有一项新近开发的激光平地技术在革新中国的水稻和棉花种植方面存在巨大的潜力,它能够提高作物的产量,并使水管理更加有效。在中国西部和北部广大的干旱地区,它的使用将会节约大量水资源。这项先进的技术源于美国,已在北美、南美和澳大利亚的大田种植中应用多年。它使用激光发射器在田地上方形成一个直径约600米的不可见水平面,当拖拉机牵引平地机通过田地时,平地机以激光水平面
There is a huge potential for laser leveling that has recently been developed to revolutionize China’s rice and cotton cultivation by improving crop yields and making water management more efficient. Its use in the vast arid regions of western and northern China will save a lot of water. This advanced technology, derived from the United States, has been used in many fields in North America, South America and Australia for many years. It uses a laser emitter to form an invisible water level of about 600 meters in diameter above the field. When the tractor drives the grader through the field, the grader moves the laser at a laser level
