How to reproduce sweet potatoes and how to reproduce

Sweet potato breeding method

When propagating sweet potatoes, you can use the method of cutting propagation or the method of seedling propagation. Seedling propagation is the most common propagation method, which can be planted on a large scale and has a higher survival rate, while cutting propagation is generally used when planting on a small scale.

Common methods of propagating sweet potatoes

1. Sweet potato cutting propagation

When propagating sweet potatoes by cuttings, you can use oblique cuttings. You need to select healthy, disease-free sweet potato seedlings, about 15 cm long, and then insert the sweet potato seedlings into the soil at an angle of 45 degrees. This method is simple to operate, has a high survival rate, and does not have very high requirements for the soil. It can be used in mountains and fields.

When transplanting sweet potatoes, it is best to do it after a rain when the sky is clear, because the soil at this time is relatively moist and soft, which can increase the survival rate of the sweet potato seedlings. When transplanting sweet potatoes, it is necessary to decide the appropriate number of cuttings based on the properties of the soil and the sweet potato variety.

2. Sweet potato seedling breeding

Sweet potatoes can also be propagated by seedling cultivation. When cultivating, you need to use strong and healthy sweet potato seedlings, and then cut each section into 2-3 sections for seedling cultivation. Before sowing, you need to use a carbendazim solution to soak and disinfect, and then transplant.

When planting sweet potato seedlings, you must pay attention to the spacing between rows and plants. It should not be too dense. Generally, the spacing between rows and plants can be kept at 33-43 cm. After planting, you need to water it thoroughly so that it can resume growth quickly.
