Detailed Explanation of Sweet Potato Seedling Cultivation Methods and Techniques, with Cultivation Time and Precautions

Abstract Cultivation time for sweet potato seedlings: in the south, cultivation begins in February, while in the north it begins before Qingming Festival. Dormant cultivation method for sweet potato vines: when the climate warms in the second year, dig the sweet potato vines out of the cellar for cutting cultivation. Cultivation method for sweet potato roots: select thick, unmarked, robust sweet potato roots for cultivation. Precautions for sweet potato seedling cultivation: choose a suitable cultivation method according to the region, and do a good job of insulation during cultivation.

I. Cultivation time for sweet potato seedlings

1. The cultivation time for sweet potato seedlings should be determined according to the planting region and climate. Usually, cultivation time is concentrated around March. When cultivating in spring, it is generally around Awakening of Insects. The southern region can begin cultivation in February, while the northern region must complete cultivation before Qingming Festival.

2. During cultivation, because the temperature is relatively low, it should be carried out in a hotbed, and insulation measures should be taken during this period. In addition, according to the time of planting and going to market, the cultivation time can be reasonably grasped. Generally, cultivation work begins 4-5 weeks before planting sweet potato seedlings.

II. Dormant cultivation method for sweet potato vines

1. Begin dormant cultivation after harvesting sweet potatoes in autumn. Sweet potato vines can be cultivated as seedlings for the second year. After harvesting sweet potatoes, select sweet potato vines that are thick and free of pests and diseases, remove the leaves from the sweet potato vines, keep the petioles at about 1-2cm, then soak the sweet potato vines in Amphetamine ling agent for 3 minutes, take them out and dry them, and then pick out large stones and small stones from the ground.

2. Then dig a storage cellar, place the sweet potato vines neatly into the cellar, and finally cover with fine sand. This can force the sweet potato vines into dormancy. In areas with lower temperatures and prone to frost, plastic film should be appropriately covered. When the climate warms in the second year, dig the sweet potato vines out for cutting cultivation.

III. Cultivation method for sweet potato roots

1. After all sweet potatoes are harvested in autumn, select thick, unmarked, robust sweet potato roots for cultivation. Keep about 3 nodes on each root, then remove the leaves, and then control the size of the cultivation room according to the number being cultivated. For greenhouse cultivation, reasonably control the plant spacing and dig the cultivation pits well.

2. After planting the sweet potato roots, it is necessary to stretch wire according to the planting row spacing and fix it, then connect the sweet potato roots and the wire to each other. After the sweet potato roots sprout, select about 3 new shoots on each sweet potato root. The new shoots should all correspond well to the string, so that later the sweet potato vines can climb and grow along the string.

IV. Precautions for sweet potato seedling cultivation

1. Because of differences in region, temperature, climate and other environments, the cultivation time also differs, and there are many different cultivation methods. Therefore, during cultivation, a suitable cultivation method should be reasonably selected according to personal planting techniques and region.

2. The method of cultivating sweet potato roots can make full use of planting space. At the same time, when the cultivation volume is relatively large, it can effectively increase sweet potato yield. Secondly, each cultivation method has many different advantages and disadvantages. No matter which cultivation method is chosen, the temperature should be reasonably controlled during cultivation, which is beneficial to the robust growth of sweet potatoes.
