Pruning of yam vine is an indispensable part of yam planting, which not only helps to improve the yield and quality of yam, but also enhances the stress resistance of yam. This article will detail the pruning techniques of yam vines to help growers better manage yams.
1. Pruning time.
The pruning of yam vines is mainly carried out in summer and autumn. Summer pruning is mainly carried out from June to August, when the yam vine grows vigorously, and it is necessary to carry out topping, topping, control plant height, and promote the growth of side branches. Autumn pruning is mainly carried out from October to November, when the yam vine begins to enter the dormant period, which can promote the return of nutrients and improve the quality and yield of yams.
Second, the pruning method.
1.Topping: During the vigorous growth period of the yam vine, the young shoots at the top of the main vine are removed to control the plant height and promote the growth of side branches. Topping can be done multiple times to maintain the plant shape of the yam vine.
2.Topping: Cut off part of the top of the main vine of the yam vine to control the plant shape and promote the growth of side branches. A certain number of leaves should be left during topping to ensure the normal progress of photosynthesis.
3.Pruning side branches: During the growth of yam vines, side branches will grow continuously and need to be pruned. When pruning, keep an appropriate amount of side branches to increase the area of photosynthesis. When pruning, cut off from the base of the side branches to avoid damaging other parts.
4.Pruning diseased branches: During the growth of yam vines, diseased branches may appear and need to be pruned in time. When pruning diseased branches, they should be cut off from the base and treated intensively to prevent the spread of the disease.
3. Precautions.
1.When pruning, it is necessary to choose sunny weather to avoid pruning in rainy days and causing diseases.
2.Use sharp scissors or blades when trimming to ensure that the cut is smooth and neat.
3.After pruning, fertilizer and watering should be applied in time to promote the growth of yam vines.
4.In the process of growing yam vines, it is necessary to pay attention to observation, timely detection and treatment of pests and diseases.
