High-Yield Sweet Potato Cultivation Techniques: How to Achieve a Yield of Ten Thousand Jin

Prepare a plot of sandy loam land, deep plow it and apply sufficient base fertilizer, then form ridges 70cm wide and 20cm high. Then select some healthy, high-yielding, high-quality sweet potato varieties, cut them into small pieces, and plant them on the ridges at a spacing of 30-60cm. Finally, cover with soil, add a layer of decomposed manure fertilizer, and cover with plastic film. After sprouts emerge, carry out basic management tasks such as watering and fertilizing, intertillage and earthing up, and pest and disease control, and a high yield of ten thousand jin can be achieved.

Detailed Explanation of Ten Thousand Jin Sweet Potato Cultivation Techniques:

1. Select High-Quality Seedlings of Superior Varieties

High-yielding sweet potatoes are inseparable from high-quality seedlings. High-quality sweet potato seedlings can increase yield, set tubers early, and have strong disease resistance. High-quality sweet potato seedlings generally have short internodes, three to five nodes, and a seedling height of 20 to 30cm.

2. Advocate Ridge Cultivation

Small ridges are generally single-row cultivation, with a ridge spacing of 70cm and a ridge height of 15 to 20cm; large ridges are double-row cultivation, with a ridge spacing of 85 to 95cm and a ridge height of 25cm.

3. Focus on the Application of Potassium Fertilizer

As a high-yielding crop variety, sweet potato has considerable fertilizer demands, with the greatest demand being for potassium fertilizer. The fertilization principle for sweet potato is mainly potassium fertilizer, with an appropriate amount of nitrogen fertilizer, and potassium combined with phosphorus.

4. Use Plastic Film Mulch for Timely Early Planting

Plastic film mulch can be used for timely early planting, which can extend the growth period of sweet potato and increase the accumulation of nutrients.

5. Improved Horizontal Planting

Improved horizontal planting means increasing the number of nodes of the sweet potato seedling that enter the soil, and also increasing the number of tuber-setting nodes. This reduces the consumption of nutrients and water, shortens the seedling recovery time, and increases the survival rate of planting.

The above is the relevant introduction to ten thousand jin sweet potato cultivation techniques, and we hope it is helpful to everyone.
