How to Prune 'Golden Finger' Grapes
This article provides a core guide on how to prune 'Golden Finger' grapes and detailed pruning methods related to the cultivation experience of flowering plants. Let's take a look together!
'Golden Finger' grapes are a hybrid of European and American varieties, standing out uniquely in the vast family of grapes. The skin of 'Golden Finger' grapes is of medium thickness, with strong resilience, no cracking, and firm flesh, making them suitable for storage. The grapes have a sweet and refreshing taste, with a strong冰糖 (rock sugar) flavor and a milky taste. They are rich in glucose, which can prevent hypoglycemia and coronary heart disease. 'Golden Finger' grapes contain flavonoids, which have good anti-aging effects and are widely loved by many.
'Golden Finger' Grape Pruning Techniques:
1. Summer Pruning
Summer pruning is done in two steps. The first step is immediate pruning after germination, when the new shoots reach a length of about 15 centimeters. After fixing the shoots, they should be promptly tied up, ending at the flowering stage. After flowering, the main shoot is pinched back for the first time, and all side shoots are left with 1-2 leaves. When the rainy season arrives, only the top side shoot is left, and the rest are removed.
2. Winter Pruning
In winter, the basal buds of 'Golden Finger' grapes are poorly differentiated, while the buds in the middle and upper parts are of better quality. The pruning process mainly focuses on medium and long shoots. For older trees, the base of the main vine should be left with renewal branches to prevent the fruiting part from moving outward. Generally, about 6,000 buds are left per mu, with 3,000 shoots fixed.
3. Flower and Fruit Management
Usually, each fruiting branch of 'Golden Finger' grapes carries 1.5 inflorescences. When the new shoots reach about 15 centimeters in length, combine with shoot fixing to remove excess inflorescences, maintaining a spacing of 12-15 centimeters between new shoots. The ratio of fruiting branches to vegetative branches is 3:1.
4. Thinning Fruit
High-yield orchards can adjust the inflorescence before flowering to make the fruit clusters compact and full. Two weeks after flowering, thinning of the fruit can be carried out, removing small, misshapen, and diseased fruits to better meet the requirements of commercial fruit, which is beneficial for packaging and sales.
5. Bagging Fruit
When the fruit is stable, the fruit clusters can be treated with 50% Baobai 3000x + 50% Dimethazole 3000x + 20% Benzoylpropylthiazole 3000x to ensure the safety of the fruit before bagging. Bagging should be done after the pesticide solution has dried completely. Avoid bagging during high-temperature sunny weather.
6. Fertilization and Water Management
When the seedlings reach about 50 centimeters in length, top dressing is carried out, mainly using urea to promote seedling growth. Apply 10 kilograms of urea per mu, dig shallow trenches 40 centimeters away from the main stem, and water after application. From July, phosphorus and potassium fertilizers are mainly used to promote the maturation of branches. Apply 20 kilograms of monopotassium phosphate per mu. From the second half of September, apply base fertilizer, with 3 cubic meters of decomposed chicken manure and 50 kilograms of compound fertilizer per mu.
