Detailed Explanation of Key Points of Potato Cut-Seed Planting Techniques

Everyone has eaten potatoes; they taste good and are cheap, so the market is huge and many people grow them. Experienced growers know that besides propagating potatoes from seed, you can also plant sprouted potatoes, and this method is more efficient. So how exactly do you do it? Follow along with the editor and take a look.

1. Cutting knife disinfection

This point is very important. If the cutting knife is not disinfected, diseased seed pieces are very likely to be brought into the field, which will not only cause disease but also very likely spread the pathogen to other seed pieces. Therefore, before cutting, besides preparing two relatively sharp cutting knives, you also need to disinfect and sterilize them with alcohol or a 0.3% potassium permanganate solution.

2. Cutting

When cutting, if the potatoes are small or medium-sized, use the lengthwise cutting method, so as to make full use of the apical bud advantage of the potato; if the potatoes are larger, the eye-cutting method is suitable, as this cutting method helps the potato develop roots and sprout. After cutting each potato, replace the knife once. If you cut into a diseased or rotten potato, soak the knife again in the disinfectant solution, switch to the other knife and continue, and also note that each seed piece should preferably not be less than 25 grams.

3. Seed dressing

Seed dressing for potatoes is equally important. Cutting creates wounds on the potatoes, and if management is not careful, then when the wounds are damp, they are very prone to infection by other miscellaneous bacteria. Therefore, after cutting, promptly dress the seed pieces with a well-mixed blend of thiophanate-methyl, agricultural streptomycin and talcum powder. Seed dressing dries the cut surface, making the wounds easy to heal, and at the same time it can kill bacteria and parasites, so potato seed dressing is an indispensable step in cut-seed planting.

4. Sprouting

After seed dressing is finished, choose a relatively moist cloth to cover them, then place them in an environment with a temperature of about 15-18 degrees and a humidity of 85% to sprout. During the sprouting process, pay attention to the sprouting situation, and promptly pick out and throw away the rotten cut pieces. When the sprouts grow to about 1 cm, they can be sown.
