Does the grapevines need pruning after fruiting?
This article introduces whether grapevines need pruning after fruiting and related topics about flower cultivation and pruning methods. Next, the editor will introduce to the netizens.
Pruning grapevines after fruiting is a necessary step, which helps to improve the quality and yield of grapes. The following are the relevant knowledge and maintenance pruning methods for grapevines after fruiting.
I. Why do grapevines need pruning after fruiting? 1. Promote nutrient concentration: Removing excessive branches allows nutrients to be more concentrated in the fruiting branches, thus improving the quality and yield of grapes.2. Improve ventilation and lighting: Pruning can increase the ventilation and lighting of the grape trellises, which is beneficial for the prevention and control of diseases and pests and the growth of grapes.3. Control tree growth: Proper pruning can control the growth momentum of the grapevine, prevent excessive vigor, and avoid excessive nutrient consumption.4. Promote renewal: Pruning can promote the growth of the grapevine and encourage the production of new branches, which is beneficial for tree renewal.
II. How to prune grapevines after fruiting?1. Pruning time: Pruning of grapevines after fruiting is generally carried out after fruit harvesting when the branches have matured and are easy to identify and operate.2. Pruning methods: - Thinning: For dense, severely diseased, or poorly growing branches, thinning should be performed. Remove weak, crossing, and inward-growing branches and retain strong, outward-growing branches. - Shortening: For fruiting branches, shorten them according to the length and growth momentum of the branches. Generally, retain a length of 40-50 centimeters and cut off the top tender branches. For overly long branches, shorten them appropriately to promote their differentiation into fruiting branches. - Pinching: For excessively vigorous branches, pinch off the top 5-6 leaves to slow down their growth and promote fruiting. - Defoliating: During the fruiting period, timely remove some old and diseased leaves to facilitate ventilation and lighting, reducing the occurrence of diseases and pests.3. Precautions for pruning:- Keep the pruning shears sharp to avoid damaging the branches. - Apply pruning paste promptly after pruning to prevent poor healing of the cuts. - Follow the principles of "thinning, shortening, pinching, and cutting" to maintain a reasonable tree structure. - After pruning, pay attention to fertilization and water management to ensure the nutrients needed for grape growth.
III. Grape maintenance pruning techniques:1. Choose the right grape variety: Select suitable grape varieties based on local climate, soil conditions, etc.2. Establish a reasonable grape trellis: Choose an appropriate grape trellis, such as a V-trellis or flat-top trellis, based on the growth habits of the grape variety.3. Keep the soil moist: During the growth of grapes, keep the soil moist and avoid drought and waterlogging.4. Control diseases and pests: Prevent and treat diseases and pests in a timely manner to ensure healthy growth of grapes.5. Reasonable fertilization: According to the growth needs of grapes, fertilize appropriately to promote their growth.By using the above methods, the quality and yield of grapes after fruiting can be effectively improved, bringing joy of harvest to grape growers. During pruning, it is necessary to follow scientific pruning principles to ensure the smooth growth of grapes.
