"The plantations under Princess Shaoyi's name verified that through the method of seedling reproduction, the vines of the sweet potatoes that reproduced through seedlings grew faster and were more luxuriant. Every acre of vines was equivalent to planting ten acres of sweet potatoes using the original method. More than 70 acres of vines were planted, resolving the problem of not having enough vines for the large-scale promotion of sweet potato planting. The goal of mass and widespread planting was achieved. Currently, the sweet potatoes have reproduced through two rounds of seedling reproduction. It was discovered that seedling reproduction also greatly increased the survival rate and yield of the sweet potatoes."
