How to下拉 grape clusters
Are you familiar with this? The knowledge about how to下拉 grape clusters and the introduction of the timing and methods related to grape cluster pulling, including the details are as follows:
In the process of grape cultivation, pulling clusters can help improve the crowded arrangement of grape fruits and also promote even coloring, thereby enhancing the overall quality of the grapes. Good cluster pulling can even reduce the amount of maintenance work required later. Among all the methods of pulling grape clusters, using chemicals is the best. The following details the timing and methods, along with some small details to note.
1. Timing
If you pull clusters at the wrong time, it can backfire, so choosing the right time is the primary condition for pulling clusters. Generally, you can start once the fruit clusters are no longer covered by leaves, but it must stop 10 days before flowering. Therefore, it's best to start early, as the earlier the grapes are, the more sensitive they are to the chemicals.
2. Methods
The method of pulling clusters through water and fertilizer management mainly involves applying nitrogen fertilizer, but it is slow and the effect is not obvious. Small changes in the external environment can affect the results of cluster pulling. Moreover, the application of nitrogen fertilizer before flowering itself carries certain risks.
Therefore, it is recommended to use chemical methods for pulling clusters. Spraying with 4-5mg/L of gibberellic acid can effectively lengthen the inflorescence and the effect will not be influenced by changes in the surrounding environmental conditions. The safety factor of chemical cluster pulling is also higher. Using chemicals to pull grape clusters is the best choice.
3. Precautions
If the plant has diseases, cluster pulling cannot be performed, so it is necessary to prevent diseases before flowering using conventional disinfectants.
Although grape cluster pulling has many benefits for fruit quality, it is not suitable for all grape varieties. For example, after pulling clusters on Ruby Seedless grapes, there can be a significant size difference among fruits, leading to more complicated maintenance work for farmers. Therefore, the variety should be carefully considered when pulling clusters.
The above is an introduction to how to pull grape clusters and the methods related to the timing and methods of grape cluster pulling, which can serve as a reference suggestion for everyone.
