Overwintering cuttage method of purple sweet potato vines

Abstract

The invention discloses an overwintering cuttage method of purple sweet potato vines. The overwintering cuttage method comprises the following steps: (1) preparing purple sweet potato vines, (2) treating the purple sweet potato vines, (3) carrying out pit storage treatment, and (4) cutting the purple sweet potato vines. In comparison with a conventional sweet potato seed buried seedling cultivating method, the overwintering cuttage method disclosed by the invention greatly reduces the cost, and improves the use value of the purple sweet potato vines, the purple sweet potato vines after pit storage are relatively high in survival rate and seedling rate, and the method is simple and practical, and has a very good promotional value.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for overwintering purple potato vine cuttings. Background technique [0002] At present, most of the purple sweet potato planting methods are to store the purple sweet potato harvested in the previous season with wet sand, then bury it to raise seedlings, and finally plant the purple sweet potato seedlings by cuttings. On the one hand, this traditional planting method consumes a large amount of seed potatoes, and black spot, soft rot, root rot, nematode and other harmful seed potatoes will break out, resulting in a large number of rotten potatoes. On the other hand, the cost of raising seed potatoes Time-consuming, high cost, also delayed the transfer period of sweet potato seedlings. Therefore, some people try to use wet sand to store purple potato vines for overwintering, and then propagate them by cuttings. However, when only wet sand is used for storage, the wate...

Problems solved by technology

On the one hand, this traditional planting method consumes a large amount of seed potatoes, and black spot, soft rot, root rot, nematode and other harmful seed potatoes will break out, resulting in a large number of rotten potatoes. On the other hand, the cost of raising seed potatoes Time-consuming, high cost, and delayed the transfer period of sweet potato seedlings

Therefore, some people try to use wet sand to store purple sweet potato vines for overwintering, and then propagate them by cuttings. However, when only wet sand is used for storage, the water is not easy to control, and it is difficult to survive the winter. Moreover, the survival rate and emergence rate in the later period are low, which affects normal planting.
