How to Prune巨峰 Grapes
Regarding the pruning methods for巨峰 grapes in green plant maintenance, here are the detailed explanations by the editor below.
How to Prune巨峰 Grapes
巨峰 grapes are pruned in winter and summer. The pruning mainly involves medium to long shoots, with one shoot retained every 80 centimeters on the main vine. Strong branches should be left with 7-12 buds, medium branches with 4-7 buds, short shoots with 1-3 buds, and weak branches without buds. Excess and weak branches should be thinned before flowering. After harvest, the branches should be cut short to reduce nutrient consumption, promote shoot maturity, and increase the fruit-setting rate the following year.
When to Prune巨峰 Grapes
巨峰 grapes are pruned in winter and summer. Winter pruning is to help them survive the winter better, while summer pruning aids in better growth.
Cutting: Cut a semi-woody long shoot of巨峰 grapes, retain a green leaf at the top, insert it into the soil, and provide it with adequate sunlight and water. It will quickly root and sprout.
Pruning the Branches and Leaves of巨峰 Grapes
When pruning巨峰 grapes, focus on medium to long shoots, with one shoot retained every 80 centimeters on the main vine. Strong branches need to be left with 7-12 buds, medium branches with 4-7 buds, short shoots with 1-3 buds, and weak branches without buds. Excess and weak branches should be thinned before flowering.
Pruning Techniques for巨峰 Grapes
After germination in spring, remove double buds, weak buds, and unnecessary buds as soon as possible, leaving only one strong bud per bud eye. The second thinning should be done 10 days after the first, continuing for 2-3 weeks, selecting the main bud and removing all others.
Moderate pinching before flowering can control vegetative growth and increase fruit-setting rate. Pinching should be done when there are 5-7 leaves above the flower cluster, with fruiting branches left with 4-7 leaves and nutrient branches with 15-20 leaves for pinching. Remove all lateral branches below the fruit cluster and leave 1-2 leaves on those above, repeatedly pinching to ensure adequate nutrients.
Pruning Results for巨峰 Grapes
Two weeks before flowering,同时 perform thinning of inflorescences and pinching of the inflorescence tip. Leave one inflorescence per shoot, with strong branches left with two. Remove 1/3 of the tip of the spike and thin out dense and irregular weak spikes.
Pruning Precautions for巨峰 Grapes
After harvest,巨峰 grapes need to be cut short to reduce nutrient consumption, promote shoot maturity, and increase the fruit-setting rate the following year. Timely remove overly strong, dense, and diseased branches to maintain good ventilation and light penetration.
