Why does sweet potato planting lead to slow returning to early planting?
In some areas, early sweet potatoes are planted in order to save man-hours, and they are planted in the ditch or planted after heavy rain. Although this method can ensure a high survival rate, the long-term growth of potato seedlings often occurs. The reason is that after the flood irrigation, the soil temperature is cool, the root growth is slow, and the soil becomes hardened to hinder the growth of the root system. Using the method of pouring water into the leaf litter, the soil is rich in oxygen, the soil temperature is higher, the potato seedlings return quickly, and the growth potential is strong. 1.
