Cutting off excess vines is actually the most thorough solution, but it is also the most troublesome. When the sweet potato vine grows too vigorously, you can cut off most branches, leaving only the main vine and a few branch vines, which will not only affect the growth of sweet potato, but also control the vine from growing wildly again. The cut sweet potato vines can be taken home to feed pigs or used to fill biogas, so this method is actually good except for a little trouble.
Pick up the vines Choose a sunny day, pick up the sweet potato vines so that their roots are completely separated from the mound, and then arrange the vines in one direction, so that the vines will not block the sunlight and affect the sweet potato's absorption of sunlight. We choose sunny days because rainy days are the best weather for vines. In case the rattan breaks, the roots of the rattan may be invaded by pathogenic bacteria, so sunny days are the best weather for lifting the rattan.
Turn the branches and vines over. When sweet potato grows vigorously, it also branches fastest. Therefore, when the vine grows vigorously, it is necessary to turn over the branches of the sweet potato vine in time, so as to avoid it competing with the vine for nutrients. After the method is turned over, it should be smoothed, and the sweet potato pile should be exposed, so that the vines will not grow any longer without touching the soil, and the sweet potatoes can absorb sunlight better, so this method is also desirable.
In our countryside, spraying is controlled. Some elderly people are physically exhausted and can't turn over the sweet potato vine at all, so they choose to spray medicine to prevent it. Is this medicine? Humpty jiaozi? And then what? Dilution, these two drugs can really control the growth of vines after spraying, but will excessive amount make vines appear? Drug damage? Situation, and sweet potato is not delicious, this method is generally not recommended.
