Potato invented potato film planter
Da'an Town, Yutian County, Tangshan City, Hebei Province is located at the junction of Beijing, Tianjin and Tang, where large-scale planting of potatoes began more than ten years ago. As the cultivation of potatoes requires many procedures such as turning soil, fertilizing, planting, and laminating, it is often the entire family who embarks on spring plowing. People and livestock are all on the same line, and it is difficult to find a helper nearby. External recruitment of workers can greatly increase production costs. Song Ruihua is an ordinary farmer in Shihe Village, Da'an Township. As the main laborer at home, he feels even harder to plow on spring crops, so he has sprouted the idea of ​​developing potato film-covering planters. However, it is conceivable that the difficulty in turning, planting, fertilizing, covering soil, and laminating membranes at the same time in one link. Song Ruihua, who had invented three oil-saving devices with an oil saving rate of 30%, was not frustrated by the difficulties. He often consulted the data at the night, conceived designs, and drew drawings; during the day, he saw, assembled, and debugged. Seeing that the old song had been working day and night, many people in the village advised him: “What people haven’t got out of the experts, you’re doing what you’re trying to do? You can’t do anything at the end of the day, you’re still ruining the field, or you’re doing it early. Seriously.†In this regard, Lao Song just reported a faint smile. In the spring of 2001, Song Ruihua developed the first potato laminator and small multi-purpose tiller. However, Lao Song feared that the performance of the machine was unstable and caused losses to others. He decided to take his own ground test first. As a result, it was found that the average output of mechanical operations was slightly higher than that of artificial cultivation in terms of seedling growth, potato quality and yield. The news of the success of the potato laminator experiment developed by Song Ruihua spread wildly and caused a sensation in the local area. Everyone ran to Lao Song's home to watch and ask about the situation. Lao Song introduced it to everyone while demonstrating: “The six acres of land in my family, if you use the old tradition of farming, you have to hire 8 people, 2 cows, plus money and money, it costs 400 yuan. This child has this Machine, as long as 100 yuan on it, not only saving time and money." On this basis, Song Ruihua has repeatedly improved the two kinds of machinery to make its performance more stable. Today, potato laminating machines and small-scale multi-purpose tillers have all achieved a number of functions such as freely adjusting the planting depth, fertilizer usage, and soil plowing, and can be used for planting various crops such as potato and corn.
