1、 According to plant judgment

1. One or two year old seedlings: maintain appropriate planting spacing, which can be conducive to the later growth. If the planting is too dense, it is difficult to ensure the growth. If the planting is too sparse, the land resources are not well used. If one or two-year-old seedlings are planted, their growth time is short and their plant shape is relatively small. In order to make better use of the land, the plant spacing and row spacing can be set as 20cm × 50cm or 40cm × 25cm, these two ranges are more appropriate

2. Three year old seedlings: if three-year-old seedlings are planted, the plant shape has become larger at this time, and the plant spacing and row spacing can be set as 40cm × 50cm。

3. More than three years old: if the plant is more than three years old, the plant spacing and row spacing can be set as 50cm × 60cm, the specific spacing can be adjusted in time according to the situation, and the problems of water and fertilizer, sunshine and later management need to be considered

2、 Judging by purpose

1. Production area: if peony is planted in the production area, it is necessary to ensure the yield. Within the appropriate range, plant it as densely as possible, according to 50cm × 60cm plant spacing and row spacing

2. Viewing area: for the viewing area, the planting does not need to be too dense, and the plant spacing and row spacing can be set to 100cm × 100cm。
