Abstract

The invention discloses an efficient seedling raising method for sweet potatoes. The method comprises the following steps that 1, after sweet potatoes are harvested in autumn every year, potato vineswithout pests and diseases are selected, the top ends of petioles are cut, leaves are removed, the middles of the petioles are knotted, and 8-10th sections counted downwards from the morphological upper ends of the potato vines are cut; 2, the potato vines are put into dormancy liquid for soaking treatment and then taken out; 3, after the two ends of each potato vine are coated with ointments, thepotato vines are covered with transparent plastic film; 4, every 25-30 days, illumination treatment is conducted on the covered potato vines, and after illumination is completed, the plastic film isremoved for ventilation treatment; 5, in spring of next year, the potato vines are taken out, every two sections are cut to serve as seedlings, and cuttage seedling raising is conducted. By means of the efficient seedling raising method for the sweet potatoes, the operation is simple, the potato vines harvested in autumn are adopted as the seedlings, the cost is low, the needs for large-scale industrialized seedling raising are met, the seedlings after cuttage are rapid in survival and good in growth momentum, and the yield of the sweet potatoes is high.

Description

technical field [0001] The invention belongs to the technical field of sweet potato seedling cultivation, and in particular relates to a method for efficiently raising sweet potato seedlings. Background technique [0002] Sweet potato is one of the main autumn grains. It is not only high in yield and strong in disaster resistance, but also rich in nutrition and suitable for processing. It can be used to make noodles, vermicelli, vermicelli and sugar, extract citric acid, convert ethanol, etc., to improve people's lives and development. The commodity economy plays a major role. The key to high yield of sweet potato is to cultivate good seedlings. Only when strong seedlings are planted early can a good foundation for high yield and harvest be laid. The traditional technology of raising sweet potato seedlings is to store the sweet potatoes harvested in autumn, plant and cultivate potato vines in spring, and then cut the potato vines into vine segments and propagate them into s...
