What should you pay attention to during the flowering and fruiting period of Red Globe grapes? How exactly should you do it?
You can refer to the following methods:
Through flower and fruit management, control the size of the grape cluster. By removing secondary clusters and pinching off the tips of the clusters, save nutrients, reduce the workload of berry thinning, increase the fruit-setting rate, enlarge the berries, and improve fruit quality. Through cluster shaping, you can adjust the grape cluster according to your own requirements, shaping it into clusters of different forms to increase its commercial value.
1. Thinning the inflorescences
After the inflorescences open, promptly thin out the excessive or overly weak inflorescences according to the load capacity.
2. Removing secondary clusters, pinching off cluster tips
When the inflorescences have opened but have not yet flowered, cut off the secondary clusters that affect the cluster shape; to make the cluster compact, pinch off 1/3-1/5 of the cluster tip.
3. Berry thinning
Timing: after physiological fruit drop.
Principle: remove berries that are irregularly shaped, too densely packed, damaged, or squeezed, ensuring the cluster is compact and the berries are uniform.
4. Bagging and bag removal
Carry out after berry thinning. Before bagging, you can first spray the clusters once with a 8000-fold dilution of Fuxing, and bag after the solution dries. For the bags, you can use newspaper or slightly better-quality paper, or you can buy commercial paper bags specially made for grapes. To reduce the occurrence of sunburn, it is best to do this on a cloudy day or in the afternoon when the light is weak and the temperature is not high. Remove the bags 20 days before ripening, or once a small number of berries in the bag have turned red; first open the bottom of the bag into an umbrella shape, then completely remove it after 3-5 days.
