The latest pruning methods of cold potato vines

Friends who have planted sweet potato all know that sweet potato is a kind of plant with strong sprouting power on the ground. in production and planting, it is generally necessary to fight and plant in order not to cause ground congestion, to keep branches, stems and leaves fully engaged in photosynthesis, to produce nutrition, and to ensure good growth. But even if the scaffolding is built, it still needs to be pruned at all stages, so as to maintain the best plant structure.

First, thinning branches

It is necessary to select side branches when they grow to more than 1 meter after planting. Generally, a main vine should leave 6 to 7 side branches, and then the others should be sparse, leaving staggered knots on both sides, and strong and strong side branches. Weak branches and bad nodes should be removed. In the future, sturdy branches should be kept step by step. The more they go up, they can stay a little more, but there are also a lot of them removed.

Second, pick the heart

When the main vine grows to 2 meters, it should be plucked to prevent it from growing again. All selected lateral branches must stop growing forcefully when they grow to more than 1 meter. Then the remaining branches grow to the proper length to pick the heart, constantly pick the heart, develop lateral branches, and inhibit the top growth.

Third, removal of buds

For the bud at the base of the main vine to remove, can not sprout, avoid the lower foot closed, not ventilated, increase the risk of disease. For clustered ducks, leave one or two strong buds and then remove the other buds. This ensures that the strongest branches are pulled out. For top buds, which consume nutrients and bloom in summer, should be thinned.

Fourth, picking leaves

Remove old, diseased or yellowed leaves at any time in summer to reduce consumption, ventilation and light, and maintain photosynthetic utilization. But do not remove the leaves near the underground rhizome, these leaves have a shading effect. Can prevent the soil from being too dry or dehydrated.

Fifth, cutting vines

For the crazy growth of new shoots in midsummer or some susceptible vines must be cut off in time, so as to prevent the spread of diseases, but also to ensure that nutrition is mainly supplied to underground rhizomes. To ensure growth, the aboveground part of the summer shoots are not retained, or the removal of part of the spring shoots, in exchange for summer shoots, maintain vitality, can also ensure that the seeds mature.

Planting sweet potatoes, generally do not set up the frame should be planted at a distance, pruning can not be less. Photosynthesis would be much better if it were built, but the pruning would also be put into practice. The main pruning is in summer, which is mainly to adjust the plant structure to ensure the centralized supply of nutrients. To ensure the quality of inflated roots.
