Methods for Controlling Anthracnose in Pomegranate Cutting Seedlings During the Seedling Stage
Pomegranate cutting propagation is the main method for propagating pomegranate seedlings. It has the characteristics of rapid seedling formation, fast emergence, and a high survival rate after planting. During the growth period of pomegranate seedlings, the high-temperature and rainy climate conditions make anthracnose prone to occur. If not controlled in time, it can cause leaf drop, dead shoot tips, or dead

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
