The author found that when many farmers plant sweet potatoes in the spring, they transplant the medlar rooted on the nursery bed with roots. This is unscientific.
When planting yam, the roots should be cut off. The main reasons are as follows: First, it is conducive to disease prevention. Sweet potato black spot disease only harms the white stems and root parts of the seedlings in the underground, and does not harm the aerial parts. Cutting off the roots is equivalent to removing the germs, which has a preventive effect on dark spots. The second is to help ease seedlings. After the long pods are planted in the ground, they often do not rise straight and the leaves are difficult to stretch, which is not conducive to photosynthesis and slow seedling growth. In spring, the wind is often windy, the seedlings are blown by the wind, and the leaves are repeatedly rubbed on the ground, which is not conducive to growth and easing seedlings. It is better to cut off the roots. Cutting off the root can also make the root primordium to be concentrated and tidy, and the sweet potato can be easily harvested.
