Method for cultivating Sophora japonica
1, sowing
Sophora japonica looks tall and big, but it can actually be propagated with seeds. Choose mature and full seeds, soak them in warm water for 24 hours, take them out, put them in 2~3 times of fine sand, and then put them in an environment of about 20℃ to accelerate germination. In the process of accelerating germination, Dong Fan should be used frequently to ensure the consistent temperature of seeds.
After the seeds germinate, they can be planted. It should be noted that the root system of Sophora japonica is relatively long, so it is necessary to choose a larger and deeper flowerpot. It is best to plant it in an open field, grow faster, and then transplant it into a pot after it grows into a small plant.
2, thinning seedlings
When the plant grows to 10~ 15 cm in the year of sowing, it can be potted, and a deeper flowerpot can be selected to ensure sufficient sunshine. For some fine seedlings, they can be removed directly.
Step 3 apply fertilizer
Adequate nutrients contribute to the growth of Sophora japonica. During the growth period of Sophora japonica, sprinkle a little granular fertilizer around the pot soil, then water it, or directly fill it with fertilizer water. Water and loosen the soil in time after fertilization in small flowerpots. Bean cakes, horseshoe slices and horns are generally used as fertilizers at home, and then used after fermentation.
prune
The growth rate of Sophora japonica is moderate, and the top should be topped in time during the seedling growth period to promote branching. Cut off some aging and yellow branches and leaves in time.
