As the densely populated hawthorn garden uses the method of thinning first and then thinning, it has been put into production early and has the advantages of high density and dense planting and thin planting, and has been gradually recognized by people in recent years.

We conducted a survey on the densely populated hawthorn garden of 45 mu (1.5 × 5 row spacing) plan and summarized the following better treatment methods.
