Last Updated: 2024/11/05, In recent ten years, the spring drought in Lincheng County is serious, the air temperature rises quickly, and the ground temperature rises slowly, especially after the newly planted Robinia pseudoacacia seedlings are watered, the ground temperature is low for a long time, so that the aboveground part has sprouted and grown, but the root system recovers slowly and the survival rate of Robinia pseudoacacia decreases. In autumn, the temperature decreased gradually, the transpiration was low, the water content in the soil was stable, and the Robinia pseudoacacia seedlings accumulated rich nutrients. There is no natural dormancy period for tree roots, and the roots of Robinia pseudoacacia planted in autumn can resume growth when the soil temperature is still high, as long as the permafrost is not thick in winter.

In autumn, the temperature decreased gradually, the transpiration was low, the water content in the soil was stable, and the Robinia pseudoacacia seedlings accumulated rich nutrients. The root system of the tree has no natural dormancy period, and the root system of Robinia pseudoacacia planted in autumn can resume growth when the soil temperature is still high. As long as the permafrost layer is not thick in winter, the root system of the lower layer still has a certain growth, and it sprouts early and grows healthily in the next spring. The survival rate can reach more than 95%.

The planting time can be planted from defoliation to soil freezing, but it is better to plant as soon as the leaves fall.

Tree specifications are generally cut off for afforestation, and 30 cm of seedling stem can be retained.

The planting technology is 3-5 cm deeper than that in spring, and the soil should be stepped on. Immediately after planting, the trees are fully watered. After watering, the soil can be piled up for the winter, and it is best to bury them all. In the spring of the following year, water was watered again conditionally. After underwater infiltration, cover 5cm of soil, unconditionally, the mound will be slightly removed, exposing 10 cm of seedling stem.
