Sweet potato tips
In the period of vegetative growth and reproductive growth of sweet potato, the expansion of tubers requires large amounts of nutrients. At this time, the potato vines grow many adventitious roots and strive to compete for nutrients with the potatoes. In order to prevent the potato and the potato block from competing for nutrients, the former had to pay attention to the overturning of the vine. The potato vine was lifted by hand and turned from one side to the other. Although this eradicates the adventitious roots, it has caused great damage to the tree plant, in vain. For this reason, scientific and technical personnel made a concluding remark to “turn sweet vines over half of their output,†and advocated the use of vines. Lifting vines is both labor-saving and effective. It is not convenient to use a two-handed hand when lifting the vine. It is recommended to make a small three-toothed or four-toothed hook and put it on a wooden handle. When you use it, hook the yam along the furrow and you can pick it up slightly. And fast.
