土壤样品采集是一项十分重要的工作,其正确与否直接关系到化验结果能否正确地反映土壤实际。通常采样造成的误差,远比化验造成的误差要大。前人早已证明,即使田间取样做得比较严格,而由于取样及样品处理所产生的标准误差,比分样及化验所引起的也要大3—6倍。因而,不按规定采样将给科研和生产造成莫大损失。近年来,有些同志对土样的采集不大重视,有的也不够熟悉。采集的土样往往 Soil sample collection is a very important work, its correctness is directly related to whether the test results correctly reflect the actual soil. The error caused by sampling is far greater than the error caused by the test. It has been proven long ago by our predecessors that even sampling in the fields and the standard errors caused by sample processing are even 3 to 6 times greater than those caused by sampling and testing. Therefore, not according to the provisions of the sample will cause great losses of scientific research and production. In recent years, some comrades have paid little attention to the collection of soil samples and some are not familiar with it. Collection of soil samples often
