To manage spring care of late-sown wheat well, it should be carried out according to its characteristics.
Every year there are always some wheat fields sown relatively late. The characteristics of late-sown wheat: First, the tillering period is short. Because sowing is late and emergence is late, there is no tillering period before winter, and the spring tillering period is generally less than 20 days, so the number of tillers per plant is small, and the tillering roots are also few, which is the main reason for slow growth in spring.

How should weak winter wheat seedlings be managed?
After winter wheat emerges, due to the influence of natural conditions and cultivation measures, various types of weak seedlings often form.

What to do when wheat seedlings are weak and sparse? Apply fertilizer in time to promote tillering
After wheat begins tillering, the number of tillers increases continuously with the growth and development of the plant, and the total number of stems and tillers reaches its maximum around jointing. After that, the later-emerging tillers die off one after another due to insufficient nutrients and other reasons, and the number of stems and tillers becomes basically stable only after heading. Generally, after tillers emerge
