整齐度是玉米区域试验的一个重要调查指标,也是玉米获得高产的关键。然而试验田整齐度差的现象在许多试点都不同程度地存在,直接影响到田间试验的准确度和精确度,针对玉米试验田整齐度差的状况,笔者总结出以下几点原因及改善措施。 Uniformity is an important indicator of regional testing of maize and is also the key to achieving high yield in maize. However, the phenomenon of poor uniformity of experimental field exists in many experiments to varying degrees, which has a direct impact on the accuracy and accuracy of field experiments. The author summarizes the following reasons and measures to improve the uniformity of experimental fields in maize.
