How to Grow High-Yielding Sweet Potatoes After Wheat? A Detailed Explanation of the Cultivation Techniques

Depending on the planting method, sweet potatoes grown after wheat will differ in later growth and yield, so what exactly are the high-yield cultivation techniques for sweet potatoes after wheat?

1. Variety Selection

Choose the corresponding high-yield variety according to its use and in combination with local market demand. For the starch type, you can choose Shangshu 19, Xushu 18, etc. For the roasting type, you can choose Zheng 20, Jishu 34, etc.

2. Land Preparation

15-20 days after planting, apply 5-10 kg of urea to promote vine growth. After entering the tuber enlargement stage, apply 10-15 kg of potassium sulfate as a top dressing. Two weeks later, apply 0.5% potassium dihydrogen sulfate as a top dressing; in the later stage, apply it about once every week, spraying the leaves 2-3 times in succession. The number of waterings is determined according to weather conditions and growth rate.

5. Timely Harvest

The normal harvest of sweet potatoes after wheat is generally completed in mid-to-late October, with the specific timing determined by the local climate and the variety of sweet potatoes after wheat.

The above is the relevant introduction to the high-yield cultivation techniques for sweet potatoes after wheat, and we hope it is helpful to everyone.
