I'll take the corn harvester as an example and briefly say:
A, useless harvester before the process is:
1, land cutting, a person will cut land on average about 3 mu per person per day, and he will be tired to death even if he leaves early and returns late. If he hires people, he will be about 100 per mu, which is counted as six days early and six nights every day 120 yuan.
2, picking corn, this is about an acre per person who goes out early and returns late every day. The number of employees is about 150 per mu.
3. It is the most tiring process to load corn into the car to pull home. The hiring cost is about 200 yuan per mu, and the car fare is about 150 per mu.
4, put the precipitation in the corn building, waiting for sale.
5. Bundling corn stalks for firewood and cooking, and asking 10 people for help in stacking Lachai River will cost about 500 yuan.
The traditional process needs five steps, and each step is expensive.
So after using the corn harvester:
General harvesters bring corn carts, and the price is also included in the price of harvesters, so we only need to hire harvesters. It's noon here, not the previous mu, and the price of every morning here in Siping Yitong this year is 1200 yuan. The car brought by the harvester directly pulls the picked corn home, and those with corn conveyors at home can go upstairs directly.
Harvesters can directly cut and return crushed corn stalks to the field, and many places have broken corn stalks balers, which can sell the crushed corn stalks to power plants. Therefore, the corn harvester only needs one process to complete the previous five processes, and it doesn't cost much. From this point of view, the emergence of corn harvester has solved the big problem of farmers' harvesting.
This is the difference, and the significance to farmers is to improve productivity and save costs without having to work so hard!
