Sweet potato seedling raising time and method

Sweet potatoes have strong storage resistance and a relatively long sales period. Moreover, the price increases as winter approaches. Now is the time to grow sweet potato seedlings. If you want to have high sweet potato yields, seedling cultivation is the key. Let’s talk about the time and method of growing sweet potato seedlings.

1. Time Selection

For sweet potato seedling cultivation, generally large sweet potatoes are selected, which have high nutrient storage and can grow strong and healthy seedlings, which are beneficial for future transplanting and growth. Seedlings can generally be grown in February-April, around the Waking of Insects in the lunar calendar, and there are differences in the north and south. It is best to grow seedlings in early March south of the Huaihe River, and it is best to plant sweet potatoes before April north of the Huaihe River.

2. Temperature selection

The temperature for sweet potato germination is the same as that for other spring vegetables . The more suitable temperature is 12-32 degrees. Generally, it germinates faster at 25 degrees and grows faster. Special attention should be paid to the night temperature, which should not be lower than 12 degrees.

3. Placement method

When growing sweet potato seedlings, you can grow them in square or cubic spaces. There is generally no limit, and the sprouts that grow are also similar. You can arrange the sweet potato seedlings according to your actual situation and preferences. They are usually found more in cellars and hydroponic cubes, and can be placed flat in nutrient beds and special land.

4. Cultivation Methods

In terms of cultivation methods, there used to be earth pit cultivation, but now it is mostly cultivated in constant temperature boxes and greenhouses ; there is also cultivation in nutrient soil and nutrient water. Nutrient soil cultivation is suitable for large-scale cultivation, which is suitable for large-scale growers and seedling sellers. Hydroponics is better for home cultivation, and there is no need to specially make nutrient beds. No matter what method is used, sweet potato seedlings can be grown and the results are similar.

5. Preparation of nutrient soil

Sweet potatoes do not require too much nutrients for germination and growth, because sweet potatoes have modified roots. Pengda's sweet potato tubers store rich nutrients and can meet the nutritional needs of the seedling stage. You can also wait until the value is fixed after transplanting and then apply fertilizer.

6. Seedling Time

Sweet potatoes germinate relatively slowly, generally taking 25-30 days. They first root and then sprout. It takes about 30 days from sprouting to transplanting. The entire growth cycle is about 60 days. Therefore, friends who want to grow seedlings must prepare in advance and grow seedlings in time according to their planting plans.
