Problems solved by technology

[0003] 1) The existing sales of sweet potato seedlings are mainly sold locally by small enterprises and professional seedling raising households. The sales method is reservation or door-to-door purchase by customers. Therefore, it is impossible to distribute through the conventional seed sales network, which seriously restricts the scale of seedlings Production and promotion of new varieties
[0004] 2) Since the potato seedlings are cut in batches and grow continuously, usually a batch of seedlings can be cut in about a week, and the storage period of the potato seedlings is only 1 to 3 days. Under the existing production and sales mode, farmers do not need to They will come to buy seedlings on sunny days with high temperature and drought. During this period, the potato seedlings that can be cut will be lost or wasted; on rainy days, a large number of farmers

Abstract

The invention discloses a production method of a sweet potato sprout, and belongs to the technical field of culture of seedling of crops. The production method comprises the steps of: (1) seeding potato seeds and culturing seedlings; (2) preparing a paper micro nutrition bowl; (3) cutting the seedlings and performing cottage; (4) rooting; and (5) binning, transporting and selling, etc. By adopting the production method of the sweet potato sprout, the seedling output per unit area is greatly increased, the quality of cutting seedlings is ensured, the effective seedling rate is up to 97 to 98%, the working intensity in culture of the seedlings and the cost of seedling are obviously reduced, the production efficiency is improved, and therefore the industrial production is realized; in addition, the sprout in the paper bowl has the advantages of being small in size, light in weight, convenient to transport, flexible in planting season and high in survival rate, and extending the shelf life to be up to 15 to 20 days. The production method of the sweet potato sprout can be popularized and applied in sweet potato production areas and seed and seedlings companies.

Description

technical field [0001] The invention relates to the technical field of crop seedling cultivation, in particular to a production method of sweet potato seedlings. Background technique [0002] Sweet potato production has always used the traditional planting method of seed potato seedling cultivation-cutting cuttings. Generally, seedlings are raised in the middle and late March, and from late April to mid-June, the robust potato seedlings with a length of 25 to 30 cm and 5 to 7 expanded leaves are cut in batches for cutting planting in the production field. Since the cut potato seedlings do not have roots, they need to be rooted and grown under suitable temperature and soil humidity conditions. For small-scale farmers for self-propagation and self-use, this traditional planting mode of sweet potato seedlings is not inappropriate. In the seasons when the temperature is suitable in late spring and early summer, cutting seedlings while waiting for rainy days, or timely i...
