Potato Spring Management of Promoting Roots and Strengthening Seedlings

Potato plants require a large amount of nutrients and water from the soil for growth and tuber enlargement. The development and absorption capacity of the root system determine the robustness of the potato plant, tuber yield, and quality. Potatoes generally sprout first, then develop roots. Slow root growth leads to poor sprouting and growth, thin stems, and weak disease resistance, making them susceptible to soil-borne diseases such as black scurf and black shank. Therefore, promoting potato root development and improving root absorption capacity is key to high-quality and high-yield potatoes.

I. Methods to Promote Potato Root Development

Applying water-soluble fertilizer containing amino acids before sprouting and during the post-emergence growth period can provide the impetus for root growth and development, enhance root vitality, promote root development, and encourage the growth of more and stronger roots.

1. Applying fertilizer in furrows before sprouting allows for direct absorption by the tubers, resulting in high efficiency, inducing new root growth, and promoting earlier sprouting.

2. Apply when seedlings are about 10 cm tall to induce the growth of fine roots, support and elevate seedlings, and enhance resistance to low temperatures and drought.

3. Apply before canopy closure to promote root regrowth and provide a good root system for tuber enlargement.
