How much does a potato planter cost? A detailed explanation of its working principle

Since the reform and opening up, China's agricultural infrastructure has improved markedly, agricultural production technology and the level of science and technology have risen significantly, and people have become increasingly dependent on agricultural machinery and equipment. Potato is a crop widely grown in China, so how much does one potato planter cost? What is its working principle?

1. How much does one potato planter cost?

Potato planter prices range from 2500-1000 yuan per unit. Small models with simple functions generally cost 2500-4000 yuan per unit, while large models with more functions generally cost 5000-10000 yuan per unit. You can choose a machine of suitable specifications according to the sowing area and planting needs.

2. What is the working principle of a potato planter?

A potato planter is a planting machine that uses a sowing system to plant block-shaped seed potatoes in an orderly manner underground. It can plant potatoes and other root and tuber crops, and can be used in conjunction with a small tractor. It integrates furrow opening, fertilizing, sowing and soil covering, and can complete fertilizing and sowing operations in one pass.

3. What are the methods for treating potato seed potatoes?

1. Seed selection

Generally, about 15 days before sowing, select tubers with fresh-looking skin, no cracking and no disease spots as seed potatoes.

2. Cutting

In order to ensure uniform emergence of potatoes, apical dominance must be broken. The method is to cut vertically down through the center of the tuber's apical bud, cutting it into two pieces, and then cut further.

3. Site disinfection

The site where seed pieces are cut and the tools used to hold the seed pieces should be sprayed with a 2% copper sulfate solution, or disinfected with plant ash. This reduces the chance of seed pieces being infected by pathogenic bacteria and viruses.

4. Cutting knife disinfection

Pathogens such as potato late blight and ring rot overwinter on seed potatoes, and the cutting knife is the main tool for spreading pathogens, especially ring rot. At present there is no specific effective pesticide for it, so efforts must be made in cutting seed pieces to prevent pathogens from spreading through the cutting knife.

The specific method is: prepare a porcelain basin containing a certain amount of 75% alcohol or 0.3% potassium permanganate solution, and place three cutting knives into the solution to soak and disinfect. These knives are used in turn, and after use each is immediately placed back into the basin for disinfection. The knife can also be burned over a flame for 20-30 seconds and then used again. This can effectively prevent ring rot, blackleg and other diseases from being transmitted through the cutting knife.

5. Requirements for cutting seed pieces

Seed pieces should not be too small; each seed piece must weigh no less than 30 grams. Larger seed pieces can enhance drought resistance and prolong the weaning period, and each seed piece must have at least one eye. Mix the cut potato pieces with plant ash as a seed treatment, which both acts as a seed fertilizer and helps prevent disease.

Potato is an important economic crop in China and even around the world. Potato planters can bring convenience to large-scale planting and improve production efficiency. You can choose and buy a potato planter according to your actual situation.
