Paulownia afforestation is a highly seasonal work. In order to ensure the quality of afforestation, the most suitable afforestation season must be selected. Different regions in the world have different topography and different microclimates. In order to achieve satisfactory afforestation results, the most suitable afforestation season and time must be selected according to local conditions.
Afforestation in spring
Spring is the best paulownia afforestation season in most areas. At this time, the temperature rises, the soil temperature rises, and the soil is moist. Early spring planting coincides with the early stage of the most vigorous rooting stage of Paulownia before germination.
Afforestation in autumn
In autumn, the temperature gradually drops, the soil moisture is relatively stable, the seedlings are deciduous, and the transpiration of the above-ground parts is greatly reduced, while the roots of the seedlings still have a certain activity, and it is easy to restore vitality after planting. Survival rate, and the growth of young trees is also relatively large. Therefore, it can be planted in autumn in areas where the soil is moist and the climate is warm.
Afforestation in winter
In winter, the soil does not freeze or the freezing period is very short, and the weather is not very cold and dry in the south, and it can also be afforested in winter. Generally, it can be planted from late autumn to early spring.
