美国阿拉斯加奥本的南方经济协会国家耕作机械实验室的农业工程师罗伯特·L·斯凯费说:由于车辆往来造成的土壤紧压度会降低作物产量,而且田间机器驾驶不得当往往导致作物根区土壤压实。使土壤紧压度限制在一个小范围的一种方法是自动引导同区域内的田间车辆。 Robert L. Skife, an agricultural engineer at the National Farming Machinery Laboratory at the Southern Economic Association’s Auburn, Auburn, Alaska, said: Soil stress due to vehicle traffic can reduce crop yields, and improper driving of field machines often leads to crop root zone Soil compaction. One way to limit soil stress to a small area is to automatically guide field vehicles in the same area.
