desiccated grapes produced by adopting the method not only have high sugar content, but also have various concentrated flavor compound ingredients. High-grade sweet wine or ice wine with more full-bodied and fragrant flavor and more rich nutritions can be produced by using thedesiccated grapes as raw materials.

Description

technical field [0001] The invention relates to the technical field of viticulture, in particular to a tree-mounted dried grape cultivation method. Background technique [0002] Generally, in some countries and regions, such as Spain, France, Italy, etc., there is a practice of using dried grapes as raw materials to produce wine, but the production methods of dried grapes are all carried out under the premise that the grape ears are separated from the tree. The methods include cutting off the fruit stems and letting the ears hang on the tree to dry, harvesting the grape ears and drying them on the spot, putting them on a layer of straw or a sieve to dry them, and hanging the harvested grapes collectively. Let it dry, put it in the room naturally or dry it with temperature and humidity control. In the special areas of a few countries (Germany, Canada and Austria), due to the special climatic conditions, some specific grape varieties can be properly delayed until freezing, an...
