When to Prune Grapes
This article introduces the related experience of pruning grapes, let's learn about it together.
When to Prune Grapes
Grapes are a fruit cultivated in many regions. To ensure the yield and quality of grapes, proper pruning management is essential. So, when should grapes be pruned? What are the pruning methods? Let's find out.
When to Prune Grapes?
Grapes can be pruned all year round, with different effects depending on the season. For example, pruning in mid-spring is a method of wiping the flower buds in mid-spring, which can eliminate multiple buds, thin buds, and bad buds, thereby saving nutrients. Summer pruning involves removing the center of the fruiting and nutrient branches, slightly treating the secondary branches, pinching the scrolls in sequence, shaping the fruit clusters, and thinning the clusters along the spikes.
The task of autumn pruning is to remove closed branches, weak branches, and branches with low lignification, adjust the number of branches, see the brightness of the branches, improve lighting conditions, and make the surface of the shelves more transparent. In addition, winter pruning is also an effective method to determine the yield for the coming year. Below is a detailed introduction to winter pruning of grapes.
Operational Methods for Pruning Grapes
1. Standards
Primarily depend on the variety, age of the tree, tree vigor, trellis style, bud eyes, maturity of the branches, and the growth status of adjacent trees. Determine the pruning amount and standards based on the number of fruiting branches, number of bud eyes, and expected yield for each variety.
2. Thinning Branches
Refers to thinning branches that are diseased, weak, or dead, main lateral branches that are too dense and wilted, and dead stakes and buds that are not useful.
3. Cutting
Based on the standard of pruning amount, determine the appropriate amount of pruning for the mother branches, and prune the one-year-old branches according to specific conditions; choose the cutting length based on factors such as the variety, trellis type, summer branch management, and cultivation environment.
Precautions for Pruning Grapes
1. Cut surfaces should be flat, smooth, and without stubble. The thickness of the cut surface should be 1-2 cm to avoid drying out the winter buds.
2. Apply a wound protectant or white latex to the wounds to protect them.
3. To avoid frost damage, short stakes should be removed next year.
4. Avoid mouth-to-mouth injuries that could damage the tree body, injure the flowing sap, and cause the tree to become weak.
Pruning is an important measure in grape cultivation. The purpose of pruning is to regulate the movement of water and nutrients, improve the physiological activity of fruit trees, and enhance ventilation and light conditions, strengthen assimilation, and reduce the occurrence of diseases.
The above is a specific introduction to when to prune grapes, hoping to bring some flower knowledge to flower enthusiasts.
