Grape Flower and Fruit Management Techniques
The editor introduces you to the green plant maintenance experience of grape flower and fruit management techniques, let's take a look together!
Grape Flower and Fruit Management Techniques
Currently, the grape market in this country is very large. Grapes can not only be consumed as fresh fruit but can also be processed into raisins, wine, and other foods. They are very popular in the market. When growing grapes, grape management is very important, especially during the flowering and fruiting period. So the editor brings you the management techniques for grape flowering and fruiting period today. Let's see!
Reasonable Loading
Grape vines have a load range. If the amount of flowers and fruits on grapes exceeds the load range, it will not only fail to increase yield but also lead to a phenomenon of massive flower and fruit drop, resulting in reduced yield. The yield per mu during the flowering and fruiting period should not exceed 2000 kilograms. The loading per square meter is about 3 kilograms of fruit. According to the variety, if the bunch is small, the weight of each bunch should be controlled at around 300 grams. The number of fruit bunches on each fruiting branch should not exceed 2, and excess flower bunches should be removed in a timely manner to ensure that the amount of flowers and fruits is within the load range of the grape.
Foliar Fertilization
Applying borax and other foliar fertilizers appropriately during the grape flowering period can effectively improve the grape setting rate. Foliar fertilization should not be carried out on sunny days but should be done on cloudy days or in the early morning and evening. This can prevent rapid evaporation due to high temperatures after spraying. When spraying, attention should be paid to the position and method of application, spraying on the back of young leaves, and adding an appropriate amount of laundry detergent to the fertilizer to ensure the fertilizer sticks to the leaves.
Cluster Pruning
Cluster pruning is also an indispensable management measure during the grape flowering and fruiting period. When the grape inflorescence is fully expanded but not fully open. The pruning targets are large clusters and secondary clusters, but not all need to be pruned, about 1/4 should be pruned. About 4/5 of the peak should be retained. The same principle applies to smaller ears, which should not be pruned too much, or even not pruned at all, just a simple pruning is sufficient.
Fruit Bagging
After grapes have been pollinated, proper bagging can effectively avoid the harm caused by diseases, pests, and birds to the fruit. It can prevent the fruit from coming into contact with chemicals, reduce contamination of the fruit, and reduce sunburn, cracking, and other adverse phenomena. Improving fruit quality and yield. When the first cluster整理 is done, bagging should be done in time, generally about three weeks after flowering. The specific bagging time is determined by the planting area. Before bagging,消毒 should be done once. The main target of sterilization is the ears, mainly methyl thiophanate and other chemicals. After the chemicals dry, bagging can begin.
The above is a brief introduction to grape flower and fruit management techniques. Management during the grape flowering and fruiting period is very important, and everyone should pay more attention to it. Today's introduction ends here. For more information, please continue to follow us!
