From winter to spring, the national locust tree planting has a better time to fertilize. Now, let the editor bring you what are the precautions when fertilizing the national locust tree?
In fact, April is a very suitable season for the fertilization of the Chinese locust tree, because the temperature gradually rises, and the frozen locust tree in winter has gradually recovered.
At this time, irrigating and applying spring fertilizer to the Chinese locust tree can effectively promote the absorption of phosphorus and potassium fertilizer by the roots, and further promote the rapid development of the locust tree seedlings. It is very important for the entire growth cycle of the tree species. So what are the precautions?
Fertilization in spring should be based on organic fertilizer. Do not apply too much per mu of land at one time, preferably at 2000kg.
In addition, fertilization should be carried out after spring irrigation. When the weather turns hot, nitrogen fertilizer and urea can be added. This can provide sufficient nutrients for the roots and promote their spring growth. In addition, we also remind consumers that fertilization should follow a certain proportion and do not think that more fertilization is good, so as to avoid the death of seedling roots from burns.
