Many forest farmers know how to balance the relationship between them, but they may not know how to say it.

Let me briefly summarize:

For example, if there are too many flowers or fruits in fruit trees, that is to say, reproductive growth is vigorous, then nutritional growth is inhibited and nutrition cannot keep up. Therefore, at this time, measures should be taken to sparse flowers and fruits to prevent the later flowers and fruits from falling, or the fruit is thin.

Also, some plants will not bear fruit if they grow too much nutrition.

Then you must prune at this time, pruning the long branches first.

There are also methods of using ring glass.

You can check the details, there are many online, so I won't go into details here.

The simplest example is that some trees in rural areas are particularly tall and have lush crowns. Forest farmers will cut many knives on them with machetes and will bear fruit next year.
