Recently, in Yangzhuang Village, Ninghe Town, Ninghe District, Tianjin, three large-horsepower tractors were hung and the flat shovel was tightened to work on the ground. We saw far away that there was a laser transmitter of more than 2 meters in the field, which was constantly spinning, and all three tractors were working under its “command”.
Taking advantage of the rest time, the operator Gu Shiman began to talk about how the laser pointer leveling machine works: “There is a laser receiver on the machine, the laser receiver will receive the message from the laser transmitter, and the tool shovel on the machine passes through the control box. Realize automatic lifting, shovel in high places, put some soil in low places, make the land more flat. But the leveling work is a technical job, you have to make a rough judgment before driving, look at the ground Where is the squat? If the plot is low in the east and west, drive from the east to the west when driving…”
Speaking of laser leveling, Dong Wensen, chairman of Tianjin Xinghe Agricultural Machinery Technical Service Cooperative, deeply felt that “last year, I circulated 1,500 mu of land for planting rice. The paddy field requires very high level of land. If transplanted The land is not flat, and there will be deep and shallow after the water is applied, which is not conducive to the growth of the seedlings.”
“And save water, save electricity, and produce high yields.” Dong Wensen added that the uneven water is easy to flow out, causing waste of water resources; in some places, the water is already high, and some places are still dry, and water cannot be used effectively. Resources. Since water is needed to supply water to the ground, saving water means saving electricity. In this case, water and electricity can save at least half. It can also increase land utilization and increase production by more than 10%.
According to Chen Zhiqing, senior engineer of the Agricultural Machinery Management Office of the Tianjin Rural Work Committee, the flatness of farmland in Tianjin is generally poor. Generally, the flatness deviation of the same plot exceeds 15-20 cm, and some can even reach several tens of centimeters, which is not only unfavorable for large-scale agricultural operation, but also not conducive to agricultural irrigation. In agricultural irrigation, there is often a situation in which “the drought is over there”. The use of laser flat ground to carry out accurate flat land operation can ensure that the flatness of the working block radius within 400 meters is less than 5 cm, and improve the flatness of cultivated land.
Last year, Dong Wensen’s paddy field was the first time for the laser pointer to work on the ground. Due to tight time and heavy tasks, the operator only worked for more than 30 days, and did not let the land leveling reach its expected result. So this year decided to continue. Work on the ground. “This technology is so useful, I think it is necessary.”
Laser leveling is a characteristic agricultural machine operation in Tianjin. The technology has been promoted since 2010. For laser leveling operations and quality, Tianjin grants 50 yuan per mu. Guo Xiangzhi, head of the Service Guidance Section of the Agricultural Machinery Development Service Center in Ninghe District of Tianjin, said that Ninghe District has implemented more than 100,000 mu of land-level operations in recent years. Through this subsidy policy, the villagers’ land management rights have been promoted and the planting benefits have been improved.
