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
