Heilongjiang 八五六农场: "Laser flat" to create "precise agriculture"

In this autumn's land consolidation, the farm with the largest rice planting area in China, Heilongjiang Nongken 856 Farm, has continuously improved its scientific and technological content and actively created “precise agriculture” by applying the new technology of “laser flat land”.

In the past few days, at the site of 855,000 mu of paddy fields in the 856 farm of Hulin City, a large tractor equipped with a laser receiver was placed under the command of a laser transmitter with a scraper blade to scientifically and accurately comb. farmland. In a twinkling of an eye, the black land, which was originally high and low, was at the same level.

Wang Xinglin, director of the twelfth management area of ​​856 Farm in Hulin City: This is the laser transmitter. The horizontal light emitted by it feels the light-sensing receiver on the grader. After receiving it, it transmits the signal to the hydraulic system of the whole locomotive, adjusts the working state of the grader, and achieves the function of leveling the land.

It is understood that the laser emitter forms a reference plane over the site of the ground preparation by emitting a very fine laser beam capable of rotating 360°. The receiver mounted on the shovel, after receiving the laser signal, passes the controller operation processing, and then transmits the corrected signal to the hydraulic control valve, and controls the oil cylinder on the shovel through the hydraulic system to achieve the purpose of leveling the land.

Wang Xinglin, the director of the twelfth management area of ​​856 Farm in Hulin City: After using the laser leveling machine to flatten the ground, the original abandoned pool can be eliminated, which is conducive to the management of the water layer, and also conducive to mechanical operations, so that (may) be large Improve rice planting area and land utilization rate. The application of the laser grader, according to the soil's highland error, its (working) efficiency, between 50-100 acres per day.

According to reports, after years of farming, the flatness of paddy fields is poor, and the phenomenon of “big flatness and unevenness” is widespread, which not only increases farmers' planting costs, but also brings inconvenience to agricultural production such as mechanical transplanting and field management. Using the modern technology of "laser", it can flatten all cultivated land within 20 cm of high ground error, so that the ground level can reach positive and negative error of 2 cm, the depth of water layer is consistent, and water saving is more than 30%, thereby reducing fertilizer loss and improving In the next year, crop yields and economic benefits will increase by an average of 100 yuan per mu.
