The latest course on techniques and methods of potato slicing and planting

Potatoes have been eaten, taste good, price is also cheap, so the market is huge, planting more people, and some experienced growers know, potato in addition to seed reproduction, but also can be planted with germinated potatoes, and this method is more efficient. So how exactly should it be operated? Let's take a look at it together with Xiaobian.

1, knife disinfection

This is very important. If the knife is not disinfected, it is very likely that the infected seed block will be brought to the field, which will not only cause disease, but also spread the disease to other seed blocks. Therefore, in addition to preparing two sharp knives before cutting, they also need to be disinfected with refined or 0.3% potassium permanganate solution.

2. Cut into pieces

When cutting, if it is a small and medium-sized potato to adopt the method of longitudinal cutting, so as to make full use of the advantage of potato terminal bud; if it is a larger potato is suitable for bud eye cutting method, this cutting method is conducive to potato root germination. After cutting a potato, change the cutter once. If you cut a diseased or rotten potato, soak the cutter in disinfectant again, change another cutter and continue to operate. At the same time, pay attention to that each seed block is preferably not less than 25 grams.

3. Seed dressing

Potato seed dressing is also very important, we will bring wounds to the potato when cutting, if not pay attention to management, then when it wounds, according to wet, easy to infect other miscellaneous bacteria. Therefore, after cutting into pieces, it is necessary to mix the seeds evenly with methyl thiophane, agricultural streptomycin and talcum powder in time. Seed dressing dries the cut surface, makes it easier to heal wounds, and kills bacteria and parasites, so seed dressing is an important part of potato cutting.

4. Germination

At the end of seed dressing, choose to cover it with a relatively moist cloth, and then place it in an environment with a temperature of about 15-18 degrees and a humidity of 85%. In the process of germination should pay attention to the germination situation, at the same time to pick out the rotten pieces in time to throw away, when the bud grows to about 1 cm when you can sow.

The above is an introduction to potato cutting planting technology. I hope it can help you. If you want to know more about it, please pay attention to us.
