A Detailed Guide to the Cutting Propagation Technique for Potatoes

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 the editor and take a look.

1. Disinfecting the cutting knife

This point is very important. If you do not disinfect the cutting knife, you will most likely carry diseased seed pieces into the field, which will not only cause disease but very likely spread the pathogen to other seed pieces. So before cutting, besides preparing two fairly 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 potato's apical bud advantage; if the potatoes are larger, the eye-cutting method is suitable, as this method helps the potato develop roots and sprout. After cutting each potato, change the knife once. If you cut into a diseased or rotten potato, soak the knife in the disinfectant again, 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 neglected, then when the wounds are damp they are very prone to infection by other miscellaneous bacteria. So after cutting, promptly dress the seed pieces with a uniform mixture of thiophanate-methyl, agricultural streptomycin and talcum powder. Seed dressing dries the cut surface, makes the wounds easy to heal, and also kills bacteria and parasites, so seed dressing is an indispensable part of growing potatoes from cut pieces.

4. Sprouting

After seed dressing is finished, choose a fairly damp 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 sprouting, pay attention to the sprouting situation, and promptly pick out and throw away any rotten cut pieces. When the sprouts grow to about 1 cm, they can be sown.
